Sirolimus

Sirolimus is a medication primarily used to prevent organ rejection in transplant patients and treat certain rare diseases. It works by inhibiting a protein that helps control cell growth and immune responses, thereby suppressing the body's tendency to reject a transplanted organ. Also known as rapamycin, it can have side effects, including increased risk of infections and some metabolic changes. Sirolimus is taken as a pill or liquid, and its use is closely monitored by healthcare professionals to ensure effectiveness while minimizing risks.
