Aminophenylbutyric acid (AFC) normalizes metabolic processes in the nerve cells of the brain. The active ingredient can be considered as a derivative of gamma-aminobutyric acid or as a derivative of beta-phenylethylamine. Aminophenylbutyric acid has nootropic activity, and as a derivative of GABA has anti-anxiolytic activity. Does not affect choline and adrenergic receptors.
The active ingredient reduces tension, anxiety, fear and improves sleep, so it is used to treat neuroses and before surgery. AFC lengthens and enhances the effect of sleeping pills, narcotic, neuroleptic and antiparkinsonian drugs.
AFC is deprived of anticonvulsant activity. The active substance lengthens the latent period of nystagmus and shortens its duration and severity. The active ingredient also reduces the manifestations of asthenia and vasovegetative symptoms, including headache, feeling of heaviness in the head, sleep disorders, irritability, emotional lability and increases mental performance. Psychological indicators (attention, memory, speed and accuracy of sensorimotor reactions) under the influence of AFC improve, in contrast to the influence of tranquilizers. Patients with asthenia and emotionally labile patients from the first days of therapy improve their subjective well-being, interest and initiative, motivation for activity.
