Mentor Getting a FDA Approval on Botulinum Toxin Type "B"

Dear JulieKokesch Mentor's product is also a Botulinum toxin A product just like Allergan's BOTOX. There is currently a Botulinum toxin B product on the market and this is called Myobloc and it is marketed by Solstice Neurosciences, Inc. Myobloc is primarily used for medical indications particularly for neck pain and muscle spasm in individuals who have developed resistance to Botulinum toxin A.

PureTox is the brand name for Mentor’s injectable botulinum toxin type A. Its applications will be similar to Botox® for wrinkle correction and muscle relaxation, etc. It is anticipated to become FDA approved and available in the USA sometime in 2010. I hope this helps.

Botox, Reloxin, Purtox, and Xeomin are all Botulinum type-A neurotoxins. While Botox is currently the only FDA approved Botulinum toxin in the United States, the other toxins should be approved soon. Reloxin and Xeomin are approved and being used in Europe. Interestingly, Purtox is a "naked" type-A botulinum toxin - meaning it doesn't have complex proteins around it. This may be the reason that it appears to have a faster onset compared to Botox.

It is difficult to anticipate or have any definitive knowledge of when Purtox is approved. These issues are highly guarded by the FDA for no apparent reason other than control.

Hi Julie, As of two weeks ago at The South Beach Symposium, there was still talk of the "soon to be FDA approved " Mentor product, but no one had an accurate estimate. I am sure that we will all know when it recieves FDA approval. There was a lot of buzz about the new topical Botox products, also awaiting FDA approval. Be well. Dr. P

There are actually 7 types of toxins from clostridium, but only type A is used for cosmetic purposes, so all of the products in that category are variations of that. There is one type B, called Myobloc, which is cleared for theraputic use. Mentor's type A, Called PurTox, is expected soon but who knows. Merz Pharmaceuticals, which just acquired Bioform (the maker of the filler Radiesse) also has one on the market in Europe so they may have plans to bring that to market in the U.S as well.... more
