Ophthalmic solution

摘要

Provided is an ophthalmic solution capable of suppressing the adsorption of hexamethylene biguanide, which is used in ophthalmic solutions as an antiseptic component, on a soft contact lens and ophthalmic solution container. The ophthalmic solution contains specific ratios of: (A) hydroxypropyl methylcellulose which comprises 28.0-30.0 mass% of methoxy groups and 7.0-12.0 mass% of hydroxypropoxy groups, relative to the total amount of the hydroxypropyl methylcellulose, and has a methoxy group/hydroxypropoxy group ratio by mass of 2.5-4.0 and a 2 mass% aqueous solution of which shows a viscosity of 50-4000 mPa·s at 20
