Interactions between your drugs

Moderate

amobarbital idelalisib

Applies to: amobarbital and idelalisib

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of idelalisib, which is a substrate of the isoenzyme. In healthy volunteers, administration of a single 150 mg dose of idelalisib with the potent CYP450 3A4 inducer rifampin (600 mg daily for 8 days) decreased mean idelalisib peak plasma concentration (Cmax) by 58% and systemic exposure (AUC) by 75%. Data are not available for idelalisib in combination with other, less potent CYP450 3A4 inducers.

MANAGEMENT: Patients receiving idelalisib with CYP450 3A4 inducers should be monitored for potentially diminished pharmacologic response to idelalisib. Concomitant use should be avoided if an interaction is suspected.

Drug and food interactions

Major

amobarbital food

Applies to: amobarbital

GENERALLY AVOID: Concurrent acute use of barbiturates and ethanol may result in additive CNS effects, including impaired coordination, sedation, and death. Tolerance of these agents may occur with chronic use. The mechanism is related to inhibition of microsomal enzymes acutely and induction of hepatic microsomal enzymes chronically.

MANAGEMENT: The combination of ethanol and barbiturates should be avoided.

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.
