Drug repurposing, also known as drug repositioning or drug re-profiling, is the process of finding new uses for existing drugs that have already been approved for a specific therapeutic indication. This strategy is often pursued in order to accelerate the development of new treatments, reduce costs, and address unmet medical needs in a more efficient manner compared to traditional drug discovery and development processes. Drug repurposing involves screening existing drugs for their potential to treat different diseases or conditions based on their existing pharmacological properties, mechanisms of action, and safety profiles. The goal of drug repurposing is to leverage the knowledge and resources available for approved drugs to identify new therapeutic applications and bring them to market faster.
