When GABA binds to its receptors, it minimizes the excitability of nerve cells, essentially acting as a "brake" for the nerve system. Lorazepam works by boosting the results of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, leading to a soothing impact on the brain. This decrease in neuronal activity leads to:
