USPTO Abstract

The present application provides compositions, methods, and dispensers for topical delivery of ophthalmological active pharmaceutical ingredients (APIs). In one example, a composition is provided comprising an active pharmaceutical ingredient soluble in MCT wherein the API is not atropine or a salt thereof; a medium chain triglyceride (MCT); and a semi-fluorinated alkane compound. In another example, a nano-emulsion is provided comprising about an active pharmaceutical ingredient soluble in MCT; a medium chain triglyceride (MCT); and a semi-fluorinated alkane compound, wherein the nano-emulsion has a droplet particle size D90 of less than about 100 nm. Dispensers containing the compositions are also provided and include glass and polyethylene terephthalate dispensers or containers. Methods of using the compositions are also provided and include a method for treating an ocular condition in a subject comprising administering the compositions or nano-emulsions to an eye of the subject.
