Heparetta® (Geparetta)

Ademetionine belongs to the group of hepatoprotectors, it also has antidepressant activity. It has choleretic and cholekinetic effect, detoxification, regenerating, antioxidant, antifibrozing and neuroprotective properties. Replenishes the deficit S-adenosyl-L-metionine (ademethionine) and stimulates its production in the body, is contained in all media of the body. The highest concentration of ademetionine is found in the liver and brain. Performs a key role in the metabolic processes of the body, takes part in important biochemical reactions: transmethylation, transulfurization, transamination. In the reactions of transmethylation ademethionine donates a methyl group for the synthesis of phospholipids of cell membranes, neurotransmitters, nucleic acids, proteins, hormones, etc. In the transsulfation reactions ademethionine is the precursor of cysteine, taurine, glutathione (providing the oxidation-reduction mechanism of cellular detoxification), coenzyme acetylation (included in biochemical reactions of the tricarboxylic acid cycle and replenishes the energy potential of the cell).Increases the glutamine content in the liver, cysteine ​​and taurine in plasma; reduces the content of methionine in the serum, normalizing metabolic reactions in the liver. After decarboxylation, it participates in aminopropylation reactions, like the predecessor of polyamines-putrescine (the stimulator of cell regeneration and proliferation of hepatocytes), spermidine and spermine, which are part of the ribosome structure, which reduces the risk of fibrosis. Has a choleretic effect. Ademethionine normalizes the synthesis of endogenous phosphatidylcholine in hepatocytes, which increases the fluidity and polarization of membranes. This improves the function of hepatocyte-associated transport systems of bile acids and promotes the passage of bile acids into the biliary system. Effective with intrahepatic (intralobular and interlobular) variant of cholestasis (violation of synthesis and current of bile). Ademethionine reduces the toxicity of bile acids in the hepatocyte, carrying out their conjugation and sulfation. Conjugation with taurine increases the solubility of bile acids and their removal from the hepatocyte. The process of sulphation of bile acids contributes to the possibility of their elimination by the kidneys, facilitates the passage through the membrane of the hepatocyte and excretion with bile.In addition, the sulfated bile acids themselves additionally protect the liver cell membranes from the toxic effect of non-sulphated bile acids (in high concentrations present in hepatocytes with intrahepatic cholestasis). In patients with diffuse liver disease (cirrhosis, hepatitis) with intrahepatic cholestasis syndrome ademethionine reduces the severity of skin itching and changes in biochemical parameters, incl. the level of direct bilirubin, the activity of alkaline phosphatase, aminotransferases, etc. Choleretic and hepatoprotective effects persist up to 3 months after discontinuation of treatment. Efficacy is shown for hepatopathies caused by various hepatotoxic drugs. The appointment of patients with opioid addiction, accompanied by liver damage, leads to regression of clinical manifestations of abstinence, improvement of the functional state of the liver and the processes of microsomal oxidation. Antidepressant activity manifests itself gradually, beginning with the end of the first week of treatment, and stabilized within 2 weeks of treatment.Effective in recurrent endogenous and neurotic depressions resistant to amitriptyline. Has the ability to interrupt recurrence of depression. The appointment in osteoarthritis reduces the severity of the pain syndrome, increases the synthesis of proteoglycans and leads to partial regeneration of the cartilaginous tissue.
