Directional use

Abstract

Disclosed is a method for oral administration of a liquid containing an active substance to a subject for improved absorption into the subject's bloodstream. It includes the steps of providing a delivery device containing the liquid and having a mouthpiece for directing the liquid in a defined direction during delivery; directing the mouthpiece toward a localized area of the subject's mouth being especially suitable for relatively increased uptake and relatively faster onset of action of the active substance; and delivering a measured amount of the liquid directly to the area using the device. Also disclosed is a spray device that includes a container capable of holding a liquid containing an active substance, and a mouthpiece constructed to dispense the liquid in a defined direction and directly to a localized area of a subject's mouth, the localized area being the oral vestibule.
