Abstract

A favourable risk-benefit ratio is the necessary requirement of any drug treatment. It is well known that the data contributing to the evaluation of this ratio are only partially available when a new drug is released for marketing [1–5]. This establishes the need for further investigations on both efficacy and safety in everyday clinical practice (table 1).
