Abstract: A nasal drug delivery system delivering aerosolized medication through the nose of a user includes a nasal mask with a concave wall having an upper portion widening to a base portion, a sealing member surrounding an edge of the wall such that the nasal mask defines a sealed chamber in fluid communication with the nasal passages of the user, a port providing fluid communication with the chamber, the port being positioned in the upper portion of the nasal mask, and an aerosolizer device connected to the port of the nasal mask thereby delivering an aerosolized medication to the chamber. The aerosolized medication delivered to the chamber enters the nasal passages during a normal inhalational breathing pattern of the user.
