Lemborexant is primarily used in the treatment of insomnia, specifically for adults who have difficulty falling asleep or staying asleep. It works by targeting orexin receptors in the brain, which helps regulate the sleep-wake cycle. By blocking these receptors, it promotes sleep onset and maintenance, offering a more natural sleep pattern compared to some traditional sleep aids. It is typically taken orally in tablet form, shortly before bedtime, and is designed for short-term or long-term use depending on the patient’s condition and physician’s guidance. Lemborexant is often preferred for its lower risk of dependency and fewer residual effects upon waking, making it a suitable option for individuals seeking effective insomnia management.
