Abstract
1414182 Opthalmic bases and compositions VSESOJUZNY NAUCHNO-ISSLEDOVATELSKY I ISPYTATELNY INSTITUT MEDITSINSKOI TEKHNIKI 24 Oct 1972 48884/72 Heading A5B [Also in Division C3] A therapeutic preparation for use in opthalmolegy comprises a polymeric base soluble in biological liquid and consisting of a homopolymer of an amide of acrylic acid having a molecular weight of 30000 to 1000000 and/or a copolymer of such amide having a molecular weight of 20000 to 500000 and containing 10 to 90% of acrylamide units, and an opthalmic medicament in the base. In examples the polymers used are polyacrylamide and copolymers of acrylamide with N-vinyl pyrrolidone or N- vinyl caprolactam and vinyl acetate or ethyl or butyl acrylate and the active principle is atropine, #-dimethylamino-ethyl-p-butylaminobenzoate, 5-iodo-2-desoxyuridine, 3-methoxy-6- sulphanil-amidopyridazine, 3-ethyl-4(1-methyl- 5-imidazolyl)-tetrahydrofuran-2-one or neamine. The preparation may be formed as a film.
