System of Action: How It Works
To understand how Lorazepam alleviates anxiety, one should look at the neurochemistry of the human brain. The central worried system uses various neurotransmitters to send out signals between nerve cells. 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 nervous 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, causing a relaxing result on the brain. This reduction in neuronal activity results in:

| General Anxiety | 1 mg to 3 mg | 2 to 3 times daily |
| Sleeping disorders (due to stress and anxiety) | 2 mg to 4 mg | Once at bedtime |
| Anxiety attack | 0.5 mg to 2 mg | As required (PRN) |
| Pre-operative Sedation | 2 mg to 4 mg | When before procedure |

- Heightened stress and anxiety and sleeping disorders (rebound impact).
- Tremblings and muscle cramps.
