Flurazepam, a benzodiazepine derivative, is a hypnotic agent which does not appear to decrease dream time as measured by rapid eye movements (REM). Furthermore, it decreases sleep latency and number of awakenings for a consequent increase in total sleep time. Flurazepam binds to an allosteric site on GABA-A receptors. Binding potentiates the action of GABA on GABA-A receptors by opening the chloride channel within the receptor, causing chloride influx and hyperpolarization.
Flurazepam is indicated in the following conditions-
Adult: Usual dosage is 30 mg at bedtime. In some patients, 15 mg may sufficient.
Elderly or debilitated: 15 mg is usually sufficient for a therapeutic response.
Children: Not recommended.
In hepatic and renal impairment: Dosage may need to be reduced in patients with impaired hepatic or renal function.
Patients with known hypersensitivity to benzodiazepines or any other ingredients of the capsule.
Dizziness, drowsiness, light-headedness, staggering, ataxia have occurred, particularly in elderly or debilitated persons. Severe sedation, lethargy, disorientation and coma have been reported.
Overdose Effects
Flurazepam overdosage includes somnolence, confusion and coma. Respiration, pulse and blood pressure should be monitored as in all cases of drug overdosage. General supportive measures should be employed, along with immediate gastric lavage.
Since the risk of the development of oversedation, dizziness, confusion or ataxia increases substantially with larger doses in elderly and debilitated patients, it is recommended that in such patients the dosage should be limited to 15 mg. The usual precautions are indicated for severely depressed patients or those in whom there is any evidence of latent depression; particularly the recognition that suicidal tendencies may be present and protective measures may be necessary. The usual precautions should be observed in patients with chronic pulmonary insufficiency.
Pregnancy & Lactation
Pregnancy category-C. Flurazepam is contraindicated in pregnant women. Lactating mothers should avoid it.
