Bromazepamum [inn-latin]

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.

pharmacology

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 shares with other benzodiazepines the risk of abuse, misuse, psychological and/or physical 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 receptor GABAA, causing a conformational change and increasing inhibitory effects of GABA. Other neurotransmitters are not influenced.

biotransformation

Hepatically, via oxidative pathways (via an enzyme belonging to the Cytochrome P450 family of enzymes).

absorption

Bioavailability is 84% following oral administration.

half life

10-20 hours
