What Is Drug Repurposing in Cancer Treatment and How Does It Work?

Drug repurposing involves finding new anticancer uses for existing, clinically approved drugs originally developed for other medical conditions, such as metformin, statins, and vitamin D. These drugs have known safety profiles and pharmacokinetic properties.

Drug repurposing is cost-effective and faster than developing new drugs from scratch, thanks to existing safety data. It also has a reduced risk of failure in clinical trials due to the established safety profiles of the drugs.
