Abstract: A nebulizer comprising an aerosol generator and a titration mechanism comprising a dosing mechanism, a screw assembly, a plunger and an actuator, wherein the dosing mechanism is rotatably mounted in the nebulizer and the plunger is mounted in the nebulizer to travel along a longitudinal axis substantially perpendicular to the plane of rotation of the dosing mechanism. The actuator is mounted to the nebulizer to travel in the direction of the longitudinal axis. The screw mechanism allows the rotation of the dosing mechanism to fix a variable distance of travel of the plunger based on the selected dose, without moving the plunger longitudinally. This allows the user to verify and if necessary correct the selected dose prior to any drug being released from the vial. Operation of the actuator causes longitudinal movement, through the screw mechanism, to the plunger.

Abstract: A transdermal drug delivery system with microprojections for disrupting a body surface to an individual. At least some of the microprojections arise from a first microprojection layer and at least some of the microprojections arise from a second microprojection layer. The first and second microprojection layers are stacked together.

Abstract: A transdermal drug delivery system with microprojections for disrupting a body surface to an individual. At least some of the microprojections form groups in a microprojection array. There are repeated units of such groups in the microprojection array.

Abstract: A transdermal drug delivery system with microprojections for disrupting a body surface to an individual. At least some of the microprojections have a depression for increasing drug loading by a drug coating.

Abstract: Devices and methods for nebulizing a fluid are described. A replaceable fluid assembly may include a reservoir and a fluid cartridge. The reservoir may be detachable from the fluid cartridge and may be assembled by the prior prior to loading into the nebulizing device.
