Pharmachologic effect

Anxiolytic, hypnotic, sedative, anticonvulsant, muscle relaxant. Enhances the inhibitory effect of GABA on the transmission of nerve impulses. Stimulates benzodiazepine receptors located in the allosteric center of postsynaptic GABA receptors of the ascending activating reticular formation of the brain stem and intercalated neurons of the lateral horns of the spinal cord; reduces the excitability of the subcortical structures of the brain (limbic system, thalamus, hypothalamus), inhibits polysynaptic spinal reflexes. The anxiolytic effect is due to the effect on the amygdala complex of the limbic system and is manifested in a decrease in emotional stress, easing anxiety, fear, anxiety. The sedative effect is due to the effect on the reticular formation of the brain stem and non-specific nuclei of the thalamus and is manifested by a decrease in the symptoms of neurotic origin (anxiety, fear). The productive symptoms of psychotic genesis (acute delusional, hallucinatory, affective disorders) are practically not affected, rarely there is a decrease in affective tension, delusional disorders. Hypnotic effect is associated with inhibition of the cells of the reticular formation of the brain stem. Reduces the effects of emotional, vegetative and motor stimuli that violate the mechanism of falling asleep. The anticonvulsant effect is realized by enhancing presynaptic inhibition, suppresses the spread of the convulsive impulse, but the excited state of the focus is not removed. The central muscle relaxant effect is due to inhibition of the polysynaptic spinal afferent inhibitory pathways (to a lesser extent, monosynaptic). Direct inhibition of motor nerves and muscle function is also possible.
