Interactions between your drugs

Moderate

eszopiclone abametapir topical

Applies to: eszopiclone and abametapir topical

GENERALLY AVOID: Based on in vitro inhibition data, a single topical application of abametapir lotion may increase plasma concentrations of drugs that are substrates of CYP450 3A4, CYP450 2B6, and CYP450 1A2 isoenzymes and increase their systemic concentrations. The proposed mechanism is high and prolonged systemic exposure to the metabolite abametapir carboxyl, which has been shown to be an in vitro inhibitor of CYP450 3A4, CYP450 2B6, and CYP450 1A2. The mean half-life of abametapir carboxyl in adults is estimated to be 71 hours or longer.

MANAGEMENT: Use of CYP450 3A4, CYP450 2B6, and CYP450 1A2 substrates should generally be avoided within 2 weeks after topical application of abametapir lotion. If this is not feasible, the manufacturer recommends avoiding use of abametapir lotion. If abametapir is used, monitor for increased toxicity of the CYP450 3A4, CYP450 2B6, and/or CYP450 1A2 substrate.

Drug and food interactions

Moderate

eszopiclone food

Applies to: eszopiclone

GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of zopiclone and eszopiclone. 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 eszopiclone (the S-enantiomer of zopiclone) with or immediately after a high-fat/heavy meal may delay the onset of hypnotic effects. In healthy adults, administration of a 3 mg dose of eszopiclone after a high-fat meal decreased the mean peak plasma drug concentration (Cmax) by 21% and delayed the time to reach peak plasma drug concentration (Tmax) by approximately 1 hour. Theoretically, this interaction should also affect racemic zopiclone.

MANAGEMENT: Patients receiving zopiclone or eszopiclone should be advised to avoid consumption of alcohol. For faster sleep onset, it may be advisable to not administer eszopiclone and zopiclone with or immediately after a high-fat/heavy meal.

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.
