Attrition is especially high for drugs treating the central nervous system. The ones that do succeed rack up an average cost of $1.8 billion. So researchers are increasingly turning to the bottles already on the shelf. Proved safe for human consumption and often understood at a molecular level, today's familiar pills might just be tomorrow's medical discovery. Sometimes one man's side effect is another man's cure.
