It is rapidly converted into 1,25-dihydroxyvitamin D3 in the liver, which regulates calcium and phosphate metabolism, increases intestinal absorption of calcium and phosphate, promotes bone mineralization, lowers plasma parathyroid hormone levels, and reduces bone calcium dissolution.

Mycophenolate mofetil (MMF) is a 2-ethyl ester derivative of mycophenolic acid (MPA). MPA is a highly effective, selective, non-competitive, and reversible inhibitor of inosine mononucleotide dehydrogenase (IMPDH) and can inhibit the classical synthesis pathway of guanine nucleotides. MPA has a highly selective effect on lymphocytes. Mycophenolate mofetil tablets are extremely effective in preventing rejection reactions after renal transplantation and treating refractory rejection.

This product is an acetanilide antipyretic analgesic. It inhibits cyclooxygenase and selectively inhibits the synthesis of prostaglandins in the hypothalamic temperature regulation center, leading to peripheral vasodilation and sweating to achieve an antipyretic effect. Its antipyretic effect is similar to that of aspirin. It inhibits the synthesis and release of prostaglandins, etc., increases the pain threshold and has an analgesic effect. It is a peripheral analgesic, weaker than aspirin, and is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect.

This product can inhibit the synthesis of prostaglandins and has antipyretic and analgesic effects
