Ophthalmic composition for suppressing degradation of soft contact lens

Abstract

The present invention provides: an ophthalmic composition which has an effect of suppressing the degradation of a soft contact lens, the ophthalmic composition containing a boric acid or a salt thereof and an epinastine or a salt thereof; and a pollen rupture inhibitor containing a specific concentration of a boric acid or a salt thereof and an epinastine or a salt thereof.

Description

technical field [0001] The present invention relates to an ophthalmic composition containing boric acid or a salt thereof and epinastine or a salt thereof for suppressing deterioration of soft contact lenses. It also relates to a pollen break inhibitor containing boric acid or a salt thereof and epinastine or a salt thereof in a concentration of 0.01 to 2% (w / v) of the boric acid or a salt thereof. Background technique [0002] Ophthalmic compositions containing solvents such as water, which are expected to be used repeatedly, require more than a certain level of anti-corrosion measures in order to prevent the growth of fungi and the like. Therefore, such an ophthalmic composition usually contains a preservative. For example, in the case of eye drops, benzalkonium chloride is often used as a preservative. Benzalkonium chloride is water-soluble, chemically stable, and has high antiseptic efficacy compared with other preservatives. However, benzalkonium chloride is known to...
