DORMICUM 7.5MG TAB NETMidazolam 7. 5mg tablets exert their effects primarily through interaction with the gamma aminobutyric acid (GABA) receptors in the brain. It belongs to the class of drugs known as benzodiazepines, which enhance the activity of GABA, an inhibitory neurotransmitter. When administered, midazolam binds to specific benzodiazepine receptors, increasing the frequency of chloride channel opening, which leads to an influx of chloride ions into the neurons.
