ABSTRACT:
A nebulizer device, comprising: (a) a housing defining an interior volume therewithin, including a reservoir portion for holding medicament therein for entrainment into a carrier gas to form a delivery gas mixture comprising nebulized medicament and carrier gas; (b) a discharge port connected to the housing in flow communication with the interior volume therewithin, for discharging the delivery gas mixture from the housing; (c) a jet passage member having (i) an inlet portion for introduction of carrier gas thereinto and (ii) a nozzle portion positioned in the interior volume of the housing for discharging carrier gas in jet form in the interior volume, for entrainment of medicament from the reservoir portion of the housing in the carrier gas jet, such nozzle portion comprising a nozzle orifice accommodating carrier gas flow therethrough, wherein the nozzle orifice has an equivalent orifice diameter in the range of from about 0.005 inch to about 0.020 inch.
