Longevity and Aging

Mechanism of Action

Inhibiting mTOR signaling pathway contributes to potential health span and longevity benefits in animal models, according to the National Institute on Aging 1
Stimulating autophagy, which becomes dysfunctional with aging, is a mechanism by which rapamycin may exert its effects, as reported by the National Institute on Aging 1

Rapamycin extends mammalian lifespans in multiple species, as recognized by the National Institute on Aging 2
Rapamycin reduces frailty index scores in mice with enhanced NF-κB signaling and accelerated aging, suggesting potential benefits for healthspan 3
Rapamycin increases longevity in female mice, but not consistently in male mice, highlighting the need for further research on sex-specific effects 3

Newer rapamycin analogs that selectively target TORC1 with fewer side effects are being investigated as potential treatments for age-related diseases, as reported by the National Institute on Aging 1
The American Thoracic Society, American College of Chest Physicians, and National Institute of Diabetes and Digestive and Kidney Diseases recommend careful patient selection and monitoring due to potential side effects, including hyperlipidemia, poor wound healing risk, and renal insufficiency 4, 5

The American Heart Association, American Thoracic Society, and American College of Cardiology recommend regular monitoring of drug concentration, lipid panels, complete blood count (CBC), creatinine, and blood pressure during treatment with rapamycin 4
The Infectious Diseases Society of America, National Kidney Foundation, and American Academy of Infectious Diseases suggest avoiding rapamycin in patients with active infections, renal insufficiency, or abnormal elevation of fasting triglycerides 4, 6, 5
The American Medical Association recommends initial evaluation, including complete health assessment, lipid panel, CBC, and comprehensive metabolic panel, to exclude contraindications and assess risk factors before off-label use of rapamycin for longevity purposes 4

The American Geriatrics Society suggests starting with a low dose (1mg weekly) and monitoring for side effects, and considering intermittent dosing to minimize side effects while maintaining benefits 4
The American College of Cardiology warns of potential side effects of rapamycin, including hyperlipidemia, increased risk of infections, and potential pulmonary toxicity (monitor for new respiratory symptoms) 4
