Pharmacology
- Indication
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.
- Associated Conditions
- Pharmacodynamics
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.
- Mechanism of action
Bromazepam binds to the GABA-A receptor producing a conformational change and potentiating its inhibitory effects. Other neurotransmitters are not influenced.
- 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.
- Volume of distribution
1.56 L/kg
- Protein binding
70%
- 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.
- Route of elimination
Urine (69%), as metabolites
- Half life
10-20 hours
- Clearance
0.82 mL/min/kg.
