How Lorazepam Works: The Mechanism of Action
Lorazepam works as a main nervous system (CNS) depressant. Its main system involves the enhancement of gamma-aminobutyric acid (GABA), the most common repressive neurotransmitter in the human brain.
When an individual experiences high levels of stress or 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, allowing more chloride ions to go into the nerve cell. The resulting hyperpolarization makes the nerve cell less likely to fire, successfully slowing down the CNS. This process causes a relaxing result, relaxes muscles, and lowers the likelihood of seizures.
