A method of treating a patient with a pulmonary disease, where the method includes delivering a dose of aerosolized medicament intermittently to a ventilator circuit coupled to the respiratory system of the patient. Also, a method of treating a patient with a pulmonary disease, where the method includes taking the patient off a ventilator, and administering to the patient, a nebulized aerosol comprising from about 100 μg to about 500 mg of a medicament. Also a method of treating a patient with a pulmonary disease, the method comprising administering an aerosolized first medicament comprising amikacin to the patient and administering, systemically a second medicament comprising an antibiotic to the patient that also treats the pulmonary disease, wherein a resulting amikacin concentration in the lung and/or pulmonary system is therapeutically-effective, and an amount of the systemically administered antibiotics is reduced.

1. A nebulizer system comprising: a housing which defines a passageway that is adapted to deliver an aerosolized liquid comprising a medicament to a user;a vibrating mesh aerosol generator positioned to provide an aerosolized liquid into the passageway;a controller having a memory storing a plurality of aerosol generator operation programs, wherein the controller is in electrical communication with the aerosol generator, and wherein each operation program controls the operation of the aerosol generator according to a respective mode, and wherein the controller selects from among the plurality of operation programs to select a mode of operation based at least in part on the identity of the medicament and based in part on information received in a signal from a ventilator; andwherein the controller is configured to operate the aerosol generator to deliver the medicament to a patient by inhalation. 2. The nebulizer system of claim 1 wherein the medicament comprises an antibiotic. 3. A system for administering aerosolized medicament, comprising a vibrating mesh nebulizer preloaded with about 100 micrograms to about 500 milligrams of a medicament and comprising an aerosol generator;a controller having a memory and a plurality of aerosol generator operation programs, wherein the controller is operatively coupled to the nebulizer, wherein each operation program controls the operation of the aerosol generator according to a respective mode, and wherein the controller selects from among the plurality of operation programs to select a mode of operation based at least in part on the identity of the medicament;a housing which defines a passageway that is adapted to receive said aerosolized medicament and deliver said aerosolized medicament to a patient; andwherein the system is configurable to administer aerosolized medicament to a patient both on-ventilator and off-ventilator, and when administering aerosolized medicament to a patient on-ventilator, the controller selects from among the plurality of operation programs to select a mode of operation based in part on information received in a signal from the ventilator. 4. An apparatus for aerosolizing a liquid, comprising a vibrating mesh nebulizer and a controller, wherein the controller stores a plurality of operation programs, each operation program controlling the nebulizer to operate in a respective mode, and wherein the modes include a continuous aerosolization mode wherein aerosolized medicament is generated a constant rate throughout the breathing cycle, a first phasic mode wherein an aerosolized medicament is administered for substantially all of the inhalation phase of the breathing cycle, and a second phasic mode wherein the aerosolized medicament is administered during a predetermined portion of the inhalation phase, and combinations thereof, and wherein the controller selects from among the plurality of operation programs to select a mode in which to operate based at least in part on the identity of the medicament and based in part on information received in a signal from a ventilator. 5. The apparatus of claim 4 wherein said first phasic delivery mode provides a delivery efficiency of at least about 15% by weight of the total amount of medicament that is aerosolized. 6. The apparatus of claim 4 wherein said second phasic delivery mode provides a delivery efficiency of at least 60% by weight of the total amount of medicament that is aerosolized. 7. The apparatus of claim 6 wherein in said second phasic mode, aerosolized medicament is administered during a predetermined portion of the inhalation phase beginning at the onset of inhalation. 8. An apparatus for delivering an aerosolized medicament to a patient, the apparatus comprising: a nebulizer means having a piezoelectrically-actuated vibrating mesh aerosol generator;a controller means having a memory and a plurality of aerosol generator operation programs, wherein the controller is operatively coupled to the nebulizer means, wherein each operation program controls the operation of the aerosol generator according to a respective mode, and wherein the controller selects among the plurality of operation programs to select a mode of operation based at least in part on the identity of the medicament and in part on information received in a signal from a ventilator;a sensing means for measuring at least one breathing characteristic of a patient; anda processor means for processing said characteristic and using the measurements of the at least one breathing characteristic of the patient from the sensing means to control the operation of the aerosol generator in at least one of the modes to deliver an aerosolized medicament over a predetermined portion of an inhalation phase, wherein a percentage of increase in efficiency in delivery for such predetermined portion of said inhalation phase over delivery during an entire inhalation phase is itself greater than an increase in efficiency of delivery during said inhalation phase compared to aphasic administration of the aerosol. 9. The apparatus of claim 8 wherein the breathing characteristic is selected from a breathing pattern, a peak inspiratory flow rate, a breathing rate, an exhalation parameter, a breathing regularity, a tidal volume, and combinations thereof. 10. An apparatus for enhancing delivery efficiency of a pharmaceutical agent, the apparatus comprising a vibrating mesh nebulizer, and an electronic controller coupled to the nebulizer, the electronic controller further comprising a plurality of operation programs and a sensor, wherein the controller selects one of the plurality of operation programs based on the identity of said pharmaceutical agent, and aerosolizes said pharmaceutical agent based in part upon information from said sensor and in part on information received in a signal from a ventilator. 11. The apparatus of claim 10 wherein said aerosolized pharmaceutical agent is delivered near the beginning of a patient's breathing cycle. 12. The apparatus of claim 10 wherein said aerosolized pharmaceutical agent is delivered near the end of a patient's breathing cycle.
