s that in humans at the MRHD.
Administration of suvorexant (oral doses of 30, 80, and 200 mg/kg) to pregnant rats throughout gestation and lactation resulted in decreased body weight in offspring at the highest dose tested. Plasma AUCs at the no-effect dose were approximately 25 times that in humans at the MRHD.
8.3 Nursing Mothers
Suvorexant and a hydroxyl-suvorexant metabolite were excreted in rat milk at levels higher (9 and 1.5 times, respectively) than that in maternal plasma. It is not known whether this drug is secreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when BELSOMRA is administered to a nursing woman.
8.4 Pediatric Use
Safety and effectiveness in pediatric patients have not been established
8.5 Geriatric Use
Of the total number of patients treated with BELSOMRA (n=1784) in controlled clinical safety and efficacy studies, 829 patients were 65 years and over, and 159 patients were 75 years and over. No clinically meaningful differences in safety or effectiveness were observed between these patients and younger patients at the recommended doses [see Clinical Pharmacology (12.3) and Clinical Studies (14)].
8.6 Patients with Compromised Respiratory Function
Effects of BELSOMRA on respiratory function should be considered if prescribed to patients with compromised respiratory function.
Obstructive Sleep Apnea
The respiratory depressant effect of BELSOMRA was eva luated after one night and after four consecutive nights of treatment in a randomized, placebo-controlled, 2-period crossover study in patients (n=26) with mild to moderate obstructive sleep apnea. Following once-daily doses of 40 mg, the mean Apnea/Hypopnea Index treatment difference (suvorexant – placebo) on Day 4 was 2.7 (90% CI: 0.22 to 5.09), but there was wide inter- and intra-individual variability such that clinically meaningful respiratory effects of BELSOMRA in obstructive sleep apnea cannot be excluded. BELSOMRA has not been studied in patients with severe obstructive sleep apnea [see Warnings and Precautions (5.5)].
Chronic Obstructive Pulmonary Disease
The respiratory depressant effect of BELSOMRA was eva luated after one night and after four consecutive nights of treatment in a randomized, placebo-controlled, 2-period crossover study in patients (n=25) with mild to moderate chronic obstructive pulmonary disease (COPD). BELSOMRA (40 mg in non-elderly, 30 mg in elderly) had no respiratory depressant effects in patients with mild to moderate COPD, as measured by oxygen saturation. There was wide inter- and intra-individual variability such that clinically meaningful respiratory effects of BELSOMRA in COPD cannot be excluded. BELSOMRA has not been studied in patients with severe COPD [see Warnings and Precautions (5.5)].
8.7 Patients with Hepatic Impairment
No dose adjustment is required in patients with mild and moderate hepatic impairment. BELSOMRA has not been studied in patients with severe hepatic impairment and is not recommended for these patients [see Clinical Pharmacology (12.3)].
No dose adjustment is required in patients with renal impairment [see Clinical Pharmacology (12.3)].
8.8 Patients with Renal Impairment
No dose adjustment is required in patients with renal impairment [see Clinical Pharmacology (12.3)].
