Drug Repurposing

New Drugs from Existing Drugs

Every medicine cabinet tells a story of human ingenuity—bottles of pills that lower blood pressure, ease pain, or fight infection. But hidden within these familiar drugs lies an extraordinary secret: many could treat diseases they were never designed to cure.

Consider this: the drug you take for heartburn might one day fight cancer. The cream you apply for wrinkles could slow the progression of Alzheimer's disease. The diabetes medication gathering dust in pharmacy stockrooms might hold the key to treating infertility. These aren't fantasies—they're real examples of drug repurposing, a revolutionary approach that's transforming how we discover treatments.

In an era when developing a single new drug costs billions of dollars and takes over a decade, we're sitting on a treasure trove of therapeutic possibilities. Thousands of medications already proven safe in humans are being tested for entirely new uses. It's like discovering that your reliable kitchen knife can also open paint cans, cut cardboard, and tighten screws—the tool hasn't changed, but our understanding of what it can do has expanded dramatically.
