Endogenous Amino Acids, L-Ornithine and L-Aspartate. After administration, it quickly breaks down into L-Ornithine and L-Aspartate. L-Ornithine being a substrate of urea cycle, converts toxic ammonia into non-toxic urea which is eliminated via kidneys, helping the diseased liver to carry out its normal function smoothly (detoxification). The process lowers the elevated level of ammonia in blood (hyperammonaemia) which is a common problem in most of the liver diseases. L-Aspartate is an essential component of citric acid cycle which liberates energy (ATP), and thus helps in regeneration of damaged liver cells.
