IP No. 592775 The disclosure relates to pharmaceutical composition in form of a solution, comprising a polyalcohol of the formula 1: (H-C-OH)a(HO-C-OH)b(H-C-H)c, wherein a, b, c are integers, wherein a+b is at least 2, c is selected from 0, 1 or a number in the range of 2 to a+b, in addition with one or more aldehyde groups provided that they form (cyclic) acetals with one of the hydroxy groups or one or more keto groups optionally as acetal with one of the hydroxyl groups, optionally in addition to one or more carboxylic acid groups if the polyalcohol is a cyclic acetal or acetal, or a polymer, polyether or polyester thereof, provided that the polyalcohol exists as a polymer, polyether or polyester with at least two units of formula 1 if a+b is 2 or 3; and octenidine or pharmaceutical salts thereof provided that i) the solution has a NaCl concentration of less than 0.1% (w/v); and/or ii) if the polyalcohol is a monosaccharide it is selected from the group consisting of an aldopentose, a ketose, galactose, fructose, fucose, ribose, deoxyribose, and deoxyglucose. The disclosure also relates to the use of octenidine and the polyalcohol of formula 1 in the manufacture of a medicament for the treatment of wounds or burns, particularly to the skin or a mucous membrane and in the treatment or prophylaxis of infections. Also disclosed is a carrier soaked in the pharmaceutical composition for use in its administration.
