Drug Repurposing: A Strategic Approach to Accelerating Drug Development and Reducing R&D Costs

Drug repurposing refers to finding new indications for existing drugs. The drug development is a complex, time consuming and expensive process. Due to low success rate of new drug development drug repurposing developed. That is powerful tools are developed to support the research and development (R&D) process. The drug re-purposing process finds new therapeutic uses for current, existing, or approved drugs, different from its original use. The main aimed of Drug repurposing is to reduce research time investments and cost in Research & Development. Drug re-purposing identifies new application for already banned or existing drugs from market. It reducing time efforts, expenses and failures in drug discovery process. It is also called as drug repositioning, drug redirecting, drug reprofiling. Drug repurposing strategies have developed over the years from straight forward coincidental observations to increasingly sophisticated computational techniques in tandem with our expanding understanding of drugs, illnesses, protein targets, and signaling pathways; however, this understanding is still far from comprehensive. Repurposed medications must overcome numerous challenges before they can be successful, albeit fewer than those of novel drugs.
