To comprehend how Lorazepam alleviates anxiety, one need to look at the neurochemistry of the human brain. The main nerve system utilizes different neurotransmitters to send out signals in between neurons. Among the most essential repressive neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it lowers the excitability of nerve cells, basically functioning as a "brake" for the nervous system. Lorazepam works by boosting the effects of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, resulting in a relaxing impact on the brain. This reduction in neuronal activity leads to:
- Muscle relaxation
- Sedation

- Heightened anxiety and insomnia (rebound impact).
- Tremors and muscle cramps.
