Bromazepam is a short-acting benzodiazepine with intermediate onset commonly used to treat panic disorders and severe anxiety.
One of the benzodiazepines that is used in the treatment of anxiety disorders. It is a Schedule IV drug in the U.S. and Canada and under the Convention on Psychotropic Substances. It is a intermediate-acting benzodiazepine.
Indicated for the short-term treatment of insomnia, short-term treatment of anxiety or panic attacks, if a benzodiazepine is required, and the alleviation of the symptoms of alcohol- and opiate-withdrawal.
Bromazepam is a lipophilic, long-acting benzodiazepine and with sedative, hypnotic, anxiolytic and skeletal muscle relaxant properties. It does not possess any antidepressant qualities.
Bromazepam, like other benzodiazepines, presents a risk of abuse, misuse, and dependence. According to many psychiatric experts, Bromazepam has a greater abuse potential than other benzodiazepines because of fast resorption and rapid onset of action.
Bromazepam binds to the GABA-A receptor producing a conformational change and potentiating its inhibitory effects. Other neurotransmitters are not influenced.
Bromazepam has anticonvulsant properties that may be attributed to its ability to bind to voltage-dependent sodium channels. Sustained repetitive firing seems to be limited by benzodiazepines effect of slowing recovery of sodium channels from inactivation.
Metabolism: Hepatically, via oxidative pathways (via an enzyme belonging to the Cytochrome P450 family of enzymes). One of the main metabolites is 3-hydroxybromazepam. It is pharmacologically active and the half life is similar to that of the parent compound.
Absorption: Bioavailability is 84% following oral administration. The time to peak plasma level is 1 - 4 hours. Bromazepam is generally well absorbed after oral administration.
Route of elimination: Urine (69%), as metabolites.
Half life: 10-20 hours
All medicines may cause side effects, but many people have no, or minor, side effects. Some medical conditions may interact with Bromazepam.
Tell your doctor or pharmacist if you have any medical conditions.
Common adverse effects include drowsiness during the day, numbed emotions, reduced alertness, confusion, fatigue, headache, dizziness, muscle weakness, ataxia and double vision. These phenomena are dose related and occur predominantly at the start of therapy, they usually disappear with repeated administration. The elderly are particularly sensitive to the effects of centrally-depressant drugs.
