When GABA binds to its receptors, it minimizes the excitability of neurons, basically functioning as a "brake" for the nerve system. Lorazepam works by enhancing the results of GABA. By binding to GABA-A receptors, Lorazepam increases the frequency with which the chloride channel opens, leading to a soothing effect on the brain. This decrease in neuronal activity leads to:

| Anxiety attack | 0.5 mg to 2 mg | As needed (PRN) |
| Pre-operative Sedation | 2 mg to 4 mg | When before procedure |
