Mechanism of Action: How It Works
To comprehend how Lorazepam minimizes anxiety, one need to look at the neurochemistry of the human brain. The main anxious system uses numerous neurotransmitters to send signals in between neurons. One of the most crucial inhibitory neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it lowers the excitability of neurons, essentially functioning 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, resulting in a relaxing result on the brain. This reduction in neuronal activity results in:
- Muscle relaxation

| Panic Attacks | 0.5 mg to 2 mg | As needed (PRN) |
| Pre-operative Sedation | 2 mg to 4 mg | When before procedure |
