MYFORTIC S360 MG

About

Mycophenolate sodium is an enteric-coated formulation of mycophenolic acid, a potent and selective immunosuppressant. Its primary mechanism of action involves the reversible and non-competitive inhibition of inosine monophosphate dehydrogenase (IMPDH), a key enzyme in the de novo pathway of guanosine nucleotide synthesis. This pathway is particularly critical for the proliferation of T and B lymphocytes, which are central to the adaptive immune response, as these cells rely heavily on the de novo pathway for nucleotide synthesis, unlike other cell types that can utilize salvage pathways. By selectively depleting guanosine nucleotides in lymphocytes, mycophenolate sodium effectively inhibits their proliferation and function, thereby suppressing the immune system. It is primarily used in combination with other immunosuppressive agents, such as ciclosporin and corticosteroids, for the prophylaxis of acute organ rejection in patients receiving allogeneic renal, cardiac, or hepatic transplants, significantly improving graft survival rates and reducing rejection episodes.
