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 prevalent repressive neurotransmitter in the human brain.
When a specific experiences high levels of stress 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, allowing more chloride ions to enter the neuron. The resulting hyperpolarization makes the nerve cell less most likely to fire, effectively decreasing the CNS. This process induces a soothing effect, unwinds muscles, and minimizes the possibility of seizures.
