Bromazepam is used to treat short-term, symptomatic anxiety. Bromazepam is not used at all in United States. Bromazepam is available in Canada under the brand names Apo-Bromazepam®, Gen-Bromazepam, Lectopam®, Novo-Bromazepam and Nu-Bromazepam.


Mechanism of Action

Binds to stereospecific benzodiazepine receptors on the postsynaptic GABA neuron at several sites within the central nervous system, including the limbic system, reticular formation. Enhancement of the inhibitory effect of GABA on neuronal excitability results by increased neuronal membrane permeability to chloride ions. This shift in chloride ions results in hyperpolarization (a less excitable state) and stabilization.

Legal status

Schedule IV(US)

Routes Oral

Overdosage Bromazepam

Symptoms of overdose include somnolence, confusion, coma, and diminished reflexes. Treatment for benzodiazepine overdose is supportive. Flumazenil has been shown to selectively block the binding of benzodiazepines to CNS receptors, resulting in a reversal of benzodiazepine-induced sedation; however, its use may not reverse respiratory depression.

Legal Status Bromazepam

Bromazepam is a Schedule IV drug under the Convention on Psychotropic Substances.
