When GABA binds to its receptors, it minimizes the excitability of neurons, essentially functioning as a "brake" for the worried system. Lorazepam works by boosting the impacts of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, resulting in a calming impact on the brain. This reduction in neuronal activity leads to:
