Drug information of Flurazepam
Mechanism of effect
Flurazepam, like other central nervous system agents of the 1,4-benzodiazepine class, presumably exerts its effects by binding to stereo-specific receptors at several sites within the central nervous system (CNS). The exact mechanism of action is unknown.
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 hydrochloride is rapidly absorbed from the gastro-intestinal tract. Flurazepam is rapidly metabolized and is excreted primarily in the urine. Protein binding: 83%.The mean apparent half-life of flurazepam is 2.3 hours.
Usual Adult Dose for Insomnia 30 mg orally before retiring. In some patients, 15 mg may suffice.
