Pharmacology: AMINOLEBAN normalized the pattern of free amino acids in the plasma and brain, improved serotonin metabolism in the brain and corrected a sleep-wakefulness pattern in a rat model of chronic hepatic insufficiency which underwent a portacaval shunt operation.
When infused to portacaval-shunted rats loaded with ammonia, AMINOLEBAN improved EEG pattern and corrected amine metabolism in the brain as evidenced by correction of the free amino acid pattern in the plasma and brain and by suppression of an increase of the false neurotransmitter octopamine.
