Abstract
An eye drop composition comprising a carboxyvinyl polymer and a monoterpene, and having a viscosity from 200 to 100,000 mPa·s. The monoterpene may be at least one selected from the group consisting of menthol, camphor and borneol. The carboxyvinyl polymer content may be from 0.001 to 10 w/v % with respect to the total volume of the eye drop composition, and the monoterpene content may be from 0.0001 to 1 w/v % with respect to the total volume of the eye drop composition.
Claims12
An eye drop composition comprising a carboxyvinyl polymer and a monoterpene, and having a viscosity from 200 to 100,000 mPa·s.
A method of improving liquid drip performance of an eye drop composition at the eye drop composition container opening, comprising adding a monoterpene to an eye drop composition comprising a carboxyvinyl polymer to prepare an eye drop composition with a viscosity from 200 to 100,000 mPa·s.
A method of inhibiting viscosity reduction due to photoirradiation of an eye drop composition, comprising adding a monoterpene to an eye drop composition comprising a carboxyvinyl polymer to prepare an eye drop composition with a viscosity from 200 to 100,000 mPa·s.
A method of improving recovery from blurred vision after ocular instillation of an eye drop composition, comprising adding a monoterpene to an eye drop composition comprising a carboxyvinyl polymer to prepare an eye drop composition with a viscosity from 200 to 100,000 mPa·s.
10-11. (canceled)
A method of ocular instillation comprising a step of dropping a composition comprising a carboxyvinyl polymer and a monoterpene and having a viscosity from 200 to 100,000 mPa·s to an eye.
