What is rapamycin (sirolimus)?

Rapamycin, also called sirolimus, is a macrolide drug that inhibits the mTOR pathway. It is used clinically as an immunosuppressant, especially in organ transplantation.

What is rapamycin used for medically?

Rapamycin is used to help prevent organ transplant rejection by suppressing immune activation. It may also be used in certain mTOR-related conditions depending on clinical context.

Why is rapamycin studied for longevity?

Rapamycin extends lifespan in multiple animal models, likely by reducing mTOR signaling involved in growth and nutrient sensing. Human longevity benefits are not established.

Can rapamycin help prevent or treat cancer?

Rapamycin and related drugs can slow growth in some mTOR-driven cancers and are used in specific oncology settings. Effects vary by cancer type and should be managed by specialists.

What are common safety concerns with rapamycin?

Because it suppresses immunity, rapamycin can increase infection risk and may affect wound healing. It can also interact with other medicines, so medical supervision is important.

Rapamycin (sirolimus) is an mTOR inhibitor used for immunosuppression and studied for longevity and cancer prevention effects.

Longevity Anti-Aging Cancer-inhibitor

Doz aralığı

1–6 mg

Weekly or daily depending on indication and monitoring.

Gelir

Take orally, consistently with or without food, but avoid high-fat meals that can increase absorption; monitor blood levels if prescribed.

Yağda çözünür: yağ ile birlikte alın.

En iyi zaman

Immunosuppression regimens typically use daily dosing; longevity research often involves intermittent weekly dosing, which is not FDA-approved.

Açıklama

Rapamycin, also known as sirolimus, is a macrolide compound developed as an immunosuppressive drug for organ transplantation and is now widely researched for its effects on aging and cancer through inhibition of the mTOR pathway.
