Compositions and methods for systemic delivery of polypeptides through the eyes are disclosed. The compositions include a systemically active polypeptide at a concentration such that the composition is substantially isotonic with tear fluid. The compositions may include a permeation-enhancing agent to aid systemic absorption of higher molecular weight polypeptides, as well as peptidase inhibitors. Therapeutically effective amounts of the polypeptide compositions can be administered to the eyes where the drug passes into the nasolacrimal duct and becomes absorbed into circulation.
