Pharmacological Action

A nootropic agent, it possesses neurometabolic, neuroprotective, and neurotrophic properties. It increases the brain’s resistance to hypoxia and the effects of toxic substances, stimulates anabolic processes in neurons, combines a moderate sedative effect with a mild stimulating effect, has an anticonvulsant action, and reduces motor excitability while regulating behavior.

It increases mental and physical performance. It helps normalize GABA levels in chronic alcohol intoxication and subsequent ethanol withdrawal. It exhibits an analgesic effect.
