Please scroll down our right margin and click on Dan Carlat's blog regarding the drug industry. Here's a teaser:
Yesterday, the FDA gave official approval to Wyeth's antidepressant Prisiq. Here are the top 5 reasons for doctors to keep it off their prescription pads.
1. It’s a blatant patent extender. Effexor XR, which brought in $3.8 billion for Wyeth in 2007, is losing patent protection this year, and Wyeth is introducing desvenlafaxine, which is simply Effexor’s main metabolite, as a “novel antidepressant.” There’s nothing novel about it. Every patient who takes Effexor produces Pristiq in their own body, at no additional charge.
2. It’s not very effective. In the studies released so far, Pristiq just barely squeaks by placebo on the Hamilton Depression scale. In the U.S. study, Pristiq decreased the HamD by only 2 points (-11.5 vs. -9.5 for placebo), and in the European study, the differences was 2.5 points. And for the higher 100 mg dose, there was no difference between drug and placebo for U.S. patients.
