                Narcolepsy

                History of hypersensitivity to daridorexant or its excipients

                Cautions

                Worsening depression or suicidal ideation may occur; caution in patients exhibiting symptoms of depression; monitor signs and symptoms of suicide, and provide protective measures

                Sleep paralysis (an inability to move or speak for up to several minutes during sleep-wake transitions) and hypnagogic/hypnopompic hallucinations (including vivid and disturbing perceptions) can occur; explain the nature of these events when prescribing

                Cognitive and behavioral changes (eg, amnesia, anxiety, hallucinations, other neuropsychiatric symptoms) reported with hypnotics; “sleep driving” and other complex behaviors (eg, preparing and eating food, making phone calls, having sex), with amnesia for the event, have been reported; discontinue therapy immediately if complex sleep behavior experienced

                Consider effects on respiratory function if prescribed to patients with compromised respiratory function; not studied in patients with moderate obstructive sleep apnea (OSA) requiring continuous positive airway pressure, severe OSA, or severe chronic obstructive pulmonary disease

                Reevaluate patients for comorbid conditions if insomnia persists after 7-10 days of treatment

                CNS depressant effects

                • May impair daytime wakefulness, even when used as prescribed
                • CNS-depressant effects may persist up to several days after discontinuing
                • Advise patients of potential for next-day somnolence
                • Increased risk of daytime impairment may occur if dose taken with less than a full night of sleep or with higher than recommended dose
                • Coadministration with other CNS depressants (eg, benzodiazepines, opioids, tricyclic antidepressants, alcohol) increases risk of CNS depression, which can cause daytime impairment
                • Dosage adjustments of daridorexant and concomitant CNS depressants may be necessary when administered together because of potentially additive effects
                • Not recommended for concomitant use with other drugs for insomnia
                • Alcohol consumption during therapy not recommended
                • Patients, especially elderly individuals, may be at higher risk of falls owing to potential for drowsiness
                • Symptoms similar to mild cataplexy reported with orexin receptor antagonists; suchsymptoms can include periods of leg weakness lasting from seconds to few minutes, can occureither at night or during day, and may not be associated with an identified triggering event (eg, laughter or surprise)

                Drug interaction overview

                • Substrate of CYP3A4
                • Strong or moderate CYP3A4 inhibitors
                  • Strong CYP3A4 inhibitors: Avoid coadministration
                  • Moderate CYP3A4 inhibitors: Not to exceed 25 mg/night
                  • Strong or moderate CYP3A4 inhibitors may increase exposure and risk of daridorexant adverse reactions
                • Strong or moderate CYP3A4 inducers
                  • Not recommended
                  • Strong or moderate CYP3A4 inducers may decrease exposure and efficacy of daridorexant
                • Alcohol and other CNS depressants
                  • Avoid alcohol consumption
                  • Use with caution; consider dosage adjustment of both daridorexant and/or CNS depressants
                  • Alcohol and other CNS depressants may lead to additive impairment of psychomotor skills and risk of CNS depression

                Pregnancy & Lactation

                Pregnancy

                No data are available on use in pregnant females to evaluate for drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes

                Pregnancy exposure registry

                • Monitors pregnancy outcomes in females exposed to drug during pregnancy
                • Encourage patients to call Idorsia Pharmaceutical Ltd. at 1-833-400-9611

                Animal data

                • In pregnant rats, orally administered doses up to 300 mg/kg/day during organogenesis did not cause maternal or embryofetal toxicities or fetal malformations
                • In pregnant rabbits, orally administered doses up to 120 mg/kg/day during organogenesis did not cause fetal toxicities or malformations; maternal toxicities (eg, decreased weight gain, decreased food consumption) reported

                Lactation

                There are no data on presence of drug in human milk, effects on breastfed infants, or effects on milk production

                Drug and metabolite are present in rat milk; when drug is present in animal milk, it is likely that the drug will be present in human milk

                Pregnancy Categories

                A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

                B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

                C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

                D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

                X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

                NA: Information not available.

                Pharmacology

                Mechanism of Action

                Dual orexin antagonist (DORA)

                Orexins are neuropeptides that regulate the sleep-wake cycle; orexins promote wakefulness by binding G-protein-coupled receptors, OX1R and OX2R

                Blocking neuropeptides from binding to OX1R and OX2R is believed to suppress wake drive

                Absorption

                Peak plasma time: 1-2 hr

                Bioavailability: 62%

                Effects of food

                • Healthy adults: High-fat and high-calorie meal delay peak plasma time by 1.3 hr and decreased peak plasma concentration by 16%; no effect on AUC

                Distribution

                Vd: 31 L

                Protein bound: 99.7%

                Metabolism

                Extensively metabolized by CYP3A4 (89%)

                Other CYP enzymes contribute to <3% of daridorexant metabolic clearance

                Elimination

                Half-life: 8 hr

                Excretion (primarily as metabolites, traces of parent drug): 57% (feces); 28% (urine)
