  • Medicinal preparation for treatment of viral-etiology diseases
    Patent number: 4016289
    Abstract: A medicinal preparation for treatment of viral-etiology diseases contains the bisulphite compound of 2-fluorenonyl-glyoxal in combination with a pharmaceutical vehicle or unctuous base.A method of producing the bisulphite compound of 2-fluorenonyl-glyoxal, viz, the active principle of said medicinal preparation, consists in that fluorene is acylated by dichloroacetyl chloride in the presence of aluminum chloride and phosphoryl chloride in an organic solvent, the resultant 2-.omega.-dichloroacetylfluorene is oxidized by the salts of chromic acid in an acetic-acid medium at 50.degree.-90.degree. C into 2-.omega.-dichloroacetylfluorenone which is made to interact with morpholine at 50.degree.-98.degree. C to form 2-.omega.-dimorpholinoacetylflourenone, or otherwise, fluorenone is acylated by acetic anhydride in an organic solvent in the presence of aluminum chloride, the resultant 2-acetylfluorene is oxidized by chromic acid or by the salts thereof in an acetic acid medium at 50.degree.-90.degree.

  • Base for ophthalmological medicinal preparation on opthalmological medicinal film
    Patent number: 3978201
    Abstract: A base for ophthalmological medicinal preparations consists of a homopolymer of an amide of acrylic acid having a molecular weight from 30,000 to 1,000,000, and/or a copolymer of an amide of acrylic acid with unsaturated compounds, the molecular weight of the copolymer being from 20,000 to 500,000, and containing from 10 to 90 per cent acrylamide links.The ophthalmological medicinal film is an oblong plate, 6-9 mm long, 3-5 mm wide and 0.2-0.6 mm thick, of the homopolymer and/or copolymer acrylamide links from 10 to 90 per cent, and an active medicinal ingredient, viz., 3-ethyl-4(1-methyl-5-imidazolyl)-tetrahydrofuran-2-one or atropine, or 3-methoxy-6-sulphanilan idopyridazine, or .beta.-dimethylamino-ethyl-p-butylaminobenzoate, or neamine, or 5-iodo-2-desoxyuridine.

  • Base for ophthalmological medicinal preparations and on ophthalmological medicinal film
    Patent number: 3935303
    Abstract: A base for ophthalmological medicinal preparations consists of a homopolymer of an amide of acrylic acid having a molecular weight from 30,000 to 1,000,000, and/or a copolymer of an amide of acrylic acid with unsaturated compounds, the molecular weight of the copolymer being from 20,000 to 500,000, and containing from 10 to 90 percent acrylamide links.The ophthalmological medicinal film is an oblong plate, 6-9 mm long, 3 - 5 mm wide and 0.2 - 0.6 mm thick, of the hompolymer and/or copolymer and an active medicinal ingredient, viz., 3-ethyl-4(1-methyl-5-imidazolyl)-tetrahydrofuran-2-one or atropine, or 3-methoxy-6-sulfanilam idopyridazine, or .beta.-dimethylamino-ethyl-p-butylaminobenzoate, or neamine, or 5-iodo-2-desoxyuridine.
