While benzodiazepines are a broad class of medication, as central nervous system depressants, they all work in basically the same way, creating intense feelings of sedation and relaxation as well as induce sleep by creating an excess of a neurotransmitter called gamma-Aminobutyric acid (GABA).GABA is responsible for slowing down activity in the central nervous system to regulate feelings of anxiety and stress, keeping the nerve signals that carry those feelings from reaching the brain.Benzodiazepines mimic the GABA produced by your body to bind with what are known as GABA receptors.Binding with the receptors activates them, which the benzos do over and over until the brain and nervous system are flooded with an excess of GABA.
