SUBSTANCE : invention relates to a pantohematogen-base medicinal formulation for external using that comprises the following components, wt.-% : dry pantohematogen, 0.01-6; polymeric gel-forming composition, 0.1-20, and water, the balance. Proposed medicinal formulation provides using pantohematogen an aqueous solution without addition of alcohol and therefore it can be used in cases wherein alcohol-containing formulations are contraindicative - in burns of different degree, small skin damages and others and can be used in treatment of patients showing intolerance to alcohol-containing preparations. Method for preparing the pantohematogen medicinal formulation for external using involves preparing "dry" pantohematogen aqueous solution in the ratio limits pantohematogen : water = (1 : 50)-(1 : 200) by weight and solution is kept under normal conditions for 1 h and filtered. Additionally an aqueous solution of rare-linked polymer is prepared in the ratio = (1 : 10)-(1 : 200) and an aqueous solution of neutralizing agent in the amount necessary for providing slightly alkaline medium of final solution. In the volume ratio of pantohematogen aqueous solution and rare-linked polymer in the ranges = (3 : 1)-(1 : 10) components are mixed and stirred to obtain the homogenous solution. Then neutralizing agent aqueous solution is added to a mixture and stirred to obtain homogenous solution with slightly alkaline reaction (pH = 6-8). The advantage of proposed technology in preparing the medicinal formulation involves its simplicity and providing prolonged fitness period.
EFFECT : improved preparing method.
