What is L-Ornithine L-Aspartate Salt?

Ornithine aspartate was developed in Germany in the 1960s, and was first used clinically for the treatment of hangover and hepatic encephalopathy. With the accumulation of clinical application experience, ornithine aspartate has been more widely used in the treatment of liver diseases, and has achieved exact curative effects on hepatic encephalopathy, drug-induced liver damage, fatty liver, chronic hepatitis and other diseases , has been widely recognized by clinicians

Effects of L-Ornithine L-Aspartate Salt

  1. Ornithine Aspartate can significantly improve the clinical symptoms of patients with overt hepatic encephalopathy and mild hepatic encephalopathy, and can significantly reduce the blood ammonia content of patients. It can also effectively reduce blood ammonia and improve intelligence test indicators.
  2. Ornithine aspartate granules have a certain therapeutic effect on hepatic steatosis and hepatic inflammation, and show a better effect on improving hepatic steatosis in patients with moderate to severe fatty liver.
  3. Drug-induced liver injury Ornithine aspartate can significantly reduce the levels of ALT, AST, TBI1, GGT and ALT in patients with drug-induced liver injury.
  4. Ornithine aspartate is suitable for patients to take a long course of treatment, it is not easy to rebound after drug withdrawal, and has high safety.
  5. Ornithine aspartate gradually becoming the main therapeutic drug for the treatment of various liver diseaOrnithine aspartate can significantly improve liver damage caused by chemotherapy drugs and improve the therapeutic effect of tumor patients.
  6. Ornithine aspartate can prevent and treat postoperative liver damage and promote postoperative recovery of patients.

Effects of L-Ornithine L-Aspartate Pharmacological Effects

In vivo, ornithine aspartate acts on two major ammonia detoxification pathways—urea synthesis and glutamine synthesis—by producing two amino acids, aspartic acid and ornithine. Urea synthesis occurs in hepatocytes around the portal vein, and ornithine acts as a catalyst and substrate for two enzymes, ornithine carbamoyltransferase and carbamoyl-phosphate synthase, and participates in the process of urea synthesis from ammonia. . Glutamine synthesis occurs in hepatocytes around the hepatic veins, and especially in pathological conditions, aspartate and other dicarboxylates, such as metabolites of ornithine, are taken up by hepatocytes around the hepatic veins , synthesizes glutamine and combines ammonia in the form of glutamine. In both physiological and pathological states, glutamine acts as an amino acid that binds ammonia, which not only allows ammonia to be excreted in a non-toxic form, but also activates important Urea cycle and glutamine exchange between cells. Under physiological conditions, the role of ornithine aspartate is not limited to urea synthesis. Animal experiments have found that increased glutamine synthesis has the effect of reducing blood ammonia levels. Some clinical trials have also found that they can improve the ratio of branched-chain amino acids to aromatic amino acids. effect. In addition, due to the promoting effect of aspartic acid on the metabolic process of the tricarboxylic acid cycle in the hepatocytes, the energy production in the hepatocytes is promoted, so that the function of the damaged hepatocytes can be restored.

Clinical Application of L-Ornithine L-Aspartate Salt

Ornithine can activate the key enzymes in the process of urea synthesis – ornithine carbamoyltransferase and carbamoyl phosphate synthase, and promote ammonia Metabolism to achieve detoxification of blood ammonia, aspartic acid as a substrate can generate glutamic acid and oxaloacetic acid, glutamine is the detoxification product of ammonia, and it is also the storage and transportation of ammonia. Oxaloacetic acid participates in the tricarboxylic acid cycle, promotes the production of energy in liver cells, repairs and regenerates damaged liver cells, and restores liver function. Ornithine aspartate can effectively improve liver function, reduce blood ammonia, and synergistically reduce ammonia with lactulose and ofloxacin, thereby significantly improving the cure rate of hepatic encephalopathy, which is worthy of clinical application.
