How Lorazepam Works: The Mechanism of Action
Lorazepam operates as a central nerve system (CNS) depressant. Its primary mechanism involves the improvement of gamma-aminobutyric acid (GABA), the most widespread repressive neurotransmitter in the human brain.
When a specific 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, permitting more chloride ions to go into the neuron. The resulting hyperpolarization makes the nerve cell less most likely to fire, successfully decreasing the CNS.
