No specific drugs have been approved for the treatment of sarcopenia. Testosterone treatment may increase muscle mass and strength in older men with low serum testosterone levels (<200–300 ng/mL) and muscle weakness.[1] In addition, preliminary evidence suggests that myostatin inhibitors, which block the actions of myostatin — a protein secreted by muscle cells that inhibits protein synthesis and hypertrophy — may increase muscle mass and some measures of physical performance.[2][3] However, the medical use of myostatin inhibitors as a treatment of sarcopenia is currently limited to clinical trials.
