mycophenolate mofetil · by roche palo
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. Mycophenolate mofetil is available for oral administration as capsules containing 250 mg of MMF, tablets containing 500 mg of MMF. Inactive ingredients in mycophenolate mofetil 250 mg capsules include croscarmellose sodium, magnesium stearate, povidone (K-90) microcrystalline cellulose, hydroxy propyl cellulose and talc. The capsule shells…

( 2.5 ) See full prescribing information (FPI) for: adjustments for renal impairment and neutropenia ( 2.5 ) 2.1 Important Administration Instructions Mycophenolate mofetil should not be used without the supervision of a physician with experience in immunosuppressive therapy. Mycophenolate Mofetil Capsules and Tablets Mycophenolate mofetil oral dosage forms (capsules or tablets) should not be used interchangeably with mycophenolic acid delayed-release tablets without supervision of a physician with experience in immunosuppressive therapy because the rates of absorption following the administration of mycophenolate mofetil oral dosage forms and mycophenolic acid delayed-release tablets are not equivalent. Mycophenolate mofetil tablets should not be crushed and mycophenolate mofetil capsules should not be opened or crushed. Patients should…
The following adverse reactions are discussed in greater detail in other sections of the label: Embryofetal Toxicity [see Warnings and Precautions (5.1) ] Lymphomas and Other Malignancies [see Warnings and Precautions 5.2) ] Serious Infections [see Warnings and Precautions (5.3) ] Blood Dyscrasias: Neutropenia, Pure Red Cell Aplasia [see Warnings and Precautions (5.4) ] Gastrointestinal Complications [see Warnings and Precautions (5.5) ] Acute Inflammatory Syndrome Associated with Mycophenolate Products s [see Warnings and Precautions (5.7) ] The most common adverse reactions in clinical trials (20 % or greater) include diarrhea, leukopenia, infection, vomiting, and there is evidence of a higher frequency of certain types of infections e.g., opportunistic infection.

An estimated total of 1557 adult patients received mycophenolate mofetil during pivotal clinical trials in the prevention of acute organ rejection. Of these, 991 were included in…
Important safety information
WARNING: EMBRYOFETAL TOXICITY, MALIGNANCIES and SERIOUS INFECTIONS Use during pregnancy is associated with increased risks of first trimester pregnancy loss and congenital malformations. Avoid if safer treatment options are available. Females of reproductive potential must be counseled regarding pregnancy prevention and planning [see Warnings and Precautions (5.1) , Use in Special Populations (8.1 , 8.3) ] . Increased risk of development of lymphoma and other malignancies, particularly of the skin [see Warnings and Precautions (5.2) ] . Increased susceptibility to bacterial, viral, fungal and protozoal infections, including opportunistic infections and viral reactivation of hepatitis B and C, which may lead to hospitalizations and fatal outcomes [see Warnings and Precautions (5.3) ] .

See FPI for drugs that may interfere with systemic exposure and reduce mycophenolate mofetil efficacy: antacids with magnesium or aluminum hydroxide, proton pump inhibitors, drugs that interfere with enterohepatic recirculation, telmisartan, calcium-free phosphate binders. ( 7.1 ) Mycophenolate mofetil may reduce effectiveness of oral contraceptives. Use of additional barrier contraceptive methods is recommended. ( 7.2 ) See FPI for other important drug interactions. ( 7 ) 7.1 Effect of Other Drugs on Mycophenolate Mofetil Table 7 Drug Interactions with Mycophenolate mofetil that Affect Mycophenolic Acid (MPA) Exposure Antacids with Magnesium or Aluminum Hydroxide Clinical Impact Concomitant use with an antacid containing magnesium or aluminum hydroxide decreases MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may reduce mycophenolate mofetil efficacy. Prevention or Management Administer magnesium or aluminum hydroxide containing antacids at least 2h after mycophenolate mofetil administration. Proton Pump Inhibitors (PPIs) Clinical Impact Concomitant use with PPIs decreases MPA systemic exposure [see Clinical Pharmacology (12.3) ] , which may reduce mycophenolate mofetil efficacy. Prevention or Management Monitor patients for alterations in efficacy when PPIs are co-administered with mycophenolate mofetil. Examples Lansoprazole, pantoprazole Drugs that…
