🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by binding to the benzodiazepine site on the GABA-A receptor complex in the brain. This enhances the inhibitory effect of GABA, the main calming neurotransmitter in the central nervous system. The result is an increase in chloride ion flow into neurons, which hyperpolarizes the cells and reduces their excitability. This leads to sedation, muscle relaxation, and sleep promotion. Unlike benzodiazepines, this medicine has a higher selectivity for the omega-1 subtype of the GABA-A receptor, which is thought to contribute to its more specific hypnotic effect with fewer muscle relaxant and anticonvulsant properties.
