| Mechanism of Action |
Benzodiazepines bind nonspecifically to benzodiazepine receptors, which 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 the inhibitory neurotransmitter GABA to the site opens the chloride channel, resulting in a hyperpolarized cell membrane that prevents further excitation of the cell. |
| Metabolism |
Hepatic. Temazepam is completely metabolized through conjugation prior to excretion. The major metabolite is the O-conjugate of temazepam (90%). |
| Toxicity Values |
LD50: 1963 mg/kg (oral, mice) (T343)
LD50: 1833 mg/kg (oral, rat) (T343)
LD50: >2400 mg/kg (oral, rabbit) (T343) |

| Uses/Sources |
Officially indicated for severe insomnia and other severe or disabling sleep disorders. |
| Minimum Risk Level |
Not Available |
| Health Effects |
They cause slurred speech, disorientation and "drunken" behavior. They are physically and psychologically addictive. |
| Symptoms |
Not Available |
| Treatment |
If the patient is conscious, vomiting should be induced mechanically or with emetics. Gastric lavage should be employed utilizing concurrently a cuffed endotracheal tube if the patient is unconscious to prevent aspiration and pulmonary complications. Maintenance of adequate pulmonary ventilation is essential. The use of pressor agents intravenously may be necessary to combat hypotension. Fluids should be administered intravenously to encourage diuresis. (V650) |

| Target 1 Description |
Responsible for the manifestation of peripheral-type benzodiazepine recognition sites and is most likely to comprise binding domains for benzodiazepines and isoquinoline carboxamides. May play a role in the transport of porphyrins and heme. Plays a role in the transport of cholesterol across mitochondrial membranes in steroidogenic cells (By similarity) |
