UNITED STATES - OCTOBER 19: Fifty milligram tablets of Pfizer antidepressant drug Zoloft are arranged at Skenderian Apothecary in Cambridge, Massachusetts on Thursday, October 19, 2006. Pfizer Inc., Novartis AG and Eli Lilly & Co. posted profit gains as the drug industry rebounded from three years of declines. Pfizer said third-quarter net income more than doubled as higher sales of pain medication Lyrica and the Celebrex arthritis treatment helped make up for revenue lost because of generic competition to the antidepressant Zoloft and the antibiotic Zithromax.
