When drug companies lose their patent they usually come out with another drug which is nearly the same drug. Pfizer did this, when they lost the patent on Effexor, they launched Pristiq which is actually the main metabolite of Effexor, venlafaxine hydrochloride.Another article on Prozac (from 2007):

"All good things come to an end, though, and in 2001, Prozac lost its patent. Eli Lilly lost $35m of its market value in one day - and 90 per cent of its Prozac prescriptions in a single year. Eli Lilly has now come back with Cymbalta, which it hopes will be the next Prozac. This was approved by America's Food & Drug Administration despite another very shaky start. Traci Johnson, a healthy 19-year-old college student, hung herself in the Eli Lilly laboratory while testing the drug at high doses, in return for $150 a day."

Pristiq was marketed for major depression and also as alternative to using hormone replacement therapy for the treatment of hot flashes.
