SKIN CAP

Skin-Cap spray is being heavily advertised in the lay press and I am
encountering patients on a daily to weekly basis asking about it.
Skin-Cap spray is produced in Madrid, Spain by the Cheminova Corporation.
It has been used in Europe for about 10 years without any significant
reported side effects. It is FDA registered in the U.S. to treat seborrheic
dermatitis and has been available in the U.S., via mail order, for about 1
year. I have tried it on about 30 patients and have achieved an
effectiveness rate of 100%, the majority with total clearing of their
plaques in 3-6 weeks.I have used it side by side in about 4 patients with
Dovonex and Temovate and it has been more effective than either one alone
or the two in combination! I have also used it in combination with PUVA,
etretinate, and methotrexate with excellent results. (It cleared the
remaining resistant plaques in several patients using methotrexate
without the need to increase the dose of MTX, in fact we are considering
reducing the dose of MTX!!!!!!). There have been rumors that the product
contains some form of steroid, but our chromotographic investigations
reveal no steroid peaks, and, as mentioned, it performs better than
Temovate. The listed ingredients are:([activated]zinc pyrithione, sodium
lauryl sulphate, isopropyl myristate, and propel 45 (propellant)).Of course,
I am a natural skeptic and I am happy to announce that we have initated a
60 patient, double-blind, vehicle-controlled study to properly evaluate the
effectiveness observed in our case reports. (Our research is funded by an
unrestricted educational grant from Cheminova, - we have no additional
conflicts of interest concerning the product). -I am also giving a talk at
the 1997 American Academy of Dermatology Annual Meeting[San
Francisco, March 21-26], Clinical Research Symposium entitled "The
Successful, Safe and Highly Effective use of Topical Zinc Pyrithione in the
Treatment of Psoriasis: A Report of 10 Cases". (see page 81(second
column, time:3:24) of the 1997 program for details). I've got some
tremendous before and after slides and I encourage you to attend the
presentation and make comments/questions. If possible, I will also
submit new case reports to the " Dermatology Online Journal " for your
review. I sholud also mention that I have recently become aware of
anecdotal reports that the spray, applied twice per day, above the nail
matrix, effectively treats psoriatic nail pitting(as the nail grows out)!!!!!!
We have decided to incorporate this into our clinical study! I have also
used Skin-Cap to treat other pruritic/inflammatory conditions including:
lichen planus, lichen simplex chronicus, atopic derm, severe scalp seb
derm/sebopsoraisis, pityriasis rubra pilaris, and notalgia paresthetica
with equally effective results!!!! It is acting like a topical NSAID and very
strong anti-pruritic!! If additional testing confirms the effectiveness of
this product, it truly could represent one of the major advances in
dermatologic therapeutics since steroids. Currently, most patients have to
pay for it out of pocket (~$39 for 100 grams, -Dovonex retails for about
$150 per 100 grams) The nice thing about the product is that it comes
with a money back guarantee, unlike most Rx meds.

Charles E. Crutchfield III, M.D.
-----------------


I am very interested in this product as well, and have been
happilysurprised to see that it seems to work, when similar zinc
prythioneproducts, such as Head and Shoulders shampoo does not seem to
have thiseffect. You mentioned chromatographic studies. Is the company
willing to allow youaccess to records that might disclose anything else
about the ingredientsin this product? Why should this product have an
effect that other similarproducts do not?I remain skeptical and am a bit
concerned about your enthusiasm. It isimportant to maintain a
dispassionate approach to the testing of anyproduct, especially if the
funding is from the company that makes it. I must admit that your
inclusion of a telephone number in your note soundsa bit like an
advertisement.As regards the comparison to Dovonex, it is my experience
that a 100gm tubeof Dovonex goes a lot longer way than a can of
Skin-Cap. Perhaps spray andointment applications cannot directly be
compared. Additonally, incomparison to other products containing similar
substances, Skin-Cap seemsgreatly over-priced.Having said this, I look
forward to any well done study that might give memore information about
whether this product has true therapeutic value.

Jerry Eisner
----------------


My results parallel yours, and I am excited that you are working
onobjectifying these anecdotal responses. I agree Skin-Cap appears
tooutperform Temovate and Dovonex.

<< The listed ingredients are:([activated]zinc pyrithione, sodium lauryl
sulphate, isopropyl myristate, and propel 45 (propellant)).>What are the
concentrations and what is the difference between "activated"zinc
pyrithione and non-activated? Is activated zinc pyrithione availableto
pharmacists for compounding?

I called the toll free number given here for "Skin-Cap" (888 6 SKIN CAP)
and got an answering machine message that said it was for "dermatitis". I
left a message, first as a dermatologist, that I'd like to get some. There
was no response in 2 days time. I called again as a layperson, again with
no response in 2 days. I then got the local number and address in Miami
from the information operator for Cheminova America. The first time I
called I got an answering machine message that did noyt identify who or
whom I was calling, but said that I should leave a message and they would
call back, which that have yet to do. The local, Miami, number for
Cheminova is 305 825 7008; the local address is 6073 NW 167th Street,
Miami FL 33015. I may try to visit if I get an extra half hour to waste.

Michael Fetterman
----------------


The toll free number that I have been giving to patients is
888-469-7546. They seem to be getting a good response at this number.
I have now suggested this for 4 patients, including a physician. All
have had dramatic responses. I'll be happy when I see a controlled
study. It sounds too good to be all placebo/ moisturizing effect... I hope
it doesn't turn out to be just the latest "fish oil."

Mark Crowe, MD

Has anyone had any positive results with Skin Cap spray? I recall
someearlier discussions on the list a few weeks ago regarding this. I had
apsoriasis patient recently who has tried PUVA, MTX, Dovonex,
topicalsteroids, etc. who elected to go to Memphis to Dr. Rosenberg for
hisantimicrobial treatment (antibiotics + Nizoral + Nystatin). This
patientwas only minimally improved on the regimen, and flared when he
tried todecrease his methotrexate dose. When I spoke with Dr. Rosenberg
about this,he mentioned that he was seeing good results with Skin Cap
spray - in factenough that his psoriasis clinic had been cut in half due to
the success ofthis OTC product. I have started a few patients on it but
have not yet seenthem back. It has to be ordered through the mail from an
800#. Has anyoneelse had success or failure with this product?

Mike Crowe, M.D.

I have been selling Skin Cap Spray in my office for about two months.
Eithermy patients are conspiring to delude me or this is the most
effective topicalproduct for psoriasis that is available in the USA at this
time. Once theyfind out how effective it is, patients never again complain
that theirinsurance won't pay for it. I see patients regularly who had
disappointingresults with PUVA, Tegison, and any topical you can name,
who are clearingdramatically with Skin Cap alone. It is orders of
magnitude quicker thanphototherapy, and I really think it ranks second
only behind methotrexate andcyclosporine in effectiveness. I am usually a
skeptical therapist, andhave never in 20 years felt this degree of
enthusiasm for any new therapy,excepting when Accutane became
available for acne......Try it if you don'tbelieve me. I have no financial
interest in this product, except as adispensing physician. In fact, I
anticipate losing a fair amount of incomefrom patients who will no longer
need phototherapy. We sold a can one Fridayafternoon to a 25 year old, a
15 year veteran of psoriasis therapy. She waswaiting on our doorstep
Monday morning bouncing with excitement and eager toshow us how the
Skin Cap was already working better than everything she hadever tried
after just 60 hours. You can order the stuff wholesale fromInterstate
Drug Exchange and save your patients the hassle of getting it bymail, and
you can save them a few bucks in the process.

Mark Valentine
----------------


I've been reading the messages about this stuff for quite some time, both
with amusement and bemusement.I just had a patient come back from
Mexico, and his widespread psoriasis is spectacularly better now that he's
using Skin Cap. He's certainly better then the anthralin, Dovonex, and
topical steroids I've prescribed ever got him! He's convinced it's this
product, and not the anthralin and Mexican sun, that made him so much
better. We'll see.

Robert I. Rudolph, M.D., FACP

I'd be interested to know the serum zinc levels of people treated with
SkinCap - if there is enough inhaled or taken up through the skin the serum
zinccould perhaps reach toxic levels.

Kevin C. Smith MD FRCPC
-------------------------


Hope I am not totally wrong, but the thing is called Capsoft here. It is
produced by a rather small company in Hamburg. About one year ago, they
had a big scene in a quite popular TV talk show. There, the Capsoft fans
(and the company for sure) complained that no medical center was ready
to perform clinical trials without getting paid for that. On the other hand,
on my request they just sent one specimen, so I couldn't make experiences
with this magic product. And who would recommend the patients to buy a
rather expensive spray instead of prescribing a conventional drug for
free?Hans J. KammlerJena, Germany, LazyEuropeI have their address and
phone no. at the office and will post it tomorrow if no one else posts it
sooner. The latest study I read was in The Townsend Letter, an
alternative healing journal, and I believe was written by a Vet. I can
getreprints or more info if anyone desires--I have not used this product to
date.

I had my pharmacist mix up a number of different formulations ofzinc
pyrithione. The next step is to see which one works. If oneconsiders
azeleic acid: It only works if the mitochondria arefuntioning. On can prove
this in bacterial cultures by adding sodiumazide (which kills
mitochondria) If one adds sodium laurel sulfate tothe bacteria nothing
happens. If one adds azeleic acid nothing happens.If one adds them
together the bacteria should lyse (as they do incultures not treated with
sodium azide) Again nothing happens. Thisshows azeleic acid is actively
transported into the cells, sincestopping the respiratory machinery stops
its action. I realize theazeleic acid analogy is odd here but the take home
lesson is that thereis probably an interaction between the zinc pyrithione
and one of theother ingredients, rather than a pure zinc effect, just as
there is aninteraction between azeleic acid and the sodium laurel sulfate.
Azeleicacid does nothing by itself. Zinc pyrithione probably doesn't
either.I'll let you know when I figure it out.

Haines Ely

According to the Psoriasis Foundation, the original Skin Cap Spray
containeda steroid as well as ZNP. The steroid has now been removed, and
the FDA isinvestigating the product further. Please, you European
dermatologists, tellus more about the product.

Yelva Lynfield
--------------


The source I found was Progressive Labs in Irving
Texas-1(800)527-9512.I called them today, and their Spray is about $21
(for3.33 oz) to the Doc. The propellant is butane. They stated that they
now have a U.S. version in an environmentally safe pump bottle for about
$12.50 for 4 oz.,so I ordered some to try. The article I read (with
impressive before and after pictures) was in The Townsend Letter, Jan.
97, and written by Morton Walker, DPM, Stamford, Conn. Anecdotally, I
saw a severe psoriatic this am who has been using Skin Cap Spray to one
side of her body for two weeks and with very impressive results--I'ma
sceptic, but will give it a fair evaluation, and report back later.

Walter Yourchek
-------------------


I have a sample of "ecological" Skin Cap from Cheminova U.K. Ltd.
Customerservice 800 61 spray (77729)It has 2 mg zinc pyrethrone and 1
mg methyl ethyl sodium sulfate per ml. "forrelief of itching, irritation,
redness, flaking and scaling associated withskin conditions." No mention
of psoriasis. No advice about how often itshould be applied.

Kevin C. Smith MD FRCPC
------------------


I have yet to have any patients tell me about it.However, another
dermatologist in the group had several patients with good response to it,
and about twice that number who failed to respond to it(so he tells me).A
lot us us will be at World Congress in Sydney, where presumably we'll
hear about anything remarkably good and new.

Michael Fetterman
------------------


While this is clearly belaboring the point, I still want to keep talkingabout
Skin Cap. I too have now had several patients return/call withglowing
reports, including two who were on systemic therapies and are nowoff
them, and reportedly clear (in one case, truly clear, confirmed on
myexam). I of course see my professional career treating and
researchingpsoriasis vaporizing as Skin Cap revolutionizes dermatology. A
couplequestions are raised:1. If this stuff is really so good, and has been
available in Europefor a decade, why don't European derms talk about this
stuff??? Do they know something we don't about toxicity or efficacy, or is
this a conspiracy to deprive patients of a drug which would cut their
practices by 50%? (see Dr. Crutchfield's original post in which he states
it'seffective for LP, LSC, atopic derm, seb derm, etc etc). I wish we could
get more feedback from Europe: anyone visiting over their soon?2. If it
truly is this good, I believe this represents a pharmacologicalparadigm
shift which would be equivalent to proving that homeopathic remedies are
indeed effective. Mind-boggling to claim that zinc pyrethione can do all of
this.3. It also would essentially negate the unbelievable volume of
research into diseases such as psoriasis, as it is hard to believe a simple
productlike this works through traditional immunological or
microbiological mechanisms.Keep me in touch with any comments or
experiences you all have with this stuff, directly or via the list. Thanks!

Mark Ling, M.D., Ph.D.
--------------------


Mark, Our friend and semi-guru, Al Kligman, says that everything works at
least once in dermatology. That may be what's going on here. It is hard to
believethat ZPT in teensy concentrations would not help dandruff (look
what happenedto the effectiveness of Head & Shoulders when P&G lowered
the conc of ZPT)but would clear psoriasis.

Guy Webster
----------------


Mass spec or NMR would be dandy, but liquid chromatography cheaper and
more readily available in any highschool chem lab.I'd suspect something
like that, but even so, TCA in my hands is no miracle drug.

Michael Fetterman
-------------------


Also have had a couple of psoriasis patients come in with
"glowing"reports of clearing with Skin-Cap-one in particular claimed to
have required mtx in the past, but now controlled with Skin Cap. My
response was to provide a sample of DHSshampoo with Zinc(label states
contains 2% ZNP) and to compare.Patienthas not returned so I'm assuming
complete satisfaction.

Pierre Jaffe, MD
-------------------


Just opened my Jan-Feb 1997 issue of JGD(J Geriatr
Dermatol1997;5(1):21-4) byCrutchfield et al titled "The effective use of
topical zinc pyrthione inthe treatment of psoriasis: a report of three
cases.Impressive photos depictingsignificant and rapid improvement.
Possible mechanisms discussed.Is itthe zinc? or is it the vehicle?is it the
combination of the above?A funread on a gloomy saturday afternoon.
Pierre Jaffe, MD
-----------------


Would someone with patients responding to Skin Cap please check a few
serum zinc levels and report back to us. I wonder how much uptake the
patients are getting through the skin and by inhalation. Hope there is no
heavy metal or arsenic in the spray (arsenic of course works great for
psoriasis but hasfallen from favor because of a poor long-term side effect
profile).Maybe look for adrenal suppression too - that might pick up an
obscurecorticosteroid derivative that could be missed if you didn't know
what tolook for on the mass spec / gas chromatography.

Kevin Smith
------------


When we discussed Skin-cap, I think I told you that the ZNP bar is great
forseb derm, and that I started to recommend it to psoriatics. About half
adozen of my chronic plaque psoriasis patient have returned for followup
afterusing the bar for a month, and neither the patients nor I was
impressed withits action except as a shampoo.

Yelva Lynfield, MD
-----------------


Read "The Effective Use of Topical Zinc Pyrithione in the Treatment
ofPsoriasis: a Report of Three Cases" published in The Journal of
GeriatricDermatology Jan/Feb 1997 by Chas. Crutchfield et al from the
Univ. of MinnesotaDept. of Derm. In this peer-reviewed journal they
describe dramatic successwith Skin Cap Spray used b.i.d. on one side vs.
triamcinolone oint. or placeboointment on the other. In one case, near
clearing occurred in 8 days. They havea bigger study underway.Like
everyone else, I was surprised but this product does seem
efficacious.They did acknowledge that other ingrediants like the
propellant may be afactor.

Philip Hughes, M.D.
-------------------


I saw a patient today who I have been treating for psoriasis for
severalmonths. He had failed to improve on Dovonex or Temovate or a
combination ofboth and had many inflammatory, eruptive, and pruritic
lesions all over thebody. I started him on Tegison two months ago at a
low dose, 25 mgm daily,and raised the dose to 25 mgm BID one month ago.
Two weeks ago, whilevisiting his psoriatic aunt in Puerto Rico, he was
given a can of Skin Cap. He used it only on the left leg below the knee. The
change was dramatic. The right leg had improved no more than 25% on
Tegison whereas the left legwas completely clear! I don't know how this
stuff works, but it seems towork better than almost anything in our
current armamentarium.

Isaac Novick, MD
------------------


No personal or clinical experience with Skin-Cap, but one of the other guys
in the group says he had several patients show phenomenal clearing of
scalp psoriasis and seb derm with it..but then found that like lots of other
products, was helpful for maybe an estimated third of patients.

Michael Fetterman
------------------


May I hear from anyone who has seen a failure to respond to Skin Cap?
Also, how about side effects? And success in non-classic plaque
psoriasis? The manufacturer claims a success rate of 85%, and I think
this may beaccurate, as I've seen four patients with negligible benefit out
of the fortyor fifty patients who have tried it in my practice, and it is
safe to assumethere are a few more failures out there who have yet to
report back to me.No one has discovered any side effects yet. I intend to
check zinc levels on any patients who are steady users of large
quantitities of the stuff, buthaven't yet had the opportunity. Anemia from
copper deficiency is the only theoretical side effect I am aware of.I
haven't tried it on pustular or erythrodermic cases yet. I have
anerythrodermic PRP patient and a refractory lichen simplex chronicus
patientwho are trying it, but no reports yet on results. I also don't know
how itperforms on palmoplantar areas yet. Scalps respond well to it.
We've sent afew patients home with the pump-spray formulation from
Progressive Labs tocompare with Skin-Cap, but again too early for any
feedback.

Mark Valentine
--------------


I am delighted to see some feedback regarding the Skin
Cap-typeformulation from Europe, where these zinc pyrethione products
haveapparently been available for years. I am still struggling with
theconcept of a product which is 85% effective, according to a recent
post,yet which has not apparently swept Europe by storm. I've given about
40or 50 of my most recent psoriasis patients over the last month info
reSkin Cap so I presume in a month or two I'll have more
substantiveexperience to report. More European comments??

Mark Ling, M.D., Ph.D
.------------------


In Germany there is a product called "Capsoft Regulativ-Spray".I don¥t
know if it is identic to Skin cap, but it containsZink-Pyrithion like this.
Unfortunately I have no personally experiencewith this product, but i read
about it in "Pso Magazin", the journal ofa german psoriatic group. Several
psoriatics write about their badexperiances with Capsoft. They describe it
as skin irritating.Dermatologists of the University of Hamburg saw four
cases withpsoriasis pustulosa after use of capsoft.

Andreas Eisenmann
---------------


It certainly isn't the zinc pyrithione in Skin Cap which makes it work.
Ihave mixed up gels, liquids, and creams with varying strengths of
ZPwithout much effect compared to the brand name stuff. I deleted
themessage about the propellant of Skin Cap spray so I couldn't ask
theauthor to e-mail me directly but I am extremely curious. What is
it?Haines ElyI just got back from visiting Vanderbilt Psoriasis Center.
Nurses statethat results with Skin Cap Spray have been mixed but
generally positive.They state that many patients have been more
impressed with a productcalled Apis. I am getting more
information.Anybody heard of it?

Trey Truett, MD
-------------------


Isopropyl myristate is a synthetic oil found in many cosmetics, and in fact
in some acne topicals, I think! I knew a dermatologist who thought it to be
comedogenic.My money is on the sodium methyl ethyl sulfate, or some
moiety derived from it, as being the (still) secret ingredient. Can anyone
here comment on (potential) carcinogenicity of alkyl sulfates ?

Michael Fetterman
----------------


This might help those of you who are running literature searches:In my
handy Sigma chemical catalog (every derm office should have one - mineis
kind of old - 1988) isopropyl myristate is listed as: myristic acid
ethylester (a synonym is: ethyl myristate).Myristic acid has a synonym:
tetradecanoic acid.In 1988 isopropyl myristate sold for 24.70 / 100 g for
the 99%, and 24.00 /liter for the 95%. Certainly much cheaper in bulk.

Kevin C. Smith MD FRCPC
---------------


Isopropyl myristate is "Liquid Wrench" I think it is also a maincomponent
of WD40. It is the agent which induces perioral dermatitis inmost
makeups sold as "oil free". What a coup! Thank you sooo much forthis
information. Liquid wrench is a lot cheaper! Haines ElyIndeed, I believe
there was a tabloid story a year or two ago about WD40 for psoriasis. I
believe everything I read.

Haines Ely
------------


Don't you believe the zinc has anything to do with it? Will you have
yourpatients put on Head & Shoulders and spray with WD40? (is it really
trueabout WD40 or is this just another "urban" myth?).

Eliot Mostow
-------------


As I mentioned in a previous note I've had my pharmacist mix up
zincpyrithione in every vehicle I can think of with only minimal results.
Imight add, only the solution with added B6 had any effect.

Haines Ely
-------------


Hans, as far as I can see, FK-506 have very different properties. FK-506
works as a topical agent on psoriasis. Cyclosporin doesn'teven work when
injected intralesionally in Psoriasis.

Rhett Drugge, M.D.
-------------------


After noting the possible association between Skin-Cap and WD40, one of
our Rheumatologists told me that many of his arthritis patients spray
WD40 on an inflammed joint and get temporary relief of pain. He believes
it works but also thinks that it may have caused one case of neuropathy.
Today, I recieved my first mass mailing for ordering Skin-Cap. The need
for credible data on safety and efficacy is clear!

John Melski MD
-------------


I hope it is forthcoming. However, I was able to speak with someone at
theFDA dermatology division Thursday, and she wasn't able to tell me
much. Iasked if I might be kept abreast of any investigation into the
safety of SkinCap. Apparently it is strictly against FDA regulations
torelease any information whatsoever about investigations or new
drugapplications that are pending. She was categorically unable to even
discloseif Skin Cap currently has any applications filed with the FDA. My
concernsabout patient safety seemed to not count for much in the FDA
scheme ofthings. She suggested I contact the office on Advertising and
Communicationsand lodge a complaint because of the illegal advertising
for psoriasiswithout an FDA indication. This I am not prepared to do.
Knowing how theFDA works, they would probably determine that it was
entirely safe, and thenproceed to confiscate all the product, since they
value form over function bya 10 to 1 margin.Meanwhile, my first feedback
(one patient only) on the zinc pyrithione sprayfrom Progressive Labs in
Texas is that it is not effective, at least whencompared with Skin Cap.
This is as Haines predicted. I also saw threepsoriasis patients yesterday
who, much to my dismay, failed to see muchbenefit from Skin Cap.

Mark Valentine
-----------------


I recently had a patient in with psoriasis resistant to topical therapies
but as it was not too severe she did not want to try anything else...yes, she
was in last week clear, using skin cap...as her lesions did not respond to
temovate it makes me wonder, despite a biopsy consistent with psoriasis,
if we are not dealing with more than one cause of psoriasis, even though
the clinical/histological pictures are the same...so that type 2 for
example, may be steroid/mtx/etc resistant but skin cap responsive... any
comments?...

Steve Emmet
--------


Well, I've finally bowed to my own curiosity and started to use Skin Cap
Spray. Just a few patients, paired comparisons with one side being
treated in the usual fasion for that patient, and the other with Skin
Cap...very informal, careful observations and phone calls.Preliminary
thoughts...impressive results. Some of the " light patients " with
resistant areas have cleared. The untreated areas, no change. Patients on
Mtx with some residual plaques...cleared on the treated sides, no change on
the other. No experience yet with nail problems, looking for more date on
scalp psoriasis.Continuing to study, more information in a few weeks.

Skin Cap seems to be working ok here in south hemisphere,too. One 75 yr
oldpatient with widespread psoriasis had some control,before,but taking
manydrugs,etc. Like magic, his only 15 days applying S cap has lead him to
morethan 50% clearing - we are all amazed! He complains of the price, but
he'svery happy.Hope you don't find any bad thing about this product.

George Leal
------------

Dear all,one of my psoriatic patients brought me today the insert of SKIN
CAP, newlymarketed in Brazil (supposedly the same). It says- "S Cap is a
modernproduct, made of A TENSOACTIVE (METHYL ETHYL SODIUM
SULPHATE) THAT HASANTISEPTIC AND KERATOLYTIC PROPERTIES
(ELIMINATES EXCESS OF EPIDERMIS IN ALARGER THAN NORMAL SCALE). THIS
TENSOACTIVE RECEIVES A POTENCIALIZATIONFROM ZINC PIRITHIONE, that
reforces ist antibacterial and antifungal actions(alas , decisive for the
control of the affection).I am doing a little research on methyl ethyl
sodium sulphate, but so farunproductive.

I have received the following communication from Richard Faiola,
M.D.,Medical Director of "Noble Products, Inc." a Distributor of Skin Cap in
theU.S. According to the letterhead he is a family practice doctor
andmanaging partner of L.G. Steck Memorial Clinic in Chehalis, WA.

To: WHWoodII@aol.com
Per the manufact. they have appropriate registration with FDA and
anational drug identification # (its on the package). FDA "approval" of
aspecific product like SkinCap is not required and has neither been
soughtnor granted. Its ingredients are from among those for which the
FDA haseither granted a "generally recognized as safe" designation or has
apermissive "monograph" on. In other words, manufactures are free to
usethe ingredients of Skin Cap without specific additional FDA review. It
isan OTC product. It does not require New Drug Application,
norsafety/efficacy data when labeled for the cosmetic indications
of"Dandruff" and "Seborrhea." They can not label it for the
medicalindication of "psoriasis" The FDA removed "the heartbreak of
psoriasis"from the cosmetic to the medical several years ago. That does
not mean Ican not share with me colleagues its utility for symptoms
associated withthat disease, but our consumer advertising will be careful
to make clearthat it is for the symptoms of "itching, flaking,
inflammation" associatedwith various skin disorders. A double blind
placebo controlled study isbeing completed in now, by an American
researcher, independent of thecompany. I believe, but have not first hand
confirmation that the resultsare confirmatory. The researcher had a bit
on the Internet 2 or 3 weeksago, responding to a question, and reported the
results as promising andalso that he expected to be presenting to the
Derm meeting in SanDiego. The company sponsored some studies in Latin
America--I have reviewed them. They showed good results, but they do not
meet my own or usual scientificstandards. The active ingredients are
those listed in my letter. ZincPyrithione, sodium laurel sulfate (an
irritative detergent in toothpasteand several other hygiene products.
There is some alcohol and otherpresumed inactive excipients and
propellants. The zinc portion is, ofcourse, the same as in "Head and
Shoulders." I personally believe the SLSfacilitates the absorption of the
zinc, while acting as a directkeritolytic (SLS has been shown to permit
the dangerous absorption ofnickel transdermally in foundry workers, no
known studies directly on zinc,but then unlike nickel zinc is a desirable
nutrient). Bottom line: Thestuff is relatively cheap compared to some of
our other options, looks likeit should be reasonably safe, and IT WORKS.
About 50,000 persons are orhave used it in the US

i have a very cooperative japanese patient with basically total body
psoriasis, untreated, (mentioned as i don't know if japanese skin may
respond differently from caucasian)...who used skin cap bid on one arm and
temovate cream bid on the rest of his body...at three weeks of temovate
and two weeks of skin cap, the skin cap was clearly better, with flatter
plaques, less redness, less itching....

CLEARafter one month, and 6 cans, of Skin Cap aerosol. No kidding.IWe will
see if it will be the second non-prescription drug put on theformulary. The
first being Unibase.

A few weeks ago I suggested to a half-dozen psoriasis patients that they
tryLiquid Wrench on their psoriasis ( eg. Wal-Mart, $4.99, mostly
isopropylmyristate) and the first one came back yesterday -- happy lady:
not amiracle, but considerably improved.

Another glowing report for Skin cap spray here also........56 yo
recalcitrantpsoriatic who we have been keeping maintained with modified
Goeckermantherapy, topical steroids and dovonex. One week and two
bottles of skin capspray and she is TOTALLY CLEAR...........I am impressed!I
have just place 5 more patients on it and will report later.

... personal experience. I've given SC to between 50 and 100 patientsover
the last two months. My experience is that it is an unbelievablyeffective
drug for a SUBSET of patients, perhaps 50% in my estimation.They get
dramatic clearing, often within a few days of starting, andwithin a month
generally are to the point where it's tough to see wherethe psoriasis used
to be. Phenomenal. Others simply don't respond, or evendevelop a
significant irritant dermatitis. I worry about the stuff a lot,since I don't
believe it's just another Head and Shoulders, but it is soeffective that at
least until someone demonstrates potential toxicity itis hard for me to
justify not using it. Still, I'm keeping my ears open.The demand is so great
now that the Nova folks are 4 weeks back ordered.Finally, I had some
patients try a "knock-off" in a pump spray bottle. Wassupposed to be just
as good as SC. It was 100% ineffective, a totalfailure. BTW, the local
distributor, a former patient, apparently admittedto one of my current
patients who had tried the knock off, that he hadbeen forced to start using
"real" SC again to control his psoriasis

I understand that there is good efficacy and tolerability in early
trialswith calcipotriol (know as calcipotriene in the US) in an isopropyl
myristatebase for scalp psoriasis.Isopropyl myristate is of course the
same stuff found in Skin Cap. It is saidto greatly enhance permeability of
the scalp to calcipotriol.

Kevin C. Smith MD FRCPC
----------------------


the steroid rumor has surfaced with Skin-Cap repeatedly: I think
thearchives may contain prior discussion. Dr. Crutchfield at U. Minn. has
hadit analzyed with GC and clearly states there is no steroid peak
identifiable. That of course does not mean that Skin-Cap might not cause
striae.

Mark Ling, M.D., Ph.D.
--------------------


For those who may have missed out on the earlier discussion, Skin Cap is
anOTC spray product that contains zinc pyrathione (the stuff in Head
&Shoulders shampoo) in an organic base that is largely isopropyl
myristate.Apparently this base is important for allowing penetration of
the zinc tothe deeper layers of the epidermis. This product is
manufactured byCheminova International Laboratories and distributed in
via the Internet byNet Nova Pharmaceuticals
(http://www.clearskin.com/).The spray works dramatically in somewhat
more than half of patients withplaque-type psoriasis when sprayed on bid.
An interesting facet of it isthat the severity of the problem doesn't seem
too much of a factor inwhether someone will be good responder or not,
meaning it may work on someof your severe longstanding problem
psoriasis patients that don't respondwell to much else.I know it sounds
like a con game, but it is true. When it works it's betterthan Temovate
(works faster too) and (so far) doesn't seem to have thetachyphylaxis
problems of topical steroids.

It is cheaper to buy in largequantities, so if you are going to start
recommending it, you might do yourpatients a favor by being their volume
purchaser and reselling it to themat near cost.The toxicity of this
preparation has not yet been studied very well,although Zinc is one of the
least toxic metals (compared with Cadmium,Mercury, Arsenic, etc.), and
has even been used orally to treat a number ofdiseases in the past
including Wilson's disease [1-3], cirrhosis [4], andsickle cell anemia [5] to
name a few. Dermatological diseases that havebeen treated with it include
acne (doesn't really work very well) [6-10],chronic mucocutaneous
candidiasis [11] and interestingly enough, psoriasis[12]. Before you all run
out and put your psoriasis patients on oral zincsulfate, please note that
this double-blind trial with 25 patients wasunsuccessful. 600 mg/day of
oral zinc sulfate is fairly well tolerated withmainly GI side effects, so I
am assuming for the moment at least that thisSkin Cap stuff is not going
to be too toxic. As well as it works, it's notgoing to go away unless it
turns out to be a lot more toxic than Ianticipate, however. Somehow this
got by the FDA, I suppose because zinc pyrathione had been around and
shown to be safe (Head & Shoulders shampoo).However the Cheminova base
is a whole 'nother ballgame and turns zincpyrathione into a sure 'nuff
potent topical drug. Stay tuned.

this is an updated report. The patient is the "elevated sgpt
psoriasispatient",presented in these lists weeks ago, to whom I started
SKIN CAPSPRAY. I AM COMPLETELY AMAZED!!!!!! ASTONISHED! - with just one
week of thespray use, he GOT RID OFF ALL HIS LESIONS, SCALP AND BODY!!!!
I saw himtoday,he is completely "clean", and we are all very happy! And he
hasn'tapplied it for 2 weeks.We are also happy he doesn/t have to take Mtx
(or anything else),so far.I hope this thing doesn't cause tachyphylaxis,or
anything else, for it wasfantastic. I have some other patients using it,yet
to come back.Thanks

George Leal

Dear Drs. Crutchfield,
I have had an excellent success with the few patients to whom I haverx
Skin Cap Spray. Now I ask you, once achieved this result, how do
youprescribe maintenance therapy? I have told them to apply the spray
once aweek, in the places that had the lesions before. Have you seen
tachyphilaxis?
George Leal

Skin cap spray has produced an acneiform eruption in several of my
patients whenused on the face or neck. Not surprising after all the talk
about commoningredient in WD 40, Liquid Wrench and Skin Cap Spray.

Philip Hughes, M.D.

Diane - there is a primary irritant contact dermatitis that occurs from
timeto time with skin cap - I've seen it in one caregiver who developed
itwithin 48 hrs on forearms where some of the mist settled - cured by
usinglong sleeves and greater care.Other notes on Skin Cap.Local WalMart
now has it behind the counter - too much stock "shrinkage"from folks
taking a five-finger discount. How many little cans could you fitin *your*
pocket or purse? The sign of a successful product, I guess.Helpful
money-saving hint. Spray a bit on a china saucer, use a finger toapply dabs
quickly to areas you don't want to spray ( e.g. spots on face orguttate
lesions or even the returning spots when the disease wants to comeback).
If worried about contact, wrap applying finger in SaranWrap then dipand
dab.I have now treated three DLEs (BID x 2-4 days then 1/day x a few days
thewait and watch) and two non-specific intertrigos in males (single
spraytwicw a week only - done in the office for good control and so I can
watchcarefully the results.

I now have one patient with extensive psoriasis who is using Skin Cap
insome areas & Liquid Wrench in others. She feels there is some efficacy
ofLiquid Wrench & she reports that both products have an identical feel
onthe skin. However, the Skin Cap appears to be the more effective
product.

I have had a number of patients develop acneiform eruptions (acne
venenata) from Skin Cap Spray, which isn't surprising.

Philip Hughes, M.D.
-----------------


Just an update on my experience with SkinCap. I stock it so as to provide
my patients with their first can ( charge $30). I have arranged for a local
pharmacy to carry it and ask pts to get more there. I explain that I do not
know why it works, and despite lack of knowledge about all the
ingredients, have not heard any significant comments from those on this
list about serious side effects.The patients are uniformly reporting
favorable effects on scalp, body and hands. I have not seen any significant
side effects, except for a little dryness in some cases.

Jerry Eisner

I've been following the Skin Cap discussions with interest, and
havepurchased some and am now having some patients use it. These are
allpatients I've seen for years, and who have resistant psoriasis.
Theseare the kind of patients we all have a lot of: good patients who
havetried many therapies (of all sorts, including the "big guns"), and
whoremain active, and difficult to treat.I just got a marvelous letter from
a young man with very widespreadpsoriasis who tells me his psoriasis is
better now (after one week) oftherapy, then ever before.I asked him to
come into the office, and guess what: he's spectacularly better. I have
never seen any response in any psoriasis patient like this in 22 years of
practice! Ican't wait to hear from other patients. I'll let the group know
about the follow-up. As for now I stand amazedand delighted!Had another
lady come into the office to show me the effects of Skin Capon her
widespread and very chronic scalp psoriasis (which has notresponded well
to topical steroids, tars, acid preps, etc. over theyears).After 5 days of
use she is clinically almost totally clear of PSO. She and I are pleased
andastonished.

Has anyone seen (not heard of) any significant untoward reaction that
they believe is more likely than not due to Skin Cap? I have not seen any.
Jerry Eisner >>So far naught but an occasional complaint of stinging in
over 225 canssold.....One of my most impressive responses: A man with
severe pustular psoriasis ofthe hands, with marked swelling, secondary
anonychia, and inability to evenbutton a shirt or zip a zipper, had been
completely disabled by his diseasefor at least 8 years, and essentially
unresponsive to MTX, PUVA, topicalsteroids, and Dovonex. Symptoms
reduced to mild peeling with two cans ofSkin Cap......

In response to the question of adverse reactions to Skin Cap: We (I and
Drs. Lewis and Zelickson) are currently conducting a 60 patient double
blind, vehicle controlled study on the treatment of topical zinc pyrithione
spray (skin cap) for psoriasis. We published the results of pilot studies in
the Jan/Feb issue of the J. of Geriatric Dermatology (they accidentally
reversed the before and after photos-so please "reverse them back" if you
read the article), and recently spoke at the clinical research symposium of
the American Academy of Dermatology (San Francisco, 1997) and
presented at the Society of Investigative Dermatology (Washington DC,
1997) and have a published report that can be viewed on the Dermatology
Online Journal;web address:
http://matrix.ucdavis.edu/DOJvol3num1/zinc/zinc.html Essentially, in our
clinical experience of well over 100 patients, in about 5-10% of patients
we have seen a very mild and transient flare of the psoriasis that falls off
in the first 1-3 days. I warn my patients about this and tell them to treat
through it, unless it becomes severe (which it has not, as of yet). About
20% of patients complain of dryness and/or irritation. For the dryness, I
recommend a moisturizer of choice about 1 hour after applying the
Skin-Cap. For moderate to severe irritation, I recommend just QD
applications. I have had 1 or 2 clinical patients stop using due to
irritation. None of the study participants have left the study for adverse
reaction reasons. There is a post healing erythema that is replaced by
post-inflammatory pigmentation that fades with time. Although I have
not personally seen it, I have heard of reports of tachyphylaxis-like
reactions from colleagues. Additionally, there have been reports by users
on the psoriasis support groups of what they term as a "rebellious
psoriasis", i.e. red papules and possibly pustules arising at the periphery
of healing plaques. The only explanation that I have for this, (since I have
not personally seen it), is a koebnerization reaction secondary to
irritation of normal skin included in the "treatment spray area". I have had
a few patients who have significant improvement to a point, but don't
totally clear. The next time this happens I'll be tempted to try
combination therapy (add a potent steroid or Dovonex, or both). I have not
tried combination therapy to date, but this may be a good group to try it
on. Has anyone else tried combination therapy? I have seen a small group
of patients who, with compliant BID applications, don't start to respond
until week 5 or 6. For this reason, I don't consider anyone a treatment
failure unless they have compliantly adhered to a BID application for 8
weeks.We'll have more to say as we conclude the study (August 1997)and
analyze the results. We are also looking at the treatment of psoriatic
nails by BID applications above the nail matrix, and also looking at
periodic, treatments (once or twice per week) to cleared "trouble areas"
to reduce or prevent future flares. We are also initiating cellular studies
with Mark Pittelkow at the Mayo Clinic to get a better understanding of
the cellular mechanisms of action.What are others experience with the
tachyphylaxis/rebellious reactions??? I donít know if there is a "safe"
limit to the surface area that can be treated. Cost seems to be the
limiting factor at this point.Has anyone had any luck treating palm/plantar
pustular psoriasis?? I've had a good response in 1 patient of 2, with a 3rd
patient being evaluated currently.What about keratoderma
blennorrhagicum? (I haven't tried it on this condition, yet). I have also
used it very successfully on lichen planus: 4 of 4 patients with near to
total clearing, with a 5th patient being evaluated currently.I understand
that there will be several other "knock-off" zinc pyrithione sprays
available soon. I'm happy to hear of this, especially if they work.
Competition is good, and hopefully will drive the price down, a complaint I
constantly hear from my patients who have to pay the OTC price of $30-40
a can, and who can easily go through several cans to gain control.I enjoy
reading about the experiences of others, good and bad, of this interesting
treatment. Iíll share additional information concerning our research,
with the group, when appropriate.

Charles Crutchfield III, MD

The isopropyl myristate of Skin-Cap is a proven comedogen. However that
does not make it "the mechanism". It is fairly well proven, I think, that the
major route of penetration of topical agents is via the follicles however.If
we can assert that zinc pyrithione under occlusion is capable of this
dramatic result in psorisis and other inflammatory dermatoses, then it
would be a cheap study to see if topical zinc pyrithione and other
comedogens or occlusive dressings do the job.I doubt it.Certainly the
isopropyl myristate content along is basis to avoid acne prome regions.

Michael Fetterman

I have been using Skin Cap for several months and so far the results
areremarkable. In my opinion Skin Cap blocks a step very high up in the
cascadeof events that gives rise to a psoriatic plaque and thereby stops
the wholeprocess cold. All the other medications we use act to suppress
psoriasis atthe end of the cascade. When we find out how it works we
will probablyuncover something very basic in the pathogenesis of
psoriasis.I order Skin Cap in bulk from Acu-Derm and sell it to patients at
cost. Itell them that if the medication works they can order it
themselves. Thetoll-free number is on the box. Do I feel bad about giving
patients a medication of whose mode of action I amignorant? No, because
the vast majority obtain quick and complete relieffrom a bad disease that
I have not been able to give them using variousexpensive medications all
of which have their own set of side effects. Idon't think I could, in good
conscience, start a psoriatic patient onTegison, Methotrexate, PUVA,
Cyclosporin, Hydroxyurea, or even UVB withouttrying Skin Cap first.

Isaac Novick, MD
------------------


I just wanted to alert the members of some information I became aware
of last night. According to an article published in De Telegraaf, May 29,
1997, the Minisrty of Health of the Netherlands pulled Skin-Cap off the
market because it was discovered to contain a potent steroid. Early in
1996, Skin-Cap was banned from the Austrian market because if was
found to contain high levels of triamcinalone (~0.5%). I received the
Austrian information from a posting to a psoriasis support group by the
Canadian Distributor of Skin-Cap (her name is Patricia Cross, email
address:pcross@rideau.carleton.ca). According to an official cheminova
company statement, a few lots were accidentally "contaminated" with
triamcinalone. They were unsure how this happened and plan to try to
reintroduce it back into the Austrian market sometime in the future.
Concerning the Netherlands- Recently, a high ranking official at the
National Psoriasis foundation did telephone and speak with an official at
the Ministry of Health in the Netherlands who was involved with the case
and was told that the steroid found was clobetasol proprionate!We are
currently finishing a 60 patient, double blind, vehicle controlled study on
the use of topical zinc pyrithione (s. cap) to treat psoriasis. Naturally, we
were concerned and very interested in this development. Because of early
rumors of steroids(which recently went fom rumor to fact by the
cheminova/Canadian statement) , we did test the study samples for
triamcinalone (HPLC and nmr) and found NO triamcinalone. It is my
understanding that it is very difficult to detect any random steroid- it
must be looked for specifically, a time consumimg and costly fishing
expedition if one is to be thorough, which certainly was beyond the scope
of our study. The company stands by its statement that U.S. Skin-Cap
contains only: zinc pyrithione, isopropyl mysristae, propel 45 (iso-butane)
and sodium-lauryl-sulphate (although initally they claimed that the
sodium-lauryl-sulphate was "sodium-methyl-ethyl-sulphate", a situation
which is still confusing. I have sent a letter (fax) to Cheminova today
(June 13, 1997) asking for an explanation of the Netherlands events and
to, once again, confirm that the U.S. product does not contain steroids of
any kind. Has anyone seen immediate blanching, steroid atrophy, or
tachyphylaxis-like reactions in s. cap patients? I have not, (but I have
heard of a few tachy reactions).Does anyone else have any insight into this
interesting situation? I will keep the group updated on the response and
any additional information that I come across. We will now try to check
for clobetasol proprionate, as I am sure others (FDA, etc) will also.

Charles Crutchfield
-----------


I'm sure all dermatologists have prescribed triamcinolone and clobetasol
for a dozen years or more in the hopes of containing and trying to "cure"
psoriasis. Has it ever worked? Has it ever worked like Skin-Cap? Never!I
have, as we speak, discharged 14 psoriasis patients, some of whom have
had their ailment for more than 30 years. I either have discharged them, or
they call me and tell me they are cured. And they thank me and some say
they pray for me. And these same patients have used, on and off, all the
potent steroid creams, ointments, lotions, and sprays, including
clobetasol (Temovate -- cream, E-cream, ointment, gel and scalp
application). With little, if any, significant results.So if there are a few
"drops" of clobetasol in one (or more) of these sprays, how do you account
for the almost immediate relief -- subjective and objective -- of
psoriatic patches? And thick scalp psoriasis? And you all have used
clobetasol, haven't you? Have you gotten similar results?There has to be
another answer. Meanwhile, I'm happy that many of my patients are happy
with their results.

Jerry Litt.
------------------


I can only say that I have never had the results with clobetasol,
Dovonex,methotrexate, whatever, that I am seeing with Skin Cap.I have
used it successfully on dyshidrotic eczema of the hands that wouldnot
respond to clobetasol.I most recently am using it on an elderly woman
with intertrigenouserosive and pustular psoriasis. I believe the acute
episode was triggeredby her diabetes,indwelling urinary catheter with
infection, and possibly yeast. She wasinsevere pain from the erosions and
we placed her in the hospital. I amapplying Skin Cap once daily in this
area. I am also using Tegison 25mg,IVCipro, oral Diflucan, and topical
Desonide (once daily). Within 24 hoursher pain was resolved. Within 48
hours her pustules are resolving and theerythema fading. Whatever is in
this stuff, the benefits outweigh therisksso far. The patient thinks I
perform miracles. Keep us posted.

Jerry Eisner
------------------


I agree with Drs. Litt and Rudolph, I've never seen anything work like
skin-cap. Including our study, Iv'e used it in well over 100 patients with
only a handful of failures. I've used it against psoriasis (monotherapy
and combination therapy with the residual plaques of MTX and PUVA),
lichen planus (ESPECIALLY LP-see previous posting), atopic dermat
