How Midazolam works
Midazolam is a short-acting benzodiazepine, a category of medicine widely used for its sedative, muscle relaxant, and anxiolytic (anti-anxiety) properties.
The medicine works by potentiating the effects of gamma-aminobutyric acid (GABA), which is an inhibitory neurotransmitter in the brain. Simply put, it boosts the activity of GABA, leading to increased inhibition or slowing down of the central nervous system. This results in desired outcomes such as sedation (inducing sleepiness), reduction of anxiety, and muscle relaxation. Additionally, this mechanism of action contributes to its anticonvulsant effects, helping to control seizures by calming excessive electrical nerve activity in the brain.
