How Lorazepam Works: The Mechanism of Action
Lorazepam works as a central anxious system (CNS) depressant. Its primary mechanism includes the improvement of gamma-aminobutyric acid (GABA), the most prevalent inhibitory 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 specific benzodiazepine receptors on the GABA-A receptor complex. This binding increases the frequency at which the chloride channel opens, enabling more chloride ions to get in the nerve cell. The resulting hyperpolarization makes the nerve cell less most likely to fire, successfully decreasing the CNS. This process induces a soothing effect, unwinds muscles, and reduces the probability of seizures.
