How Lorazepam Works: The Mechanism of Action
Lorazepam operates as a main nerve system (CNS) depressant. Its primary mechanism involves the enhancement of gamma-aminobutyric acid (GABA), the most prevalent inhibitory neurotransmitter in the human brain.
When an individual experiences high levels of tension or anxiety, neuronal activity in the brain ends up being overstimulated. Lorazepam binds to particular benzodiazepine receptors on the GABA-A receptor complex. This binding increases the frequency at which the chloride channel opens, permitting more chloride ions to get in the nerve cell. The resulting hyperpolarization makes the nerve cell less likely to fire, effectively decreasing the CNS. This process induces a soothing impact, relaxes muscles, and reduces the possibility of seizures.
