The central nerve system uses numerous neurotransmitters to send signals between nerve cells. One of the most important inhibitory neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it lowers the excitability of nerve cells, essentially functioning as a "brake" for the nerve system. Lorazepam works by improving the results of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, resulting in a calming effect on the brain. This decrease in neuronal activity leads to:
