Oligochitosan Сh10/85 with a molecular weight of 10 kDa and a deacetylation degree of 85% prevented the development of experimental venous thrombosis in guinea pigs after intravenous administration in a dose of 30 mg/kg. In a concentration of 0.005-0.5 mg/ml, oligochitosan Ch10/85 did not provoke hemolysis of human red blood cells in in vitro experiments. The antithrombotic effect of oligochitosan Ch10/85 that exhibits low anticoagulant activity (by two orders of magnitude lower than that of unfractionated heparin) can be associated with inhibition of platelet aggregation.
