Bromazepam binds to the GABA receptor GABAA, causing a conformational change and increasing the inhibitory effects of GABA. It acts as a positive modulator, increasing the receptors' response when activated by GABA itself or an agonist (such as alcohol). As opposed to barbital, BZDs are not GABA-receptor activators and rely on increasing the neurotransmitter's natural activity. Bromazepam is an intermediate-acting benzodiazepine, is moderately lipophilic compared to other substances of its class and metabolised hepatically via oxidative pathways. It does not possess any antidepressant or antipsychotic qualities.
