FIELD: medicine. SUBSTANCE: crystalline heparin should be frozen in chamber in the flow of inert gas at the temperature of (-15 C) - (-25 C). Then crystalline heparin particles should be dissolved in water for injections at addition of benzyl alcohol and sodium chloride at pH = 5.0-7.5. Then sterilization should be conducted followed by ampoulating. The present innovation enables to increase stability of the preparation suggested. EFFECT: higher efficiency. 2 ex
