Micofenolato De Mofetil Accord (Mycophenolate Mofetil)

• Mycophenolate Mofetil is used in transplant medicine and certain autoimmune diseases to suppress immune‑mediated damage.
• Kidney transplantation: prevents acute graft rejection and supports graft survival.
• Heart transplantation: reduces risk of early rejection episodes.
• Liver transplantation: helps maintain long‑term graft function.
• Lupus nephritis: diminishes renal inflammation and proteinuria.
• ANCA‑associated vasculitis: controls systemic vasculitic activity.

• Mycophenolate Mofetil selectively inhibits inosine monophosphate dehydrogenase (IMPDH), the key enzyme for de novo synthesis of guanosine nucleotides. By depleting guanosine pools, it blocks proliferation of T‑ and B‑lymphocytes, which rely on this pathway for clonal expansion, while sparing most other cell types. The effect is reversible upon drug discontinuation, allowing restoration of normal lymphocyte function.

Mycophenolate Mofetil may cause a range of adverse reactions, classified as common or serious.

Common Side Effects

• Nausea: mild to moderate upset stomach.
• Diarrhea: loose stools that may affect hydration.
• Vomiting: occasional episodes of emesis.
• Headache: transient cranial discomfort.

Serious or Rare Side Effects

• Severe infection: opportunistic bacterial, viral or fungal infections.
• Leukopenia: significant reduction in white blood cells.
• Hepatic dysfunction: elevated liver enzymes or hepatitis.

Before initiating therapy, clinicians should consider several safety measures.

• Monitor blood counts: perform regular complete blood count to detect leukopenia or anemia.
• Assess liver function: check hepatic enzymes periodically for signs of dysfunction.
• Adjust dose in renal impairment: reduce dosage in patients with reduced kidney function.
• Contraindicated in pregnancy: avoid use in pregnant women; use effective contraception.
• Avoid live vaccines: do not administer live attenuated vaccines while on therapy.
• Store at ambient temperature: keep in original container, protect from moisture and light.

Mycophenolate Mofetil can interact with several medicines, requiring caution.

Major Interactions (Avoid)

• Azathioprine: additive bone‑marrow suppression.
• Cyclosporine: increased mycophenolate exposure, risk of toxicity.
• Tacrolimus: increased exposure, may require dose adjustment.
• Live vaccines: risk of severe infection.

Moderate Interactions (Monitor Closely)

• Antacids (e.g., aluminum‑magnesium): may reduce absorption.
• Cholestyramine: can bind drug and lower plasma levels.
• Valganciclovir: additive myelosuppression risk.
