When GABA binds to its receptors, it minimizes the excitability of nerve cells, essentially serving as a "brake" for the nervous system. Lorazepam works by enhancing the results of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, resulting in a relaxing result on the brain. This reduction in neuronal activity results in:
