    摘要: PURPOSE: To obtain a drug composition containing a penem derivative FCE 22101 and ceftizoxime, exhibiting synergistic antibacterial action and useful for the treatment of the infection of respiratory system, urinary duct, etc. CONSTITUTION: The objective composition is produced by using (5R,6S)-2- carbamoyloxymethyl-6-([(1R)-hydroxyethyl]-penem-2-carboxylic acid (FCE 22101) or its salt or ester and 7-[2-(2-aminothiazol-4-yl)-2-methoxyiminoacetamido]-3- cephem-4-carboxylic acid (ceftizoxime) or its salt or ester as active components and forming to a drug preparation by conventional method. The weight ratio of FCE 22020/ceftzoxime is 10:1 to 1:3 in terms of pure antibiotic equivalent. The daily administration dose of the composition is 1-3g for adult (70kg body weight).

    摘要: PURPOSE: To obtain a matrix comprising a drug, capable of keeping the release of the drug at a constant rate and nonuniformly distributed therein by immersing a specific cross-linked siloxane matrix in a solution containing the drug dissolved in a solvent, swelling the matrix and then drying the swollen matrix. CONSTITUTION: This siloxane matrix nonuniform in internal distribution of a drug is prepared by mixing an uncross-linked siloxane base polymer, preferably a polymer having methylvinyl polysiloxane units with a curing agent (e.g. a polymer having the methylvinyl polysiloxane units) and a catalyst, as necessary, a filter and/or an additive, arranging the resultant mixture in a metallic mold, cross-linking the mixture for preferably 20-60hr, preparing a siloxane matrix, immersing the prepared siloxane matrix in a solution containing the drug (e.g. methylhydroxyprogesterone acetate) dissolved in a low-boiling solvent such as methylene chloride or cyclohexane, swelling the matrix and then drying the swollen matrix.
