Rapacan 1mg Tablet contains Sirolimus, which is an immunosuppressive drug used primarily to prevent organ rejection in transplant patients and to treat certain conditions related to the immune system.
Brand Name: Rapacan
Composition: Sirolimus 1 mg
Mechanism of Action:
By inhibiting the function of the mammalian target of rapamycin (mTOR), a crucial regulator of cell growth and metabolism, sirolimus prevents T-lymphocytes from activating and proliferating in response to antigenic and cytokine stimulation.
Uses:

Dosage and Administration:
For kidney transplants, a maintenance dose of 2 mg once daily may be administered after an initial loading dose, typically 6 mg, on the day of the transplant. Oral Rapacan tablets can be taken with or without meals. When it comes to meals, consistency is crucial.
