Interactions between your drugs

Moderate

zolpidem cobicistat

Applies to: Ambien CR (zolpidem) and cobicistat

MONITOR: Coadministration with cobicistat may increase the plasma concentrations of drugs that are substrates of the CYP450 3A4 or 2D6 isoenzymes and/or P-glycoprotein (P-gp) efflux transporter.

MANAGEMENT: Caution is advised if cobicistat is used concomitantly with medications that undergo metabolism primarily by CYP450 3A4 and/or 2D6 or are substrates of P-glycoprotein, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever cobicistat is added to or withdrawn from therapy.

Drug and food interactions

Moderate

zolpidem food

Applies to: Ambien CR (zolpidem)

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

ADJUST DOSING INTERVAL: Administration of zolpidem with food may delay the onset of hypnotic effects. In 30 healthy subjects, administration of zolpidem 20 minutes after a meal resulted in decreased mean peak plasma drug concentration (Cmax) and area under the concentration-time curve (AUC) by 25% and 15%, respectively, compared to fasting. The time to reach peak plasma drug concentration (Tmax) was prolonged by 60%, from 1.4 to 2.2 hours.

MANAGEMENT: Patients receiving zolpidem should be advised to avoid the consumption of alcohol. For faster sleep onset, zolpidem should not be administered with or immediately after a 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.
