Pharmacological effect
Anxiolytic (tranquilizer). Etifoxine hydrochloride belongs to benzoxazine derivatives. As an anxiolytic agent, etifoxine has an autonomous regulatory effect. In vitro and in vivo studies in rats and mice, it was shown that the etipoxin anxiolytic activity is due to its dual mechanism of action (direct and mediated) on GABA-A receptors, which improves GABA-ergic transmission of the impulse. With a direct effect on the GABA-A receptor by allosteric modulation, etifoxine binds predominantly to the β2 or β3 receptor subunits; Studies have shown that etifoxine binds to the GABA-A receptor at sites other than the benzodiazepine binding site. Indirect action is provided by increasing the synthesis of neurosteroids (by activating the mitochondrial protein translocator), such as allopregnanolone, which is also a positive aplosteric modulator of the GABA-A receptor.
Pharmacokinetics
Absorption: After oral administration, the drug is rapidly absorbed from the gastrointestinal tract. The time to reach Cmax in the blood is 2-3 hours. Distribution: It penetrates the placental barrier. Metabolism: It is rapidly metabolized in the liver to form several metabolites. One of the metabolites, diethylethoxoxin, is active. Excretion: T1 / 2 of etipoxin is about 6 hours, T1 / 2 of the active metabolite is 20 hours. It is eliminated mainly with urine as metabolites and in small quantities in unchanged form; also excreted in the bile.
Indications
Treatment of psychosomatic manifestations of anxiety.
