Pharmacological action

Pharmacological action - hypoazotemic. Pharmacodynamics Reduces the increased concentration of ammonia in the body, in particular with liver diseases. The effect of the drug is associated with its participation in the ornithine Krebs urea cycle (the formation of urea from ammonia). Ornithine acts as a catalyst for the enzymes carbamoylphosphate synthetase and ornithine carbamoyl transferase, and is also the basis for the synthesis of urea. In addition, the drug activates the ornithine urea formation cycle, which also helps reduce ammonia levels. Promotes the production of insulin and growth hormone. Improves protein metabolism in diseases requiring parenteral nutrition. In vivo pharmacokinetics form 2 active metabolites: aspartate and ornithine, having a short T1 / 2 of 0.3–0.4 hours, are excreted by the kidneys through a urea cycle. A small part of aspartate is excreted by the kidneys unchanged.
