Mechanism of Action

Mycophenolic acid acts by blocking purine synthesis of human lymphocytes through reversible inhibition of inosine monophosphate dehydrogenase. It also inhibits proliferation of both T- and B- lymphocytes. Absorption: Mycophenolate mofetil/mycophenolate sodium: Both extensively absorbed from the GI tract. Distribution: Mycophenolic acid (MPA): 97% bound to plasma proteins. Metabolism: Mycophenolate is converted to active MPA, which undergoes enterohepatic recirculation. MPA is metabolised by glucuronidation to the inactive glucuronide. Excretion: Via urine (as the glucuronide and negligible amounts of MPA); via faeces (about 6% of a dose). Mean half-life of MPA: 17.9 hr (as oral mycophenolate mofetil) and 16.6 hr (as IV mycophenolate mofetil); 12 hr (as mycophenolate sodium).
