Are all new drugs 'healthy'?

Abstract

"The race for the launch of new drugs, brands and combination drugs has resulted in nearly 50-80 new entries in the market in the year 2002 alone. Is it 'healthy' to have such a flooding of the market with new drugs? Do these new drugs really have benefits over their older congeners as most of them claim to have? To answer these questions, we need to look at two important aspects in the field of new drug marketing: safety and claims of superiority."(pg 11)
