Claims27
A topical ophthalmic composition comprising a gelling polysaccharide and a finely-divided drug carrier substrate, wherein the concentration of said gelling polysaccharide allows the composition to be administrable as a drop which gels upon instillation to the eye.
A method of delivering an ophthalmic agent to the eye which comprises topically administering a composition comprising:
- an ophthalmic agent, a gelling polysaccharide, and a finely-divided drug carrier substrate, wherein the concentration of said gelling polysaccharide allows the composition to be administrable as a drop which gels upon instillation to the eye.
