Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Mycophenolate mofetil is a reversible inhibitor of inosine monophosphate dehydrogenase (IMPDH), inhibiting de novo purine synthesis in T and B lymphocytes, thereby suppressing lymphocyte proliferation.
Immunosuppressant; binds to cyclophilin D in mitochondria, inhibiting opening of mitochondrial permeability transition pore (m PTP), which reduces T-lymphocyte activation and cytokine release. Also forms complex with cyclophilin A to inhibit calcineurin, suppressing IL-2 production and T-cell proliferation.
Prophylaxis of organ rejection in renal transplant recipients,Prophylaxis of organ rejection in cardiac transplant recipients,Prophylaxis of organ rejection in hepatic transplant recipients,Off-label: Treatment of lupus nephritis, autoimmune diseases, and other transplant indications
Dry eye disease due to keratoconjunctivitis sicca (KCS),Post-keratoplasty dry eye,Dry eye in Sjögren's syndrome
Oral: 1-2 g daily in two divided doses. Intravenous: 1-2 g daily in two divided doses as a 2-hour infusion.
Instill one drop of 0.09% ophthalmic solution in each eye twice daily, approximately 12 hours apart.
Terminal elimination half-life of MPA is approximately 17.9 ± 6.5 hours in renal transplant patients. Clinical significance: dosing interval of 12 hours maintains therapeutic levels.
Terminal elimination half-life is approximately 8.4 hours (range 6-10 hours) in healthy adults; prolonged in hepatic impairment and pediatric patients.
Mycophenolate mofetil is hydrolyzed to mycophenolic acid (MPA), the active metabolite. MPA is primarily metabolized by glucuronidation via UDP-glucuronosyltransferases (UGT1A9 and UGT2B7) to MPA-glucuronide (MPAG), which is excreted in urine.
Hepatic via CYP3A4 and CYP3A5; also undergoes fecal elimination with enterohepatic recirculation.
Mycophenolic acid (MPA) is primarily excreted in urine as mycophenolic acid glucuronide (MPAG) (87% of dose); <1% excreted as unchanged MPA. Fecal excretion accounts for approximately 6% of dose.
Primarily fecal (90%) with minor renal excretion (<1% unchanged drug). Biliary excretion is the major route for elimination of cyclosporine metabolites.
97% bound to albumin. In renal impairment or hypoalbuminemia, free fraction increases.
90-98% bound primarily to lipoproteins (HDL, LDL) and to a lesser extent albumin and globulins.
Apparent volume of distribution of MPA is approximately 3.6 L/kg (range 1.5-5.0 L/kg), indicating extensive tissue distribution.
4-8 L/kg, indicating extensive distribution into tissues (e.g., fat, liver, kidneys).
Oral bioavailability of mycophenolate mofetil is approximately 94% (converted to MPA). Intravenous: 100%.
Ophthalmic emulsion: systemic bioavailability is negligible (<0.1%) due to low absorption from the eye.
For GFR 10-50 m L/min: maximum 2 g daily; for GFR <10 m L/min: maximum 1 g daily.
No dosage adjustment required for renal impairment.
No dosage adjustment required for hepatic impairment. No Child-Pugh based modifications are established.
No dosage adjustment required for hepatic impairment.
For ages 3 months to 18 years: 600 mg/m2 orally twice daily; maximum 2 g daily. Intravenous: same oral dose converted to IV.
Safety and efficacy in pediatric patients have not been established.
No specific dose adjustment, but start at lower end of dosing range due to age-related renal impairment. Monitor for adverse effects.
No specific dosage adjustment recommended; use with caution due to potential for increased systemic exposure.
Increased risk of pregnancy loss and congenital malformations; must avoid pregnancy during therapy. Use in women of childbearing potential only if contraception is used and pregnancy is excluded.
Increased risk of infection and lymphoproliferative disorders including post-transplant lymphoproliferative disorder (PTLD).
Increased susceptibility to infections (e.g., CMV, BK virus), lymphomas, and other malignancies; dose reduction in renal impairment; avoid use with azathioprine; monitor for neutropenia, GI bleeding, and progressive multifocal leukoencephalopathy.
Increased susceptibility to infections,Potential for lymphoproliferative disorders and other malignancies,May cause renal impairment, hypertension, hyperkalemia, and hyperuricemia,Monitor blood cyclosporine levels to avoid toxicity,Avoid concurrent use of live vaccines,Caution with other nephrotoxic drugs
Hypersensitivity to mycophenolate mofetil or mycophenolic acid; women who are pregnant or planning pregnancy (unless no alternative); women of childbearing potential not using effective contraception.
Hypersensitivity to cyclosporine or any component,Uncontrolled hypertension,Severe renal impairment (except in transplant setting),Active infections,Concurrent use with PUVA or UVB therapy
Avoid taking with food high in fat or protein as it may reduce absorption. Grapefruit juice may decrease mycophenolate absorption; avoid concurrent consumption. No specific dietary restrictions besides maintaining consistent intake with meals.
No significant food interactions reported for ophthalmic cyclosporine. However, patients should avoid touching the dropper tip to food surfaces. No dietary restrictions are necessary.
First trimester exposure is associated with a high risk of congenital malformations, including craniofacial defects (cleft lip/palate), cardiovascular anomalies, and neural tube defects. Second and third trimester exposure may cause intrauterine growth restriction, preterm delivery, and neonatal immunosuppression. Mycophenolic acid is contraindicated in pregnancy unless no alternative treatment is available.
CEQUA (cyclosporine ophthalmic solution) is classified as Pregnancy Category C. Animal studies have shown embryotoxic and fetotoxic effects at doses 0.2-0.8 times the human ocular dose. There are no adequate and well-controlled studies in pregnant women. Use only if potential benefit justifies potential risk to the fetus. First trimester: limited data, theoretical risk of immunosuppression. Second and third trimesters: no specific human data, but systemic cyclosporine is associated with increased risk of prematurity and low birth weight.
M/P ratio is unknown. Mycophenolic acid is excreted into breast milk in small amounts; however, due to potential for serious adverse effects in the nursing infant, including immunosuppression and growth delay, breastfeeding is not recommended during therapy.
Systemic cyclosporine is excreted in human milk. The M/P ratio is approximately 0.3-0.6. However, CEQUA is an ophthalmic formulation with minimal systemic absorption. Unknown whether topically applied cyclosporine is excreted in milk. Use caution, considering the importance of the drug to the mother. Breastfeeding infants should be monitored for potential adverse effects such as immune suppression.
No specific dose adjustments are established due to lack of pharmacokinetic data in pregnancy. Systemic exposure may be reduced due to increased plasma volume and metabolism; however, due to teratogenicity, use is contraindicated. If unavoidable, consider monitoring mycophenolic acid trough levels and adjust dose to maintain therapeutic range (1.0–3.5 mg/L), but safety is not established.
No specific dosing adjustments are recommended for CEQUA in pregnancy due to its local administration and minimal systemic absorption. Pharmacokinetic changes in pregnancy (e.g., increased volume of distribution, altered protein binding) are unlikely to affect ophthalmic drug levels. No dose adjustment required.
Mycophenolate mofetil (CELLCEPT) is a prodrug of mycophenolic acid, an inosine monophosphate dehydrogenase inhibitor. It is used for prophylaxis of organ rejection in renal, cardiac, and hepatic transplant recipients. Monitor for leukopenia, neutropenia, and infections. Dose adjustment required in renal impairment (GFR <25 m L/min). Avoid use in pregnancy (Pregnancy Category D). Contraindicated in hypersensitivity to mycophenolate. Intravenous administration should be over 2 hours. Monitor for GI bleeding and CMV infection.
CEQUA (cyclosporine ophthalmic solution 0.09%) is a calcineurin inhibitor immunosuppressant indicated for keratoconjunctivitis sicca (dry eye disease). It increases tear production by inhibiting T-cell activation. Important: CEQUA requires no refrigeration (unlike Restasis), and the vehicle contains no preservatives. Use with caution in patients with active ocular infections; do not administer while wearing contact lenses. Onset of effect may take 2-4 weeks; maximum benefit may require 6 months. Contraindicated in patients with known hypersensitivity to cyclosporine.
