MPA exhibits a cytostatic effect on T and B lymphocytes. It is an inhibitor of inosine monophosphate dehydrogenase (IMPDH) which inhibits de novo guanosine nucleotide synthesis. T and B lymphocytes are dependent on this pathway for proliferation.
Rapid and extensive; early post-transplant period mycophenolic acid (MPA) AUC values are lower (~45% to 53%) than later post-transplant period (>3 months) MPA AUC values in both pediatric patients and adults
Oral: Myfortic: 93%
CellCept: MPA: Oral: 4 L/kg; IV: 3.6 L/kg
Myfortic: MPA: Oral: 54 L (at steady state); 112 L (elimination phase)
Hepatic and via GI tract; CellCept is completely hydrolyzed in the liver to mycophenolic acid (MPA; active metabolite); enterohepatic recirculation of MPA may occur; MPA is glucuronidated to MPAG (inactive metabolite)
CellCept: MPA: Urine (<1%), feces (6%); MPAG: Urine (87%)
Myfortic: MPA: Urine (3%), feces; MPAG: Urine (>60%)
Onset of Action
Peak effect: Correlation of toxicity or efficacy is still being developed, however, one study indicated that 12-hour AUCs >40 mcg/mL/hour were correlated with efficacy and decreased episodes of rejection
Time to Peak
Plasma: Oral: MPA:
CellCept: 1 to 1.5 hours
Myfortic: 1.5 to 2.75 hours
CellCept: MPA: Oral: 18 hours; IV: 17 hours
Myfortic: MPA: Oral: 8 to16 hours; MPAG: 13 to 17 hours
MPA: >97%, MPAG 82%
Special Populations: Renal Function Impairment
Mycophenolic acid AUC increased 75%, and mycophenolic acid glucuronide AUC increased 3- to 6-fold in patients with severe renal impairment (glomerular filtration rate [GFR] <25 mL/minute/1.73 m2). Hemodialysis usually does not remove mycophenolic acid or mycophenolic acid glucuronide.
Use: Labeled Indications

Psoriasis, moderate-to-severe (off-label use): CellCept: Oral: 2-3 g daily (Menter, 2009)
Dosage is the same as younger patients, however, dosing should be cautious due to possibility of increased hepatic, renal, or cardiac dysfunction. Elderly patients may be at an increased risk of certain infections, gastrointestinal hemorrhage, and pulmonary edema, as compared to younger patients.
Renal transplant: Oral:
CellCept: Infants ≥3 months, Children, and Adolescents: Cellcept suspension: 600 mg/m2/dose twice daily; maximum dose: 1 g twice daily
Alternatively, may use Cellcept solid dosage forms according to BSA as follows:
BSA 1.25 to 1.5 m2: 750 mg capsule twice daily
BSA >1.5 m2: 1 g capsule or tablet twice daily
Myfortic: Children ≥5 years and Adolescents: Usual dosage: 400 mg/m2/dose twice daily; maximum dose: 720 mg twice daily
BSA <1.19 m2: Use of this formulation is not recommended
BSA 1.19 to 1.58 m2: 540 mg twice daily (maximum: 1080 mg daily)
BSA >1.58 m2: 720 mg twice daily (maximum: 1440 mg daily)
Dosing: Renal Impairment
Renal transplant: GFR <25 mL/minute/1.73 m2 in patients outside the immediate post-transplant period:
CellCept: Doses of >1 g administered twice daily should be avoided; patients should also be carefully observed; no dose adjustments are needed in renal transplant patients experiencing delayed graft function postoperatively
Myfortic: No dose adjustments are needed in renal transplant patients experiencing delayed graft function postoperatively; however, monitor carefully for potential concentration dependent adverse events
Cardiac or liver transplant: No data available; mycophenolate may be used in cardiac or hepatic transplant patients with severe chronic renal impairment if the potential benefit outweighs the potential risk.
Autoimmune disease (off-label use): There have been no specific dosage adjustments identified, although use of lower doses may be required. MPA exposure appears to be inversely related to renal function (Abd Rahman, 2013); monitor closely for efficacy and adverse effects, especially in patients with end-stage renal disease (Haubitz, 2002; MacPhee, 2000).
Hemodialysis: Not removed; supplemental dose is not necessary.
Peritoneal dialysis: Supplemental dose is not necessary.
Dosing: Hepatic Impairment
No dosage adjustment is recommended for renal patients with severe hepatic parenchymal disease; however, it is not currently known whether dosage adjustments are necessary for hepatic disease with other etiologies.
Dosing: Adjustment for Toxicity
Neutropenia (ANC <1.3 x 103/μL): Dosing should be interrupted or the dose reduced, appropriate diagnostic tests performed and patients managed appropriately
Oral suspension: Should be constituted prior to dispensing to the patient and not mixed with any other medication. Add 47 mL of water to the bottle and shake well for ~1 minute. Add another 47 mL of water to the bottle and shake well for an additional minute. Final concentration is 200 mg/mL of mycophenolate mofetil.
IV: Reconstitute the contents of each vial with 14 mL of 5% dextrose injection; dilute the contents of a vial with 5% dextrose in water to a final concentration of 6 mg mycophenolate mofetil per mL. Note: Vial is vacuum-sealed; if a lack of vacuum is noted during preparation, the vial should not be used.
A 50 mg/mL oral suspension may be made with mycophenolate mofetil capsules, Ora-Plus, and cherry syrup. In a vertical flow hood, empty six 250 mg capsules into a mortar; add 7.5 mL Ora-Plus and mix to a uniform paste. Mix while adding 15 mL of cherry syrup in incremental proportions; transfer to a calibrated bottle, rinse mortar with cherry syrup, and add sufficient quantity of cherry syrup to make 30 mL. Label "shake well". Stable for 210 days at 5°C, for 28 days at 25°C to 37°C, and for 11 days at 45°C.Venkataramanan R, McCombs JR, Zuckerman S, et al, "Stability of Mycophenolate Mofetil as an Extemporaneous Suspension," Ann Pharmacother, 1998, 32(7-8):755-7.9681090
Oral dosage formulations (tablet, capsule, suspension) should be administered on an empty stomach (1 hour before or 2 hours after meals) to avoid variability in MPA absorption. The oral solution may be administered via a nasogastric tube (minimum 8 French, 1.7 mm interior diameter); oral suspension should not be mixed with other medications. Delayed release tablets should not be crushed, cut, or chewed. Cellcept may be administered with food in stable renal transplant patients when necessary. If a dose is missed, administer as soon as it is remembered. If it is close to the next scheduled dose, skip the missed dose and resume at next regularly scheduled time; do not double a dose to make up for a missed dose.
Intravenous solutions should be administered over at least 2 hours (either peripheral or central vein); do not administer intravenous solution by rapid or bolus injection.
Some products may contain phenylalanine.

Data for incidence >20% as reported in adults following oral dosing of CellCept alone in renal, cardiac, and hepatic allograft rejection studies. Profile in 3% to <20% range reflects use in combination with cyclosporine and corticosteroids. In general, lower doses used in renal rejection patients had less adverse effects than higher doses. Rates of adverse effects were similar for each indication, except for those unique to the specific organ involved. The type of adverse effects observed in pediatric patients was similar to those seen in adults, with the exception of abdominal pain, anemia, diarrhea, fever, hypertension, infection, pharyngitis, respiratory tract infection, sepsis, and vomiting, which were more frequent in pediatric patients; lymphoproliferative disorder was the only type of malignancy observed. Percentages of adverse reactions were similar in studies comparing CellCept to Myfortic in patients following renal transplant.

Concerns related to adverse effects:
• Infections: [US Boxed Warning]: Risk for bacterial, viral, fungal, and protozoal infections, including opportunistic infections, is increased with immunosuppressant therapy; infections may be serious and potentially fatal. Due to the risk of oversuppression of the immune system, which may increase susceptibility to infection, combination immunosuppressant therapy should be used with caution.
• New or reactivated viral infections: Polyomavirus associated nephropathy (PVAN), JC virus-associated progressive multifocal leukoencephalopathy (PML), cytomegalovirus (CMV) infections, and reactivation of hepatitis B (HBV) or hepatitis C (HCV) have been reported with use. A reduction in immunosuppression should be considered for patients with new or reactivated viral infections; however, in transplant recipients, the risk that reduced immunosuppression presents to the functioning graft should also be considered. PVAN, primarily from activation of BK virus, may lead to the deterioration of renal function and/or renal graft loss. PML, a potentially fatal condition, commonly presents with apathy, ataxia, cognitive deficiencies, confusion, and hemiparesis. Risk factors for development of PML include treatment with immunosuppressants and immune function impairment; consultation with a neurologist should be considered in any patient with neurological symptoms receiving immunosuppressants. Risk of CMV viremia or disease is increased in transplant recipients CMV seronegative at the time of transplant who receive a graft from a CMV seropositive donor; however, routine approaches to limiting CMV exist and should be utilized. In patients infected with HBV or HCV, viral reactivation may occur; these patients should be monitored for signs of active HBV or HCV.
• Lymphoproliferative disorders: [US Boxed Warning]: Risk of development of lymphoma and skin malignancy is increased. The risk for malignancies is related to intensity/duration of therapy. Patients should be monitored appropriately, instructed to limit exposure to sunlight/UV light to decrease the risk of skin cancer, and given supportive treatment should these conditions occur. Post-transplant lymphoproliferative disorder related to EBV infection has been reported in immunosuppressed organ transplant patients; risk is highest in EBV seronegative patients (including many young children).
• Neutropenia: Neutropenia (including severe neutropenia) may occur, requiring dose reduction or interruption of treatment (risk greater from day 31-180 post-transplant).
• Pure red cell aplasia (PRCA): PRCA, a type of anemia which can range from subclinical to severe, has been reported in patients receiving mycophenolate concomitantly with other immunosuppressive agents (eg, tacrolimus, cyclosporine, corticosteroids). Symptoms may include fatigue, lethargy, or pallor. Although not precisely known, risk factors for the development of PRCA may include immunosuppression and treatment with immunosuppressant therapy. Dose reduction or discontinuation of immunosuppressive therapy may reverse PRCA; however, in transplant recipients, the risk of reduced immunosuppression and graft rejection should be considered.
• Gastrointestinal disorders: Use may rarely be associated with gastric or duodenal ulcers, GI bleeding and/or perforation. Use caution in patients with active serious digestive system disease; patients with active peptic ulcers were not included in clinical studies.
• Hypoxanthine-guanine phosphoribosyltransferase deficiency: Theoretically, use should be avoided in patients with the rare hereditary deficiency of hypoxanthine-guanine phosphoribosyltransferase (such as Lesch-Nyhan or Kelley-Seegmiller syndrome).
• Renal impairment: Use with caution in patients with renal impairment as toxicity may be increased; may require dosage adjustment in severe impairment.
Dosage form specific issues:
• Non-interchangeability of dosage forms: Mycophenolate sodium and mycophenolate mofetil should not be used interchangeably without health care provider supervision because the rate of absorption following the administration of these two products is not equivalent. Single dose pharmacokinetic studies in adult renal transplant patients suggest that bioavailability is similar between oral mycophenolate mofetil (1,000 mg) and delayed release mycophenolic acid (720 mg) (Arns, 2005). In clinical trials, comparative efficacy and safety profiles have been observed in adult renal transplant patients randomized to either oral mycophenolate mofetil (1,000 mg twice daily) or delayed release mycophenolic acid (720 mg twice daily) (Budde, 2004; Salvadori, 2003).
• Phenylalanine: Some dosage forms may contain phenylalanine.
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson, 2002; Lucente 2000; Shelley, 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade, 1986; CDC, 1984). See manufacturer’s labeling.
• Pregnancy: [US Boxed Warning]: Mycophenolate is associated with an increased risk of congenital malformations and first trimester pregnancy loss when used by pregnant women. Females of reproductive potential must be counseled about pregnancy prevention and planning. Alternative agents should be considered for women planning a pregnancy. Females of reproductive potential should have a negative pregnancy test with a sensitivity of ≥25 milliunits/mL immediately before therapy and the test should be repeated 8-10 days later. Pregnancy tests should be repeated during routine follow-up visits. Acceptable forms of contraception should be used during treatment and for 6 weeks after therapy is discontinued.
• Because mycophenolate mofetil has demonstrated teratogenic effects in rats and rabbits, tablets should not be crushed or cut, and capsules should not be opened or crushed. Avoid inhalation or direct contact with skin or mucous membranes of the powder contained in the capsules and the powder for oral suspension. Caution should be exercised in the handling and preparation of solutions of intravenous mycophenolate. Avoid skin contact with the intravenous solution and reconstituted suspension. If such contact occurs, wash thoroughly with soap and water, rinse eyes with plain water.
• Experienced physician: [US Boxed Warning]: Should be administered under the supervision of a physician experienced in immunosuppressive therapy.
• Immunizations: Live attenuated vaccines should be avoided during use; vaccinations may be less effective during therapy.
• IV administration: Intravenous solutions should be given over at least 2 hours; never administer intravenous solution by rapid or bolus injection.
Complete blood count (weekly for first month, twice monthly during months 2 and 3, then monthly thereafter through the first year); renal and liver function; signs and symptoms of organ rejection; signs and symptoms of bacterial, fungal, protozoal, new or reactivated viral, or opportunistic infections; neurological symptoms (eg, hemiparesis, confusion, cognitive deficiencies, ataxia) suggestive of PML, pregnancy test (immediately prior to initiation and 8-10 days later in females of childbearing potential, followed by repeat tests during therapy); monitor skin (for lesions suspicious of skin cancer); monitor for signs of lymphoma
Pregnancy Risk Factor
[US Boxed Warning]: Mycophenolate is associated with an increased risk of congenital malformations and first trimester pregnancy loss when used by pregnant women. Females of reproductive potential must be counseled about pregnancy prevention and planning. Alternative agents should be considered for women planning a pregnancy. The following congenital malformations have been reported following exposure during pregnancy: external ear abnormalities, cleft lip and palate, anomalies of the distal limbs, heart, esophagus, kidney, and nervous system. Spontaneous abortions have also been noted. Females of reproductive potential (girls who have entered puberty, women with a uterus who have not passed through clinically confirmed menopause) should have a negative pregnancy test with a sensitivity of ≥25 milliunits/mL immediately before therapy and the test should be repeated 8 to 10 days later. Pregnancy tests should be repeated during routine follow-up visits. Acceptable forms of contraception should be used during treatment and for 6 weeks after therapy is discontinued. The effectiveness of hormonal contraceptive agents may be affected by mycophenolate. Mycophenolate is not recommended for the treatment of psoriasis in pregnant women (Menter 2009). For women with lupus nephritis taking mycophenolate and who are planning a pregnancy, mycophenolate should be discontinued at least 6 weeks prior to trying to conceive (Hahn 2012).
Health care providers should report female exposures to mycophenolate during pregnancy or within 6 weeks of discontinuing therapy to the Mycophenolate Pregnancy Registry (800-617-8191).
The National Transplantation Pregnancy Registry (NTPR) is a registry which follows pregnancies which occur in maternal transplant recipients or those fathered by male transplant recipients. The NTPR encourages reporting of pregnancies following solid organ transplant by contacting them at 877-955-6877 or NTPR@giftoflifeinstitute.org.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before?
