摘要：
A pressurized metered dose inhaler having an actuator constructed and arranged so as to inhibit airflow due to patient inhalation in the vicinity of the orifice of the nozzle block when the valve stem is in its dispensing position. This design reduces unwanted oropharyngeal deposition of medicament and increases the relative amount of medicament to the lung.
