Preparation of ophthalmic compositions

摘要

A method of preparing a polymeric demulcent-containing ophthalmic composition. The method includes immersing a polymeric demulcent in water or in an aqueous solution containing one or more ingredients, agitating the water or solution at 25 to 45° C. until the polymeric demulcent is dissolved to form a polymeric demulcent-containing solution, and optionally adding one or more other ingredients to the polymeric demulcent-containing solution.
