ABSTRACT:
There is provided a pharmaceutical composition suitable for topical administration to an eye, the composition comprising (a) a pharmacologically effective concentration of an active agent and (b) a combination of at least two ophthalmically compatible polymers comprising a novel gum system. In preferred embodiments of the present invention, the compositions increase the retention time of the active agent in the eye, when compared to compositions with other gums or gum systems.
