    摘要: The present invention is directed to an ophthalmic composition in the form of a topical aqueous solution consisting essentially of an 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 optionally a 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.

    摘要: The present invention is directed to an ophthalmic composition in the form of a topical aqueous solution consisting essentially of an 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.
