Mechanism of Action: How It Works
To comprehend how Lorazepam minimizes anxiety, one must look at the neurochemistry of the human brain. The central nerve system utilizes different neurotransmitters to send out signals between neurons. Among the most essential repressive neurotransmitters is Gamma-aminobutyric acid (GABA).
When GABA binds to its receptors, it minimizes the excitability of nerve cells, basically serving as a "brake" for the nerve system. Lorazepam works by enhancing the impacts 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 reduction in neuronal activity results in:

| Pre-operative Sedation | 2 mg to 4 mg | Once before procedure |

The Risk of Dependency and Withdrawal
