Dey L.P. to Market EMSAM(R) Skin Patch for Treatment of Major Depressive DisorderPITTSBURGH, May 29 /PRNewswire-FirstCall/ -- Dey L.P., a subsidiary of Mylan Inc. (Nasdaq: MYL), today announced that it has begun to market and distribute EMSAM® in the U.S. EMSAM, a selegiline transdermal system, is a monoamine oxidase inhibitor (MAOI), which was approved by the U.S. Food and Drug Administration (FDA) in 2006 for the treatment of major depressive disorder.

Dey President Carolyn Myers, Ph.D., said, "I am very pleased that we have the opportunity to bring the marketing and distribution of EMSAM back into the Mylan family of companies. EMSAM was developed by Somerset in collaboration with Mylan and is manufactured by MTI. Now, we can market and distribute this important product through our specialty division, Dey, and the entire supply and distribution process will benefit from additional efficiencies and cost synergies going forward."
