How Lorazepam Works: The Mechanism of Action

Lorazepam works as a main nerve system (CNS) depressant. Its primary system includes the improvement of gamma-aminobutyric acid (GABA), the most widespread repressive neurotransmitter in the human brain.

When an individual experiences high levels of tension or stress and anxiety, neuronal activity in the brain becomes overstimulated. Lorazepam binds to particular benzodiazepine receptors on the GABA-A receptor complex. This binding increases the frequency at which the chloride channel opens, enabling more chloride ions to enter the nerve cell. The resulting hyperpolarization makes the nerve cell less likely to fire, efficiently decreasing the CNS. This process induces a soothing effect, relaxes muscles, and decreases the likelihood of seizures.
