The central nerve system utilizes different neurotransmitters to send signals in between neurons. Among the most essential inhibitory neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it reduces the excitability of nerve cells, basically serving as a "brake" for the nervous system. Lorazepam works by enhancing the effects of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, causing a relaxing impact on the brain. This decrease in neuronal activity leads to:
