FIELD: medicine, pharmaceutics.SUBSTANCE: group of inventions refers to medicine and veterinary science. A pharmaceutical or veterinary paste-like composition for treating a bacterial infection in a recipient's body in need thereof contains: a) an effective amount of a therapeutic agent which is 3-(cyclopropylmethoxy)-5,5-dimethyl-4-(4-methylsulphonyl)phenyl)- 5H-furan-2-one or 3-(cyclopropylethoxy)-5,5-dimethyl-4-(4-methylsulphonyl)phenyl)-5H-furan-2-one, or pharmaceutically accepted salts or hydrates of these compounds； b) colloidal silicon dioxide； c) a viscosity modifier specified in PEG 200, PEG 300, PEG 400, PEG 600, monoethanol amine, triethanol amine, glycerine, propylene glycol, polyoxyethylene sorbitan monooleate or poloxamers； d) if required, an absorbent； e) if required, a colouring substance； and f) a carrier. Methods of treating inflammation, pain or fever, rheumatoid arthritis or osteoarthritis involve introducing an effective amount of the paste-like composition in a recipient in need thereof. The group of inventions also involves a method for preparing the paste-like composition.EFFECT: group of inventions provides the paste-like composition which does not require heating or cooling in the process of preparation and shows low or no sensitivity to deviations in the process of preparation and shows low or no sensitivity to temperature that enables long storage with minimum physical or chemical changes of the paste-like composition.16 cl, 12 tbl, 9 ex, 7 dwgГруппа изобретений относится к области медицины и ветеринарии.
