New Botox Available in US in September 2010

A new type of Botox called Xeomin (Merz Pharmaceuticals] will become available in the US in September 2010. The drug was approved by the FDA in August 2010 for treating certain neuromuscular conditions, such as blepharospasm (chronic blinking), cervical dystonia (tight neck muscles that distort the head's position). It is not yet approved for cosmetic purposes to treat dynamic wrinkles between the brows and on the forehead. Such use would be considered off label but Botox was used in such an off label fashion for years before it received FDA approval for cosmetic use.

That means we will now have 3 products available, Botox, Xeomin and Dysport to treat aging wrinkles of the face. More Dysport has to be injected to get the same results as Botox but since the per unit price is cheaper the end cost to achieve a given result is the same for Botox and Dysport. Xeomin is formulated differently in that it does not contain the complex proteins found in the other 2 formulations. It is too early to say if this is a positive or negative attribute. It could lead to migration of the Xeomin away from the injection site with more side effects or it could mean you will not form antibodies or develop resistance to the medication after many injections.

Since the price of Botox did not change after the introduction of Dysport is likely those prices will not change after the introduction of Xeomin. That may be due to Dysport's failure to steal market share from Botox but only time will tell.
