Used primarily for the treatment of insomnia, particularly in patients who have difficulty falling asleep. It works by targeting the sleep-wake cycle through selective agonism of melatonin receptors in the brain. Unlike traditional sleep medications that act on GABA receptors, this compound offers a different mechanism, reducing the risk of dependence and abuse. It is especially beneficial for long-term use in chronic insomnia and is effective in older adults due to its favorable safety profile. Also used in circadian rhythm sleep disorders, helping realign the body's internal clock. Not a controlled substance, making it a preferred option in patients with a history of substance abuse.
