    • Topical ophthalmic medicament delivery system combining an aqueous ophthalmic gel suspension at a pH equal to or greater than 7.5 and an osmotic pressure of from 10 to about 400 mOsM containing a pharmaceutically effective mount of one or more ophthalmic medicaments of from about 0.05% to about 10% by weight, based on the total weight of the suspension, of a carboxyl-containing polymer prepared by polymerizing one or more carboxyl-containing monoethylenically unsaturated monomers and less then about 5% by weight of a cross-linking agent. The systems have a viscosity of from about 1,000 to about 30,000 centiposes prior to administration to the eye and remain a gel in the eye for a prolonged period of time allowing for the sustained release of one or medicaments such as amine containing antibiotics alone or in combination with cortiscosteroids.
    • 局部眼科药物递送系统,其组合pH为等于或大于7.5的水性眼用凝胶悬浮液和10至约400mOsM的渗透压,所述渗透压含有约0.05%至约10%的药学上有效的一种或多种眼科药物 基于悬浮液的总重量计,通过聚合一种或多种含羧基的单烯属不饱和单体和少于约5%重量的交联剂制备的含羧基聚合物。 该系统在施用于眼睛之前具有约1,000至约30,000厘泊的粘度,并且在眼睛中保持长时间的凝胶,从而允许单独或组合的一种或多种药物如含胺抗生素的持续释放 与皮质类固醇。
