An aerosolization system includes a container that is configured to deliver a unit dosage of a liquid when squeezed a single time. The system also includes an aerosolizer that is constructed of a housing defining a mouthpiece, and an aerosol generator disposed in the housing. The aerosol generator includes a vibratable membrane having a front face and a rear face, and a vibratable element used to vibrate the membrane. Further, the housing includes an opening that is adapted to receive a unit dosage of the liquid from the container. The opening provides a liquid path to the rear face of the vibratable membrane.

1. A method comprising: providing a container comprising a container body and a nozzle, the container being configured to deliver a unit dosage of a liquid from the nozzle when manually actuated a single time, wherein the nozzle has a central axis;providing an aerosolizer comprising: a housing defining a mouthpiece, the housing having an opening configured to receive the unit dosage of liquid;a cover movably attached to the housing so as to be movable between an open position where the opening is exposed and a closed position where the opening is covered;an aerosol generator disposed entirely within the housing, wherein the aerosol generator comprises a vibratable membrane having a front face, a rear face and a plurality of apertures that extend between the front face and the rear face, and a vibratable element used to vibrate the membrane, wherein the vibratable element is annular in geometry, surrounds the apertures and is planar along a lateral plane;moving the cover to the open position;positioning the nozzle over the opening using a human hand such that the central axis of the nozzle is perpendicular to the lateral plane;manually actuating the container the single time with the human hand while the container is outside the housing to dispense the unit dosage of liquid from the nozzle and into the opening, whereupon the entire unit dosage of liquid flows directly through the opening along a flow path that is aligned with the central axis and to the rear face of the vibratable membrane where it is stored on the rear face until the vibratable element is energized to aerosolize the entire unit dosage of liquid stored on the rear face. 2. A method as in claim 1, further comprising actuating the aerosol generator to aerosolize the liquid. 3. A method as in claim 1, wherein the container body has a proximal end, a distal end, and wherein the nozzle is positioned at the distal end, wherein the container further comprises a tip seal and a spring that biases the tip seal in a normally closed position, wherein the actuation of the container creates a sufficient pressure to move the tip seal and to deliver the unit dosage of the liquid from the nozzle, and wherein after dispensing, the tip seal closes to prevent the liquid from moving back into the container. 4. A method as in claim 1, wherein the opening comprises a circular hole, and wherein the housing includes a circular funnel that defines a sloped well region that is axially aligned with the central axis and directs the liquid from the nozzle to the aerosol generator. 5. A method as in claim 4, wherein the opening has an axis that is aligned with the central axis of the nozzle when the container is actuated, and wherein the slope of the well region is from 30 degrees to less than perpendicular relative to the axis of the opening. 6. A method as in claim 4, wherein the well region has a diameter of 10 mm to 15 mm, and wherein the opening has a diameter of at least 5 mm. 7. An aerosolization system, comprising: a container comprising a container body, the container being configured to deliver a unit dosage of a liquid when manually actuated a single time, the container further comprising a nozzle having a central longitudinal axis;an aerosolizer comprising: a housing defining a mouthpiece, the housing having a funnel that defines an opening configured to receive the unit dosage of liquid, the funnel having a flow axis;a cover movably attached to the housing so as to be movable between an open position where the opening is exposed and a closed position where the opening is covered;an aerosol generator disposed entirely within the housing, wherein the aerosol generator comprises a vibratable membrane having a front face, a rear face and a plurality of apertures that extend between the front face and the rear face, and a vibratable element used to vibrate the membrane, wherein the vibratable element is annular in geometry and surrounds the apertures, the vibratable element being planar along a lateral plane;wherein the opening is positioned to receive the unit dosage of the liquid from the container while the container is generally external to the housing so that the container can be grasped by a human hand to manually actuate the container the single time while the container is outside the housing, wherein the opening provides a direct liquid path to the rear face of the vibratable membrane where it is stored on the rear face until the vibratable element is energized to aerosolize the entire unit dosage of liquid stored on the rear face, and wherein the flow axis of the funnel is perpendicular to the lateral plane of the vibratable element so that when the nozzle is placed into the opening the central longitudinal axis is aligned with the flow axis and the dispersed liquid is directed perpendicularly onto the rear face from the nozzle. 8. An aerosolization system as in claim 7, wherein the single unit dosage has a concentration in the range from about 200 IU/ml to about 800 IU/ml. 9. An aerosolization system as in claim 7, wherein the container comprises a bottle containing a volume of the liquid, and wherein the bottle is configured to dispense a discrete droplet of the liquid of a certain volume when the bottle is squeezed. 10. An aerosolization system as in claim 7, wherein the opening comprises a circular hole, and wherein the liquid path is defined by a sloped well region formed by the housing. 11. An aerosolization system as in claim 10, wherein the opening has an axis, and wherein the slope of the well region is from 30 degrees to less than perpendicular relative to the axis of the opening. 12. An aerosolization system as in claim 10, wherein the well region has a diameter of about 10 mm to about 15 mm, and wherein the opening has a diameter of at least 5 mm. 13. An aerosolization system as in claim 7, wherein the container body has a proximal end, a distal end, and a nozzle positioned at the distal end, wherein the container further comprises a tip seal and a spring that biases the tip seal in a normally closed position, wherein the actuation of the container creates a sufficient pressure to move the tip seal and to deliver the unit dosage of the liquid from the nozzle, and wherein after dispensing, the tip seal closes to prevent the liquid from moving back into the container. 14. An aerosolization system, comprising: a housing defining a mouthpiece, the housing having an opening configured to receive a unit dosage of liquid that is dispensed from a container comprising a container body, the container being configured to deliver the unit dosage of a liquid when manually actuated a single time; a cover movably attached to the housing so as to be movable between an open position where the opening is exposed and a closed position where the opening is covered;an aerosol generator disposed entirely within the housing, wherein the aerosol generator comprises a vibratable membrane having a front face, a rear face, and a plurality of apertures that extend between the front face and the rear face, and a vibratable element used to vibrate the membrane, wherein the vibratable element is planar in geometry along a lateral plane and surrounds the apertures;wherein the opening in the housing comprises a sloped well region that has a flow axis and that provides a direct liquid path to the rear face of the vibratable membrane perpendicular to the lateral plane upon dispensing the unit dosage of the liquid into the opening, wherein the opening is adapted to receive the unit dosage of the liquid from the container while the container is generally external to the housing so that the container can be grasped by a human hand to manually actuate the container the single time while the container is outside the housing; and wherein the unit dosage of the liquid is stored on the rear face until the vibratable element is energized to aerosolize the entire unit dosage of liquid stored on the rear face. 15. An aerosolization system as in claim 14, wherein the container comprises a bottle containing of volume of the liquid, and wherein the bottle is configured to dispense a discrete droplet of the liquid of a certain volume when the bottle is actuated. 16.
