Mechanism of Action: How It Works
To comprehend how Lorazepam relieves stress and anxiety, one must take a look at the neurochemistry of the human brain. The central anxious system utilizes different neurotransmitters to send signals between nerve cells. One of the most important repressive neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it reduces the excitability of nerve cells, essentially serving 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, resulting in a relaxing result on the brain. This reduction in neuronal activity results in:
- Muscle relaxation
- Sedation
- Lowered emotional arousal
- Anticonvulsant results
