In a patient with chronic insomnia already under bromazepam 3 mg treatment, the addition of lemborexant 5 mg prolonged the sleep duration from 6.3 hours to 7.2 hours. The combination therapy of lemborexant and bromazepam might prolong sleep duration than using romazepam alone in a metabolic dysfunction-associated steatohepatitis (MASH) patient under weekly subcutaneous tirzepatide (Mounjaro) treatment. Moreover, this literature highlights a potential association between the addition of lemborexant and the occurrence of dreams in a patient receiving chronic bromazepam therapy.
