Diabetes drug metformin could be repurposed to help slow aging mechanisms

Metformin, a widely prescribed, safe and inexpensive drug for type 2 diabetes, is a first-line treatment that lowers blood sugar and improves the body's response to insulin.

This activates a key cellular energy sensor called AMPK, which helps trigger cellular waste cleanup and supports cellular repair. Now, a recent review suggests metformin might also help counter some effects of aging.
