Common Name

Flurazepam

Class

Small Molecule

Description

Flurazepam is only found in individuals that have used or taken this drug. It is a benzodiazepine derivative used mainly as a hypnotic. [PubChem]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.

Toxicity Profile

Route of Exposure

Oral. Flurazepam hydrochloride is rapidly (30 minutes) absorbed from the gastrointestinal tract

Mechanism of Toxicity

Benzodiazepines bind nonspecifically to bezodiazepine receptors BNZ1, which mediates sleep, and BNZ2, which affects affects muscle relaxation, anticonvulsant activity, motor coordination, and memory. As benzodiazepine receptors are thought to be coupled to gamma-aminobutyric acid-A (GABAA) receptors, this enhances the effects of GABA by increasing GABA affinity for the GABA receptor. Binding of GABA to the site opens the chloride channel, resulting in a hyperpolarized cell membrane that prevents further excitation of the cell.

Metabolism

Flurazepam is rapidly metabolized and is excreted primarily in the urine. Both hydroxyethyl flurazepam (the major metabolite) and N-desalkyl flurazepam are active. The N-desalkyl metabolite is slowly excreted in the urine as the conjugated form Route of Elimination: Flurazepam is rapidly metabolized and is excreted primarily in the urine. Less than 1% of the dose is excreted in the urine as N1-desalkyl-flurazepam. Half Life: The mean apparent half-life of flurazepam is 2.3 hours. The half life of elimination of N1-des-alkyl- flurazepam ranged from 47 to 100 hours

Toxicity Values

Not Available

Lethal Dose

Not Available

Carcinogenicity (IARC Classification)

No indication of carcinogenicity to humans (not listed by IARC).

Uses/Sources

For short-term and intermittent use in patients with recurring insomnia and poor sleeping habits

Minimum Risk Level

Not Available

Health Effects

They cause slurred speech, disorientation and "drunken" behavior. They are physically and psychologically addictive.

Symptoms

Coma, confusion, low blood pressure, sleepiness

Treatment

General supportive measures should be employed, along with immediate gastric lavage. Intravenous fluids should be administered and an adequate airway maintained. Hypotension and CNS depression may be combated by judicious use of appropriate therapeutic agents. If excitation occurs in patients following Flurazepam overdosage, barbiturates should not be used. Flumazenil, a specific benzodiazepine-receptor antagonist, is indicated for the complete or partial reversal of the sedative effects of benzodiazepines and may be useful in situations when an overdose with a benzodiazepine is known or suspected.

Target Details

20. Translocator protein

General Function:: Cholesterol binding
Specific Function:: Can bind protoporphyrin IX and may play a role in the transport of porphyrins and heme (By similarity). Promotes the transport of cholesterol across mitochondrial membranes and may play a role in lipid metabolism (PubMed:24814875), but its precise physiological role is controversial. It is apparently not required for steroid hormone biosynthesis. Was initially identified as peripheral-type benzodiazepine receptor; can also bind isoquinoline carboxamides (PubMed:1847678).
Gene Name:: TSPO
Uniprot ID:: P30536
Molecular Weight:: 18827.81 Da
