What is Dysport ?
Dysport is the latest neuromuscular blocking agent available. The generic name of the medication is abobotulinumtoxinA. Dysport is a direct competitor to botulinum toxin type A, trade name Botox(r). While there are technical differences between the two medications, the base content of both is botulinum toxin type A which causes paralysis of muscles by blocking the transmission of the chemical agent acetylcholine which tells muscles when to move. By paralyzing certain muslces of the face, the overlying skin wrinkles can be relaxed and wrinles produced with muscle motion will be reduced.

Dysport was approved for use in the United States in 2009 though it has been in use in other countries for several years. Dysport is approved for cosmetic use to treat the lines between the brows, the glabellar furrows. It is supplied as either a 300 unit or 500 unit vial and requires reconstitution. The doseage of Dysport is different from the dosing for Botox. The suggested starting dose for treatment of glabellar furrows with Dysport is 50 units as opposed to 20 units for Botox.

Botox vs Dysport
Both Dysport and Botox have the same active molecule, which is the toxin that causes botulism (in dramatically higher doses.) It is a protein that is encased in other non-toxin proteins, so the difference is that Dysport has fewer of these so it is a smaller molecule. What this means in practice is that it spreads a little bit more and may take effect about a day sooner. In some areas, there is a softer transition from the affected area to the unaffected area, for a “softer” look. They both last the same amount of time.
