fluvoxaMINE quizartinib

Applies to: fluvoxamine and quizartinib

Coadministration with mild or moderate inhibitors of CYP450 3A4 is not expected to have clinically significant effects on the pharmacokinetics of quizartinib or its major circulating active metabolite, AC886. According to the prescribing information, quizartinib is primarily metabolized via oxidation by CYP450 3A4/5 in vitro, and AC886 is formed and metabolized by CYP450 3A4/5. Following coadministration of a single 53 mg dose of quizartinib with ketoconazole, a potent CYP450 3A4 inhibitor, quizartinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 17% and 94%, respectively, while the Cmax and AUC of AC886 decreased by 60% and 94%, respectively. By contrast, clinically significant changes in the Cmax and AUC of quizartinib and AC886 were not observed following coadministration of single-dose quizartinib with fluconazole, a moderate CYP450 3A4 inhibitor. Therefore, no dosage adjustments are recommended when quizartinib is coadministered with mild and moderate CYP450 3A4 inhibitors.

Drug and food interactions

fluvoxaMINE food

Applies to: fluvoxamine

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.

MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol. Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

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.
