Quick Answer: What is the mechanism of action of lorazepam?

Lorazepam binds to benzodiazepine receptors on the postsynaptic GABA-A ligand-gated chloride channel neuron at several sites within the central nervous system (CNS). It enhances the inhibitory effects of GABA, which increases the conductance of chloride ions into the cell.

How does lorazepam work in the brain?

How does lorazepam work? Lorazepam belongs to a group of medicines called benzodiazepines. It works by increasing the levels of a calming chemical, gamma-amino-butyric-acid (GABA), in your brain.
