Zoloft goes off-patent, Greenstone to launch Authorized Generic

Ivax has launched its generic Zoloft as Sertraline hydrochloride, active ingredient of Zoloft, went off-patent on June 30, 2006. After Zocor (Simvastatin) and Proscar (Finasteride), Zoloft is another blockbuster drug which losses patent protection this year with Ivax to enjoy 180-day marketing exclusivity. However, in another development Pfizer’s subsidiary Greenstone Ltd. is all set to launch Authorized Generic of Zoloft to compete Ivax’s generic version during 180-days marketing exclusivity period. After Merck authorizing Dr. Reddy’s to launch authorized generics of Zocor and Proscar, Pfizer's move doesn’t come as a surprise to generic players. Amidst of these developments, its time for Indian Generic players to go Dr. Reddy’s way, that is, be an Authorized Generic. Don’t you think its better way to take away U.S. generic share?
