Drug Interactions between lemborexant and Olinvyk

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of lemborexant, which is primarily metabolized by CYP450 3A4. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been reported for other CYP450 3A4 inhibitors. When coadministered with itraconazole, a potent CYP450 3A4 inhibitor, lemborexant peak plasma concentration (Cmax) and systemic exposure (AUC) increased approximately 1.4-fold and 3.8-fold, respectively. When coadministered with fluconazole, a moderate CYP450 3A4 inhibitor, lemborexant Cmax and AUC increased approximately 1.6-fold and 4.2-fold, respectively. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased exposure to lemborexant may increase the risk of adverse reactions such as central nervous system (CNS) depression, sleep paralysis, hallucinations, complex sleep behaviors, worsening of depression or suicidal ideation, nightmares, palpitations, or headache.

After administration of a high-fat, high-calorie meal (approximately 1000 calories with 500 to 600 calories from fat), lemborexant Cmax decreased by 23%, AUC increased by 18%, and the time to maximum concentration (Tmax) was delayed by 2 hours.

MANAGEMENT: The manufacturer makes no recommendation regarding administration with food; however, the time to sleep onset may be delayed if taken with or soon after a meal. Patients should avoid consumption of grapefruit, grapefruit juice, or supplements that contain grapefruit during treatment with lemborexant.

GENERALLY AVOID: Alcohol may potentiate the central nervous system (CNS) depressant effects of opioid analgesics including oliceridine. Concomitant use may result in additive CNS depression and impairment of judgment, thinking, and psychomotor skills. In more severe cases, hypotension, respiratory depression, profound sedation, coma, or even death may occur.

GENERALLY AVOID: Grapefruit or grapefruit juice may increase the plasma concentrations of oliceridine by inhibiting the CYP450 3A4-mediated metabolism of oliceridine, although the interaction has not been studied. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

MANAGEMENT: Patients should not consume alcoholic beverages or use drug products that contain alcohol during treatment with oliceridine. Any history of alcohol or illicit drug use should be considered when prescribing oliceridine, and therapy initiated at a lower dosage if necessary. Patients should be closely monitored for signs and symptoms of sedation, respiratory depression, and hypotension. Due to a high degree of interpatient variability with respect to grapefruit juice interactions, patients treated with oliceridine should preferably avoid the consumption of grapefruit and grapefruit juice.
