Interactions between your drugs

Moderate

mycophenolic acid isavuconazonium

Applies to: mycophenolic acid and isavuconazonium

MONITOR: Coadministration with isavuconazonium sulfate (prodrug of isavuconazole) may increase the bioavailability of mycophenolic acid. The proposed mechanism is isavuconazole inhibition of the UGT-mediated metabolism of mycophenolic acid. When a single 1 gram dose of mycophenolate mofetil was administered to healthy volunteers following multiple dosing of isavuconazonium sulfate, mycophenolic acid systemic exposure (AUC) increased by nearly 40%.

MANAGEMENT: Caution is advised when mycophenolic acid is prescribed with isavuconazonium sulfate. Clinical and laboratory monitoring are recommended following the addition or withdrawal of isavuconazonium sulfate, and the mycophenolic acid dosage adjusted as necessary.

Drug and food interactions

Moderate

mycophenolic acid food

Applies to: mycophenolic acid

ADJUST DOSING INTERVAL: Administration of enteric coated mycophenolic acid with meals may alter its pharmacokinetics relative to administration in the fasting state. When mycophenolic acid 720 mg was administered with a high-fat meal, there was a 33% decrease in the peak plasma concentration (Cmax); a 3.5-hour increase in delay time for the rise of plasma mycophenolic acid; and a 5-hour delay in the time to reach peak plasma concentration (Tmax). However, no effect was observed on the systemic exposure of mycophenolic acid.

MANAGEMENT: To avoid variability in drug absorption between doses, enteric coated formulations of mycophenolic acid should be taken on an empty stomach, one hour before or two hours after food intake. The tablets should be swallowed whole and not crushed, chewed or divided in order to maintain the integrity of the enteric coating.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
