  • Patent number: 5795913
    Abstract: The present invention is directed to an ophthalmic composition in the form of a topical aqueous solution consisting essentially ofan ophthalmologically active agent containing basic groups,an ion sensitive, hydrophilic polymer containing acidic groups in an amount of 0.004 to 1.5% by weight,at least one salt selected from the group of inorganic salts and buffers in a total amount of from 0.01 to 2.0% by weight,and optionally a wetting agent and a preservative, the ratio between salt and polymer being such that the solution exhibits a viscosity of less than 1000 mpas, and the pH of the solution is 4.0 to 8.0. The composition contains a sufficient amount of polymer to provide for a controlled absorption of the drug into the eye, its viscosity having been reduced to provide for better handling characteristics.

  • Patent number: 5776499
    Abstract: The object of the invention is a process for preparing a clodronate preparation. The process is characterized in that clodronate is crystallized as disodium clodronate tetrahydrate from an aqueous solution of disodium clodronate; the resulting disodium clodronate tetrahydrate is dry granulated by compressing in such a way that the crystal structure of the disodium clodronate tetrahydrate is preserved and by crumbling and screening the mass to granules of a sutiable size, the dry granulated disodium clodronate tetrahydrate is optionally mixed with suitable excipients, such as filling agents and gliding agents and, if necessary, disintegrants.

  • Patent number: 5710182
    Abstract: The present invention is directed to an ophthalmic composition in the form of a topical aqueous solution consisting essentially ofan ophthalmologically active agent,an ion sensitive, hydrophilic polymer in an amount a of 0.004 to 1.5% by weight,at least one salt selected from the group of inor ganic salts and buffers in a total amount of from 0.01 to 2.0% by weight,a wetting agent in an amount of 0 to 3.0% by weight,a preservative in an amount of 0 to 0.02% by weight,water, and optionallya pH regulating agent in an amount sufficient to give a pH of 4.0 to 8.0 to the composition,the ratio between salt and polymer components being such that the solution exhibits a viscosity of less than 1000 mPas. The composition contains a sufficient amount of polymer to provide for a controlled absorption of the drug into the eye, its viscosity having been reduced to provide for better handling characteristics.
