A nasal administration device especially configured and adapted to deliver a composition to a eustachian tube lumen of a human patient via the pharyngeal orifice thereof, said device comprising an administration housing and a delivery nozzle wherein: the administration housing is configured to contain the composition to be delivered therein and includes an alignment tab extending therefrom having a proximal and distal terminus, the proximal terminus of the tab depending from the administration housing and the distal terminus being especially shaped an configured to enable stable placement thereof upon the patient's nose at a bridge portion thereof; and the delivery nozzle being formed as a hollow tube and including a central bore with a longitudinal axis, a proximal and distal termini, both said termini including openings in fluid communication with said central bore, the central bore and said openings all demonstrating an equal, constant and continuous diameters, the distal terminus and distal portion of said nozzle being especially shaped and configured to facilitate placement thereof within a nostril of the patient and the proximal terminus of said nozzle being especially shaped and configured to enable mounting thereof upon the administration housing so as to provide fluid communication of the central bore and terminal openings of the nozzle with the composition contained within the administration housing, the diameter of the delivery nozzle being especially selected to further facilitate the nozzle forming and delivering a well focused collimated stream of compound upon activation of and resulting release of the composition from the device, wherein, when the delivery nozzle is placed within a patient's nostril while the alignment tab is positioned against the bridge portion of the patient's nose, the design, shape, dimensions, and position of said alignment tab stabilizes the device's position and causes the longitudinal axis of the central bore of the delivery nozzle to be aligned in such a manner so that, upon activation of the device, the collimated stream of compound emanating therefrom is directed towards the pharyngeal opening of the eustachian tube. the administration housing is configured to contain the composition to be delivered therein and includes an alignment tab extending therefrom having a proximal and distal terminus, the proximal terminus of the tab depending from the administration housing and the distal terminus being especially shaped an configured to enable stable placement thereof upon the patient's nose at a bridge portion thereof; and the delivery nozzle being formed as a hollow tube and including a central bore with a longitudinal axis, a proximal and distal termini, both said termini including openings in fluid communication with said central bore, the central bore and said openings all demonstrating an equal, constant and continuous diameters, the distal terminus and distal portion of said nozzle being especially shaped and configured to facilitate placement thereof within a nostril of the patient and the proximal terminus of said nozzle being especially shaped and configured to enable mounting thereof upon the administration housing so as to provide fluid communication of the central bore and terminal openings of the nozzle with the composition contained within the administration housing, the diameter of the delivery nozzle being especially selected to further facilitate the nozzle forming and delivering a well focused collimated stream of compound upon activation of and resulting release of the composition from the device, wherein, when the delivery nozzle is placed within a patient's nostril while the alignment tab is positioned against the bridge portion of the patient's nose, the design, shape, dimensions, and position of said alignment tab stabilizes the device's position and causes the longitudinal axis of the central bore of the delivery nozzle to be aligned in such a manner so that, upon activation of the device, the collimated stream of compound emanating therefrom is directed towards the pharyngeal opening of the eustachian tube.
