Efficiency of inosine glycyl-cysteinyl-glutamate disodium and pyridoxine in acute poisoning by unsymmetrical dimethylhydrazine

Effectiveness of pyridoxine hydrochloride and inosine glycyl-cysteinyl-glutamate dinatrium (molixan) in monotherapy and in combination in acute poisoning by unsymmetrical dimethylhydrazine on survival, blood biochemical indicators and the state of plasma coagulation hemostasis was assessed. Unsymmetrical dimethylhydrazine was administered intraperitoneally at a dose of 115 mg/kg (LD50) once. Drugs under examination were also admistered intraperitoneally: pyridoxine hydrochloride in a dose of 50 mg/kg once, 30 minutes after the administration of unsymmetrical dimethylhydrazine, the inosine glycyl-cysteinyl-glutamatedinatrium (molixan) in a dose of 60 mg/kg seven times: 30 minutes after the administration of unsymmetrical dimethylhydrazine, and then daily for 6 days. Biochemical parameters of blood, plasma coagulation hemostasis, were evaluated 7 days after the administration of unsymmetrical dimethylhydrazine. The use of pyridoxine as a monotherapy and in combination with molixan prevents death of experimental animals and the development of convulsive syndrome. In addition, the combination of molixan with pyridoxine eliminates the development of toxic lesions of liver that is having hepatoprotective effect. The efficiency of molixan as hepatoprotector, apparently, related to the fact that in its structure it is a combined preparation containing the peptide and purine components. The peptide component (glycyl-cysteinyl-glutamate dinatrium) is a pharmacological analogue of oxidized glutathione, purine is represented by inosine. Oxidized glutathione has cytoprotective activity, inhibits the cytolysis of hepatocytes, and reduces the severity of inflammatory process during toxic damage of liver cells by the products of metabolism of xenobiotics. Inosine also has hepatoprotective properties. As a precursor to the synthesis of adenosine triphosphoric acid and nucleotides, it stimulates a number of metabolic processes in body, supports energy balance in various tissues, particularly in liver and myocardium.
