Abstract

Drug repurposing, also known as drug repositioning, is an innovative and cost-effective strategy in modern pharmacology. This research focuses on the growing trend of using already-approved drugs for new therapeutic indications. Over the past few years, advancements in bioinformatics, high-throughput screening, and molecular biology have facilitated the identification of existing drugs that may have potential efficacy in treating other diseases. The article explores the methodologies behind drug repurposing, notable case studies, the challenges faced, and the future potential of this approach in drug discovery. It also emphasizes how drug repurposing can accelerate the availability of effective treatments for unmet medical needs, reducing the burden of drug development costs and timelines.
