Acetyl glutamine is mainly used in traumatic brain coma, coma caused by neurosurgery, hepatic coma and hemiplegia, paraplegia, post-polio, neurological headache and lumbago. The pharmacological effect of acetylglutamine is that acetylglutamine is decomposed into glutamate and γ-aminobutyric acid after passing the blood-cerebrospinal fluid barrier, glutamate can participate in the information transmission of the central nervous system. γ-aminobutyric acid can antagonize the toxic effect of glutamate excitation, improve the metabolism of nerve cells, maintain the neural stress capacity and lower the blood ammonia, so as to improve brain function. The dosage is 100-600mg a day intramuscularly or intravenously.
