  • Patent number: 6306843
    Abstract: In a method for producing stable acetylsalicylic acid solutions with pharmaceutically acceptable non-aqueous organic solvents such as, e.g., dimethylisosorbide, propylene glycol or diethylene glycol monoethyl ether, 0.005-2% by weight of a cyclic acid imide and/or 0.005-2% by weight of a sulfaminic acid as well as, preferably, 1-40% by weight, based on the weight of the solution, of a compound of the general formula are added to the solution. In the general formula, R1 represents H, CH3 or C2H5, n=0 or 1, and R2 represents H or one or more lower alkyl, lower alkyloxy or lower alkenyl residues having 1 to 5 carbon atoms.

  • Patent number: 4869899
    Abstract: A pharmaceutical preparation contains an active ingredient added to polyalcohols, such as polyethylene and/or polyalkylene glycols and/or oxystearates of glycerine-polyethyleneglycol and/or partial fatty acid esters of sorbitan or polyhydroxyethylenesorbitan and/or polyvinylpyrrolidone and/or polyvinylalcohols and/or fatty alcohol ethers of polyhydroxyethylene or fatty acid ester of polyhydroxyethylene and/or condensates of polyhydroxyethylene-polyhydroxypropylene, and especially dissolved in nifedipine in a weight ratio between 1:2 and 1:25. The composition contains ethanol as well, in an amount ratio between 1:25 and 1:4 of nifedipine:ethanol and can be sprayed with a propeller gas.
