Mechanism of Action: How It Works
To comprehend how Lorazepam relieves stress and anxiety, one need to look at the neurochemistry of the human brain. The central nerve system uses different neurotransmitters to send signals between neurons. One of the most crucial inhibitory neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it decreases the excitability of neurons, basically functioning as a "brake" for the nerve system. Lorazepam works by boosting the results of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, leading to a soothing result on the brain. This decrease in neuronal activity results in:
- Muscle relaxation
- Sedation
- Reduced emotional stimulation
- Anticonvulsant effects

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