Nitrazepam

Noctin is indicated in disturbances of sleep of various aetiology, insomnia of the neurotics, involutional restlessness, disturbances of sleep of cerebrosclerotic patients, Myoclonic seizures etc.

Nitrazepam is a benzodiazepine derivative nearly related to diazepam. Contrary to barbiturate derivatives Nitrazepam gives free way to physiologic sleep by increasing the stimulus threshold of hypocampus and does not inhibit cortical function. After a sleep with Nitrazepam patients awaken thoroughly relaxed.

Treatment of insomnia is usually initiated with a dose of 5 mg at night although 2.5 mg is appropriate in elderly patient. The dose may be increased to 10 mg at night if insomnia is severe. Myoclonic seizures: Children: (up to 30 kg of body weight) between 0.3 and 1.0 mg/kg/day given in 3 divided doses. Treatment should be initiated with lower dose than the usual recommended dosage range in order to determine tolerance and response. Dosage should be individualized for maximal beneficial effect.

CNS depressant effect increased with alcohol, barbiturates, TCAs, phenothiazines, morphine derivatives. Effects may be antagonised by theophylline. Increased levels/effects with probenecid. Reduced levels/effects with rifampicin. May reduce effects of levodopa.
