PurTox like BOTOX with it
being made from a strain of Type A botulinum toxin. PurTox is not as yet
approved by the US FDA, and is currently in phase 3 testing for
as well as medical/therapeutic indications. It is anticipated that PurTox will
be used to treat facial lines and wrinkles that result from underlying muscle
activity much like BOTOX.
PurTox gets its name
because the company finds it “pure” with not having any surrounding
hemagglutinin protein complex.
PurTox, like Dysport and
Xeomin has a higher
of human serum albumin.
The studies are still being conducted on this new toxin, and so far the
efficacy, safety and longevity all appear to be very similar to BOTOX. From the
studies done so far, PurTox seems to show a slightly earlier onset when
compared to BOTOX.
Puretox, a third competitor to BOTOX, is expected
to hit the market in the spring of 2010.
