First reality does not always match the theory. Second cell biology data must be interpreted within the context of a specific environment. Third the specificity of an enzyme inhibitor is always relative. Finally a critical evaluation of the benefit risk ratio of a drug must be carefully conducted and checked before and after launch. Well designed post-marketing surveillance is mandatory. The process leading to the discovery of a new drug has completely changed during the past few years. Most therapeutic molecules launched before the 1990s were discovered by unsophisticated screening tests or by chance without any hypothesis as to their mechanism of action. Studies on mechanism were usually performed after the drug had appeared on the market sometimes many years after its commercialization. The late 20th century saw the beginning of unparalleled advances in the field of molecular biology that have turned drug discovery upside down. Drug development is now based on basic research findings such as the effects of over-expression or deletion of genes encoding novel proteins or
