摘要： Inhaler systems and method of use thereof are disclosed. One exemplary inhaler system, among others, includes an inhalation/exhalation structure including an inhalation/exhalation orifice. In addition, the inhaler system includes a medicament supply system having a medicament ejector disposed adjacent the inhalation/exhalation orifice. The medicament supply system controllably ejects medicament droplets from the medicament ejector. Further, the inhaler system includes a flow control system in fluidic communication with the medicament ejector. The flow control system is configured to entrain the medicament droplets and pass the medicament droplets to the inhalation/exhalation orifice when the patient applies an in-breath to the inhalation/exhalation structure. In addition, the flow control system is configured to impede a flow of air from the inhalation/exhalation orifice to the medicament ejector when the patient applies an out-breath into the inhalation/exhalation structure.
