Abstract:
The present invention provides an aqueous ophthalmic composition containing (A) a terpenoid, (B) zinc chloride, and (C) at least one member selected from the group consisting of cellulose-based polymeric compounds, vinyl-based polymeric compounds, polyethylene glycols and dextran. According to the present invention, an aqueous ophthalmic composition is provided in which adsorption of the terpenoid to a container can be inhibited, thereby making it possible to inhibit the reduction in the terpenoid content for a long period of time, the aqueous ophthalmic composition having some excellent actions such as an inhibitory action for histamine release, and an inhibitory action for discharges from the eyes.
