Patent attributes
The invention describes ophthalmic pharmaceutical formulations comprising pharmaceutical ingredients to address DED symptoms. In one aspect of the invention, an ophthalmic pharmaceutical formulation comprises: 1) lubricity-promoting ingredient(s) such as those listed in the FDA over the counter (OTC) monograph for ophthalmics as demulcents and 2) surfactant(s) that solubilize lipids, assist in lubrication, and assist in easily spreading over hydrophobic surfaces; and/or 3) lipid and/or plant oil ingredient(s) that assist in film formation and the spreading of tear fluid while promoting (or at least not inhibiting) lubrication; and/or 4) mucoadhesive and viscosity promoting polymer(s) that demonstrate shear thinning flow behavior. The pharmaceutical ingredients and osmoprotectant/tonicity ingredients are combined with ingredients that provide direct to the eye nutritional support that is comprehensive in nature. The total nutritional approach uses metabolically important tear fluid amino acids, vitamins, and both fatty acids/triglycerides and sugar molecules as energy sources. The invention results in both improved eye health and improved dry eye patient comfort.
