Interactions between your drugs

Moderate

indinavir belinostat

Applies to: indinavir and belinostat

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with inhibitors of UGT1A1 may increase the plasma concentrations of belinostat, which is primarily (80% to 90%) metabolized by UGT1A1-mediated glucuronidation. Atazanavir, a UGT1A1 inhibitor, decreased the peak plasma concentration (Cmax) of belinostat by 33% but increased systemic exposure (AUC) by 1.4-fold.

MANAGEMENT: Concomitant use of belinostat with UGT1A1 inhibitors should generally be avoided. If concomitant use of a UGT1A1 inhibitor is unavoidable, the manufacturer recommends that the dosage of belinostat be decreased by 25%; 1,000 mg/m2 dose modified to 750 mg/m2, 750 mg/m2 dose modified to 562.5 mg/m2, and 500 mg/m2 dose discontinued for the duration of UGT1A1 inhibitor use and restarted at the previous dose after five half-lives of the UGT1A1 inhibitor. Patients should be monitored closely for potentially increased adverse effects of belinostat such as nausea, vomiting, diarrhea, thrombocytopenia, leukopenia (neutropenia and lymphopenia), anemia, infection, and hepatotoxicity.

Drug and food interactions

Moderate

indinavir food

Applies to: indinavir

Large amounts of food decreases the levels of indinavir in your body. Indinavir should be taken on an empty stomach, at least 1 hour before or 2 hours after a meal. This will make it easier for your body to absorb the medication. Take indinavir with a full glass (8 ounces) of water or skim milk. You may also drink juice, coffee, or tea with this medication. Drink at least 6 glasses of water each day to prevent kidney stones while you are taking indinavir. If you prefer to take the medication with food, eat only a light meal, such as dry toast with jelly, or corn flakes with skim milk and sugar. Avoid eating a high-fat meal.

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.
