Mechanism of Action: How It Works
To comprehend how Lorazepam eases anxiety, one must take a look at the neurochemistry of the human brain. The central nerve system uses various neurotransmitters to send out signals in between nerve cells. One of the most essential inhibitory neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it lowers the excitability of nerve cells, basically functioning as a "brake" for the nerve system. Lorazepam works by boosting the impacts 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 decrease in neuronal activity results in:

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