Potential for the development of lymphoma and other malignancies, particularly of the skin, which may result from immunosuppression. Because of the increased risk for skin cancer, patients should be advised to limit their exposure to sunlight or other UV light by wearing protective clothing and using sunscreen with a high protection factor. Lymphoproliferative disease or lymphoma occurred in 0.4-1% of allograft recipients receiving mycophenolate mofetil in conjunction with other immunosuppressive agents in clinical studies. Non-melanoma skin carcinoma was reported in 1.6-4.2% of patients while other types of malignancy were reported in 0.7-2.1% of patients.

Mycophenolate mofetil is a prodrug of mycophenolic acid (MPA). The active form of mycophenolate, MPA, prevents the proliferation of immune cells and the formation of antibodies that cause transplant rejection. The above effects lead to higher rates of successful transplantation, avoiding the devastating effects of graft rejection.

Absorption
Mycophenolate mofetil is rapidly absorbed in the small intestine. The maximum concentration of its active metabolite, MPA, is attained 60 to 90 minutes following an oral dose. The average bioavailability of orally administered mycophenolate mofetil in a pharmacokinetic study of 12 healthy patients was 94%. In healthy volunteers, the Cmax of mycophenolate mofetil was 24.5 (9.5)g/mL. In renal transplant patients 5 days post-transplant, Cmax was 12.0 (3.82) g/mL, increasing to 24.1 (12.1)g/mL 3 months after transplantation. AUC values were 63.9 (16.2) gh/mL in healthy volunteers after one dose, and 40.8 (11.4) gh/mL, and 65.3 (35.4)gh/mL 5 days and 3 months after a renal transplant, respectively. The absorption of mycophenolate mofetil is not affected by food.
Route of Elimination
A small amount of drug is excreted as MPA in the urine (less than 1%). When mycophenolate mofetil was given orally in a pharmacokinetic study, it was found to be 93% excreted in urine and 6% excreted in feces. Approximately 87% of the entire administered dose is found to be excreted in the urine as MPAG, an inactive metabolite.
Volume of Distribution
The volume of distribution of mycophenolate mofetil is 3.6 (1.5) to 4.0 (1.2) L/kg.
Clearance
Plasma clearance of mycophenolate mofetil is 193 mL/min after an oral dose and 177 (31) mL/min after an intravenous dose.
/Absorption/ is rapid and extensive after oral administration.
Thomson/Micromedex. Drug Information for the Health Care Professional. Volume 1, Greenwood Village, CO. 2006., p. 2142
In 12 healthy volunteers, the mean absolute bioavailability of oral mycophenolate mofetil relative to intravenous mycophenolate mofetil (based on MPA AUC) was 94%. The area under the plasma-concentration time curve (AUC) for MPA appears to increase in a dose-proportional fashion in renal transplant patients receiving multiple doses of mycophenolate mofetil up to a daily dose of 3 g.

Protein binding: To plasma albumin: High (97% for mycophenolic acid (MPA) at concentration ranges normally seen in stable renal transplant patients). At higher mycophenolic acid glucuronide (MPAG) concentrations (e.g., in patients with renal impairment or delayed graft function), binding of MPA may be decreased as a result of competition between MPA and MPAG for binding sites.
Thomson/Micromedex. Drug Information for the Health Care Professional. Volume 1, Greenwood Village, CO. 2006., p. 2142
The mean (+/-SD) apparent volume of distribution of MPA in 12 healthy volunteers is approximately 3.6 (+/-1.5) and 4.0 (+/-1.2) L/kg following intravenous and oral administration, respectively. MPA, at clinically relevant concentrations, is 97% bound to plasma albumin. MPAG is 82% bound to plasma albumin at MPAG concentration ranges that are normally seen in stable renal transplant patients; however, at higher MPAG concentrations (observed in patients with renal impairment or delayed renal graft function), the binding of MPA may be reduced as a result of competition between MPAG and MPA for protein binding. Mean blood to plasma ratio of radioactivity concentrations was approximately 0.6 indicating that MPA and MPAG do not extensively distribute into the cellular fractions of blood.

After both oral and intravenous administration mycophenolate mofetil is entirely metabolized by liver carboxylesterases 1 and 2 to mycophenolic acid (MPA), the active parent drug. It is then metabolized by the enzyme glucuronyl transferase, producing the inactive phenolic glucuronide of MPA (MPAG). The glucuronide metabolite is important, as it is then converted to MPA through enterohepatic recirculation. Mycophenolate mofetil that escapes metabolism in the intestine enters the liver via the portal vein and is transformed to pharmacologically active MPA in the liver cells.N-(2-carboxymethyl)-morpholine, N-(2-hydroxyethyl)-morpholine, and the N-oxide portion of N-(2-hydroxyethyl)-morpholine are additional metabolites of MMF occurring in the intestine as a result of liver carboxylesterase 2 activity. UGT1A9 and UGT2B7 in the liver are the major enzymes contributing to the metabolism of MPA in addition to other UGT enzymes, which also play a role in MPA metabolism. The four major metabolites of MPA are 7-O-MPA--glucuronide (MPAG, inactive), MPA acyl-glucuronide (AcMPAG), produced by uridine 5-diphosphate glucuronosyltransferases (UGT) activities, 7-O-MPA glucoside produced via UGT, and small amounts 6-O-des-methyl-MPA (DM-MPA) via CYP3A4/5 and CYP2C8 enzymes.
Following oral and intravenous dosing, mycophenolate mofetil undergoes complete metabolism to MPA /mycophenolic acid/, the active metabolite. Metabolism to MPA occurs presystemically after oral dosing. MPA is metabolized principally by glucuronyl transferase to form the phenolic glucuronide of MPA (MPAG) which is not pharmacologically active. In vivo, MPAG is converted to MPA via enterohepatic recirculation. The following metabolites of the 2- hydroxyethyl-morpholino moiety are also recovered in the urine following oral administration of mycophenolate mofetil to healthy subjects: N-(2-carboxymethyl)-morpholine, N-(2- hydroxyethyl)-morpholine, and the N-oxide of N-(2-hydroxyethyl)-morpholine.

The average apparent half-life of mycophenolate mofetil is 17.9 (6.5) hours after oral administration and 16.6 (5.8) hours after intravenous administration.
For mycophenolic acid (MPA):Mean apparent: Approximately 17.9 hours after oral administration and 16.6 hours after intravenous administration.
Thomson/Micromedex. Drug Information for the Health Care Professional. Volume 1, Greenwood Village, CO. 2006., p. 2142
Mean (+/-SD) apparent half-life and plasma clearance of MPA are 17.9 (+/-6.5) hours and 193 (+/-48) mL/min following oral administration and 16.6 (+/-5.8) hours and 177 (+/-31) mL/min following intravenous administration, respectively.

The active metabolite of mycophenolate, mycophenolic acid, prevents T-cell and B-cell proliferation and the production of cytotoxic T-cells and antibodies. Lymphocyte and monocyte adhesion to endothelial cells of blood vessels that normally part of inflammation is prevented via the glycosylation of cell adhesion molecules by MPA. MPA inhibits de novo purine biosynthesis (that promotes immune cell proliferation) by inhibiting inosine 5-monophosphate dehydrogenase enzyme (IMPDH), with a preferential inhibition of IMPDH II. IMPDH normally transforms inosine monophosphate (IMP) to xanthine monophosphate (XMP), a metabolite contributing to the production of guanosine triphosphate (GTP). GTP is an important molecule for the synthesis of ribonucleic acid (RNA), deoxyribonucleic acid (DNA), and protein. As a result of the above cascade of effects, mycophenolate mofetil reduces de-novo production of guanosine nucleotides, interfering with the synthesis of DNA, RNA, and protein required for immune cell production. Further contributing to the above anti-inflammatory effects, MMF depletes tetrahydrobiopterin, causing the decreased function of inducible nitric oxide synthase enzyme, in turn decreasing the production of peroxynitrite, a molecule that promotes inflammation.
As a potent, selective, noncompetitive, and reversible, inhibitor of inosine monophosphate dehydrogenase (IMPDH), mycophenolic acid (MPA), the active metabolite /of mycophenolate mofetil/, inhibits the de novo synthesis pathway of guanosine nucleotides without being incorporated into DNA. Because T and B lymphocytes are critically dependent for their proliferation on de novo synthesis of purines, while other cell types can utilize salvage pathways, MPA has potent cytostatic effects on lymphocytes. MPA inhibit proliferative responses of T and B lymphocytes to both mitogenic and allospecific stimulation. The addition of guanosine or deoxyguanosine reverses the cytostatic effects of MPA on lymphocytes. MPA also suppresses antibody formation by B lymphocytes. MPA prevents the glycosylation of lymphocytes and monocyte glycoproteins that are involved in intercellular adhesion of these cells to endothelial cells, and may inhibit recruitment of leukocytes into sites of inflammation and graft rejection. Mycophenolate mofetil dose not inhibit the early events in the activation of human peripheral blood mononuclear cells, such as the production of interleukin-1 and interleukin-2, but does block the coupling of these events to DNA synthesis and proliferation.
