An aerosolization system, comprising: a dispenser (30, 80) comprising an elongate dispenser body having a longitudinal axis extending between a proximal end and a tip (36, 82) at a distal end through which a liquid medicament is dispensed, wherein the dispenser (30, 80) further comprises a container having the liquid medicament and a dispensing mechanism that operates to dispense a metered quantity of the liquid medicament from the tip (36, 82) each time the dispenser body is compressed; an aerosolization device comprising an aerosolization device housing (12, 112) having a mouthpiece, a vibratable member within the aerosolization device housing (12, 112) and disposed to eject liquid droplets through the mouthpiece, a reservoir (22, 122) to hold the liquid medicament until aerosolized by the vibratable member, and an opening (20, 120) in a top surface of the aerosolization device housing (12, 112) that is in fluid communication with the reservoir (22, 122), wherein the dispenser (30, 80) is separate from the aerosolization device housing (12, 112); wherein the tip (36, 82) of the dispenser (30, 80) comprises multiple alignment features that are configured to assist to properly align and position the tip (36, 82) within the opening (20, 120), wherein the alignment features are configured to serve as stops to limit insertion of the tip (36, 82) into the opening and to provide a tactile feel to let a user know when the tip (36, 82) has been properly inserted; wherein the opening (20, 120) is engageable with the tip (36, 82) such that the dispenser body is generally perpendicular to the top surface of the aerosolization device housing and is seated within the opening (20, 120) such that the dispenser body is self-standing outside of the aerosolization device housing; and wherein the opening (20, 120) defines an interface that engages with the tip (36, 82) such that when the tip (36, 82) is inserted into the opening (20, 120), the interface stabilizes the dispenser (30, 80) in an upright orientation outside of the aerosolization device housing (12, 112) to permit the dispenser (30, 80) to be grasped with one hand such that the fingers wrap around the dispenser body, with the thumb closest to the proximal end and the last finger closest to the tip (36, 82), and while grasping the dispenser (30, 80), forcing the elongate dispenser body toward the tip (36, 82) to cause the dispenser body to compress, thereby operating the dispensing mechanism and causing the metered quantity of the liquid medicament to eject into the reservoir (22,122) each time the dispenser body is compressed. a dispenser (30, 80) comprising an elongate dispenser body having a longitudinal axis extending between a proximal end and a tip (36, 82) at a distal end through which a liquid medicament is dispensed, wherein the dispenser (30, 80) further comprises a container having the liquid medicament and a dispensing mechanism that operates to dispense a metered quantity of the liquid medicament from the tip (36, 82) each time the dispenser body is compressed;
