The pharmaceutical industry's best new drugs may already exist.
Sildenafil was a cardiovascular compound before it became a treatment for erectile dysfunction and pulmonary arterial hypertension. Thalidomide was a sedative before it became foundational in multiple myeloma treatment. Nitisinone was developed as a herbicide before it received FDA approval in 2025 as the first targeted therapy for alkaptonuria.
Drug repurposing — finding new therapeutic applications for existing compounds — is not a niche strategy. It is one of the most scientifically rigorous and commercially intelligent approaches to drug development available. The molecule's safety profile is known. The manufacturing process exists. The pharmacokinetic behavior in humans is established.
What remains to be done — proving efficacy in the new indication, establishing the appropriate dose, characterizing safety in the new patient population, navigating the regulatory pathway — is substantial. But it starts from a place of greater biological knowledge than any new molecular entity can offer.
We've written a detailed breakdown of drug repurposing as a clinical development strategy — what AI is doing to accelerate candidate identification, what the clinical development program for a repurposed drug actually requires, and why India is an increasingly strategic location for repurposing proof-of-concept studies.
