When GABA binds to its receptors, it reduces the excitability of nerve cells, basically functioning as a "brake" for the nerve system. Lorazepam works by improving the impacts of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, causing a calming result on the brain. This decrease in neuronal activity leads to:
