How Lorazepam Works: The Mechanism of Action
Lorazepam works as a main nerve system (CNS) depressant. Its main mechanism includes the enhancement of gamma-aminobutyric acid (GABA), the most prevalent repressive neurotransmitter in the human brain.
When an individual experiences high levels of tension or stress and anxiety, neuronal activity in the brain ends up being 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 get in the neuron. The resulting hyperpolarization makes the neuron less likely to fire, successfully slowing down the CNS. This process causes a relaxing effect, relaxes muscles, and decreases the possibility of seizures.
