Abstract: A tears-resistant and enduring intraocular pressure lowing composition comprises an intraocular pressure lowering drug, a mucoadhesive polymer, a PH sensitive polymer, and a solvent. When a PH is less than or equal to 7.03, the intraocular pressure lowing composition is in a liquid form, when the PH is greater than 7.03, the intraocular pressure lowing composition is in a gel form. The gel form of intraocular pressure lowering composition is not easily washed out by tears, so when the intraocular pressure of an eye is normal, the intraocular pressure lowering composition dropped in the eye is in gel form, thereby the intraocular pressure lowering composition can be retained in the eye for a long time.
