Role of Serendipity in Drug Discovery

Serendipity, in various shades of semantic legitimacy, is abundantly evident in history of drug discovery. In the present era, although new concept of rational drug design has been introduced even then, lots of drugs have arisen, and continue to arise, from chance observation and correct scientific methods. Chance does not produce drugs; but where chances have played a pivotal role in drug discovery, the event may be considered as serendipitous.
