Pharmaceutical Research & Development (R&D) refers to the process of discovering, designing, and developing new drugs and therapies for the prevention, treatment, or management of diseases. It is a complex and multi-stage process that involves scientific exploration, preclinical testing, clinical trials, and regulatory approval.During pharmaceutical R&D, researchers and scientists work to identify potential drug targets, understand disease mechanisms, and discover or design chemical compounds or biological agents that can interact with those targets.
