The central worried system utilizes different neurotransmitters to send signals between nerve cells. Among the most important repressive neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it lowers the excitability of neurons, basically functioning as a "brake" for the nerve system. Lorazepam 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 effect on the brain. This reduction in neuronal activity results in:

| Insomnia (due to stress and anxiety) | 2 mg to 4 mg | When at bedtime |
| Panic Attacks | 0.5 mg to 2 mg | As needed (PRN) |
| Pre-operative Sedation | 2 mg to 4 mg | Once before procedure |
