Insomin is a type of benzodiazepine drug. It is a powerful hypnotic drug which possesses strong sedative, anxiolytic, amnestic, anticonvulsant, and skeletal muscle relaxant properties.

How Insomin works
Insomin belongs to a group of medicines called benzodiazepines. This drug affects central benzodiazepine receptors, which are associated with inhibitory GABA (gamma amino butyric acid)receptors, leading to enhanced GABA binding activity. GABA is a major neurotransmitter in the brain, which causes somnolence, relaxation of muscles, a decrease in anxiety and general central nervous system depression. Insomin has anticonvulsant properties that may be attributed to its ability to bind to voltage-dependent sodium channels. Sustained repetitive firing seems to be limited by benzodiazepines effect of slowing recovery of sodium channels from inactivation.
