Sirolimus acts as an mTOR inhibitor that prevents the activation of T-cells and B-cells in response to cytokine stimulation. By blocking this cell cycle progression, it effectively prevents the immunological mechanisms that cause organ rejection.
Pregnancy and breastfeeding
Pregnancy: Must not be used in pregnancy. Breastfeeding: Must not be used while breastfeeding.
