Using Metformin to Improve Muscle Recovery in Older Adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial investigates the effects of metformin on muscle recovery in older adults who have experienced muscle disuse atrophy. It aims to determine whether short-term metformin treatment can enhance muscle regrowth and function by improving macrophage activity and reducing cellular senescence. The study is designed as a randomized, double-blind, placebo-controlled trial, focusing on older adults aged 60 and above who are in good health and able to ambulate independently. The ultimate goal is to develop effective therapeutic strategies to combat muscle weakness and promote recovery in the aging population.
