Lexa-H Tablet is a combination medication containing Melatonin 3 mg and Zolpidem 5 mg, formulated to aid in the management of insomnia characterized by difficulty in falling asleep and maintaining sleep continuity. Melatonin, a naturally occurring hormone produced by the pineal gland, regulates the circadian rhythm and promotes the initiation of sleep. Zolpidem, a non-benzodiazepine hypnotic agent, acts selectively on the GABA-A receptor complex to exert sedative and hypnotic effects, facilitating sleep induction. The synergistic action of Melatonin and Zolpidem in Lexa-H Tablet enhances sleep quality while minimizing the latency period. This medication is indicated for short-term treatment of insomnia when sleep disturbances significantly impair daytime functioning. Lexa-H Tablet should be taken orally, preferably 30 minutes before bedtime, with caution advised in patients with hepatic or renal impairment, respiratory conditions, or a history of substance abuse. Common adverse effects may include dizziness, headache, and gastrointestinal discomfort. Due to the potential for dependence and tolerance with prolonged use of Zolpidem, therapy duration should be limited as per physician guidance. Lexa-H Tablet is contraindicated in patients with hypersensitivity to its components and should be used under strict medical supervision to optimize therapeutic outcomes and minimize risks.
