CELLCEPT (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: MMF is a white to off-white crystalline powder. It is slightly soluble in water (43 µg/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. MMF hydrochloride has a solubility of 65.8 mg/mL in 5% Dextrose Injection USP (D5W). The pH of the reconstituted solution is 2.4 to 4.1. CELLCEPT is available for oral administration as capsules containing 250 mg of MMF, tablets containing 500 mg of MMF, and as a powder for oral suspension which, when reconstituted, contains 200 mg/mL of MMF. Inactive ingredients in CELLCEPT 250 mg capsules include croscarmellose sodium, magnesium stearate, povidone (K-90) and pregelatinized starch. The capsule shells contain black iron oxide, FD&C blue #2, gelatin, red iron oxide, silicon dioxide, sodium lauryl sulfate, titanium dioxide, and yellow iron oxide. Inactive ingredients in CELLCEPT 500 mg tablets include croscarmellose sodium, magnesium stearate, microcrystalline cellulose, povidone (K-90), and Opadry ® lavender Y-5R-10272-A (hydroxypropyl methylcellulose, hydroxypropyl cellulose, titanium dioxide, polyethylene glycol 400, FD&C Blue No. 2 aluminum lake [indigo carmine aluminum lake], and red iron oxide). Inactive ingredients in CELLCEPT Oral Suspension include aspartame, citric acid anhydrous, colloidal silicon dioxide, methylparaben, mixed fruit flavor, sodium citrate dihydrate, sorbitol, soybean lecithin, and xanthan gum. CELLCEPT Intravenous is the hydrochloride salt of MMF. The chemical name for the hydrochloride salt of MMF is 2-morpholinoethyl (E)-6-(1,3-dihydro-4-hydroxy-6-methoxy-7-methyl-3-oxo-5-isobenzofuranyl)-4-methyl-4-hexenoate hydrochloride. It has an empirical formula of C 23 H 31 NO 7 HCl and a molecular weight of 469.96. CELLCEPT Intravenous is available as a sterile white to off-white lyophilized powder in single-dose vials containing MMF hydrochloride for administration by intravenous infusion only. Each vial contains 500 mg of mycophenolate mofetil equivalent to 542 mg of mycophenolate mofetil hydrochloride. The inactive ingredients are polysorbate 80, 25 mg, and citric acid, 5 mg. Sodium hydroxide or hydrochloric acid may have been used in the manufacture of CELLCEPT Intravenous to adjust the pH. Reconstitution and dilution with 5% Dextrose Injection USP yields a slightly yellow solution of MMF, 6 mg/mL [see Dosage and Administration (2.6) ]. Chemical Structure
