Abstract
The present invention is directed to an aqueous dispersion of an ophthalmic drug and a high molecular weight polymer which forms a highly viscous gel and can be used to prolong the duration of activity of the ophthalmic drug when the gel is applied into the conjunctival sac of the eye. The ophthalmic drug-containing gel composition has prolonged retention time in the eye and remains in contact with the surface of the eye for an extended period of time.
