How Lorazepam Works: The Mechanism of Action
Lorazepam functions as a main nerve system (CNS) depressant. Its main mechanism includes the improvement of gamma-aminobutyric acid (GABA), the most widespread 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 go into the nerve cell. The resulting hyperpolarization makes the neuron less most likely to fire, successfully slowing down the CNS. This procedure induces a relaxing result, unwinds muscles, and lowers the likelihood of seizures.
