Mycophenolate mofetil is an antimetabolite immunosuppressant. It is the 2-morpholinoethyl ester of mycophenolic acid (MPA), an immunosuppressive agent; inosine monophosphate dehydrogenase (IMPDH) inhibitor. The chemical name for mycophenolate mofetil (MMF) is 2-morpholinoethyl (E)-6-(1,3-dihydro-4-hydroxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-hexenoate. It has an empirical formula of C 23 H 31 NO 7 , a molecular weight of 433.50, and the following structural formula: Mycophenolate mofetil is a white to off-white crystalline powder. It is slightly soluble in water (43 mcg/mL at pH 7.4); the solubility increases in acidic medium (4.27 mg/mL at pH 3.6). It is freely soluble in acetone, soluble in methanol, and sparingly soluble in ethanol. The apparent partition coefficient in 1-octanol/water (pH 7.4) buffer solution is 238. The pKa values for MMF are 5.6 for the morpholino group and 8.5 for the phenolic group. Mycophenolate mofetil is available for oral administration as capsules containing 250 mg of MMF, tablets containing 500 mg of mycophenolate mofetil. Inactive ingredients in Mycophenolate mofetil capsules USP 250 mg include croscarmellose sodium, pregelatinized starch, povidone (K-90), isopropyl alcohol and magnesium stearate. The capsule shells contain gelatin, sodium lauryl sulphate, FD&C blue 2, red iron oxide, yellow iron oxide and titanium dioxide. The capsule is printed with edible black ink comprised of black iron oxide, butyl alcohol, dehydrated alcohol, isopropyl alcohol, potassium hydroxide, propylene glycol, shellac, strong ammonia solution. Inactive ingredients in mycophenolate mofetil tablets USP 500 mg include croscarmellose sodium, povidone (K-90), isopropyl alcohol, microcrystalline cellulose, magnesium stearate, hypromellose, polyethylene glycol, titanium dioxide, red iron oxide, black iron oxide, and yellow iron oxide. FDA approved dissolution test specifications differ from USP. Structure
