Pharmacological properties.

Pharmacodynamics. The medicinal product is a partial (incomplete) selective agonist of the GABA_A receptor complex. It belongs to the group of benzodiazepine derivatives. It exerts pronounced sedative, anxiolytic, moderate muscle relaxant, and anticonvulsant effects; enhances the effects of sedatives, narcotic drugs, neuroleptics, and ethanol. A distinctive feature of the drug's sedative action is its ability to increase the duration of not only slow-wave sleep but also paradoxical sleep, with an unchanged number of episodes, making the sedative effect of the drug more physiological.

Pharmacokinetics. The drug is rapidly absorbed in the gastrointestinal tract, bioavailability is about 80%, half-life is 10–14 hours (the drug can be classified as an agent with intermediate duration of action). It is excreted via renal and biliary pathways in the form of an active metabolite – 3-hydroxy derivative.

Interaction with other medicinal products and other forms of interaction.

Alcohol should not be consumed during treatment with this medicinal product due to the possibility of psychomotor inhibition and respiratory depression. Concomitant use of this medicinal product with phenothiazine neuroleptics should be avoided because of the potentiation of respiratory depressant effects. It should be noted that cimetidine may increase blood concentrations of benzodiazepines (except oxazepam and lorazepam) by up to 50% by slowing their metabolism and clearance. High doses of caffeine, including in beverages, may reduce the therapeutic effect of the medicinal product.
