When GABA binds to its receptors, it reduces the excitability of neurons, essentially functioning as a "brake" for the worried system. click here works by improving the results of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, leading to a relaxing impact on the brain. This decrease in neuronal activity leads to:

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