Abstract

According to the aqueous ophthalmic composition comprising (A) polyoxyethylene castor oil and (B) sesame oil, defoaming time is reduced, preservative efficacy is enhanced, and photostability is improved.

Description

technical field [0001] The present invention relates to an aqueous ophthalmic composition. More specifically, the present invention relates to an aqueous ophthalmic composition with reduced defoaming time, enhanced preservative efficacy and improved photostability. Background technique [0002] In the field of ophthalmology, solubilizers are added to various formulations. In particular, in aqueous ophthalmic compositions, various solubilizers are added to facilitate dissolution of bioactive components and additives and the like having relatively low water solubility. Surfactants can be exemplified as solubilizers used in the field of ophthalmology. It is known that polyoxyethylene castor oil is a nonionic surfactant, and adding it to an aqueous ophthalmic composition helps dissolve other components (Patent Document 1). [0003] Aqueous compositions containing surfactants are known to be prone to foaming, and foaming occurs when subjected to vibration or impact during prod...
