By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, resulting in a relaxing effect on the brain. This reduction in neuronal activity results in:

| Sleeping disorders (due to anxiety) | 2 mg to 4 mg | As soon as at bedtime |
| Anxiety attack | 0.5 mg to 2 mg | As required (PRN) |
| Pre-operative Sedation | 2 mg to 4 mg | Once before procedure |
