Lemborexant is a dual antagonist of the orexin OX1 and OX2 receptors.[5][6][7]

Pharmacokinetics

The time to peak levels of lemborexant is 1 to 3 hours.[1] A high-fat and high-calorie meal has been found to delay the time to peak levels by 2 hours.[1] Its plasma protein binding in vitro is 94%.[1] Lemborexant is metabolized primarily by CYP3A4 and to a lesser extent by CYP3A5.[1] The elimination half-life of lemborexant is 17 to 19 hours.[1] The medication is excreted in feces (57%) and to a lesser extent urine (29%).[1]

History
