USE OF L-ARGININE IMMOBILISED ON ACTIVATED CARBON FOR PHARMACOLOGICAL CORRECTION OF ENDOTHELIAL DISFUNCTION

For the first time a complex of L-arginine sodium salt of sulfate of cellulose acetate on activated carbon. To investigate the processes of sorption-desorption of L-arginine in a model environment. In animal experiments it was shown that granulirovannye the form of a combined preparation in dosages of 30 mg/kg, 70 mg/kg and 200 mg/kg exhibits a pronounced anti-hypertensive, endothelioprotecive and cardioprotective activity in a dosage of 200 mg/kg.
