4 Drug and Medication Information
4.1 Drug 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.


5 Pharmacology and Biochemistry
5.1 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, 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.


5.2 MeSH Pharmacological Classification

GABA Modulators

Substances that do not act as agonists or antagonists but do affect the GAMMA-AMINOBUTYRIC ACID receptor-ionophore complex. GABA-A receptors (RECEPTORS, GABA-A) appear to have at least three allosteric sites at which modulators act: a site at which BENZODIAZEPINES act by increasing the opening frequency of GAMMA-AMINOBUTYRIC ACID-activated chloride channels; a site at which BARBITURATES act to prolong the duration of channel opening; and a site at which some steroids may act. GENERAL ANESTHETICS probably act at least partly by potentiating GABAergic responses, but they are not included here. (See all compounds classified as GABA Modulators.)


Anti-Anxiety Agents

Agents that alleviate ANXIETY, tension, and ANXIETY DISORDERS, promote sedation, and have a calming effect without affecting clarity of consciousness or neurologic conditions. ADRENERGIC BETA-ANTAGONISTS are commonly used in the symptomatic treatment of anxiety but are not included here. (See all compounds classified as Anti-Anxiety Agents.)

5.4 Absorption, Distribution and Excretion

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


Volume of Distribution

1.56 L/kg


Clearance

0.82 mL/min/kg.


5.5 Metabolism/Metabolites

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.


Bromazepam has known human metabolites that include 3-Hydroxybromazepam.

5.6 Biological Half-Life

10-20 hours


5.7 Mechanism of Action

Bromazepam binds to the GABA-A receptor producing a conformational change and potentiating its inhibitory effects. Other neurotransmitters are not influenced.
