Claims
- 1. A device for delivering drug containing aerosols for inhalation therapy including:
a housing; and, an airway including a gas/vapor mixing area, wherein the airway includes a subassembly, and wherein the subassembly includes a metallic substrate, and wherein a composition comprising a drug is coated on the substrate.
- 2. The device according to claim 1, wherein the device further includes a heater system.
- 3. The device according to claim 1, wherein the airway contains a restricted cross-sectional area along the gas/vapor mixing area.
- 4. The device according to claim 1, wherein the metallic substrate comprises stainless steel.
- 5. The device according to claim 2, wherein the heater system is an inductive heater system.
- 6. The device according to claim 3, wherein the airway includes means for causing turbulence as air moves through the airway.
- 7. The device according to claim 5, wherein the inductive heater system includes a ferrite toroid.
- 8. The device according to claim 6, wherein the device further includes an inductive heater system.
- 9. The device according to claim 8, wherein the drug in the composition is an antiparkinsonian drug.
- 10. The device according to claim 8, wherein the drug in the composition is an opioid.
- 11. The device according to claim 8, wherein the drug in the composition is an anxiolytic.
- 12. A method of forming a drug containing aerosol for use in inhalation therapy comprising:
(a) heating a substrate coated with a composition comprising a drug to form a vapor; and, (b) mixing the vapor with a volume of air such that an aerosol having particles is formed, wherein the MMAD of the particles is stable for at least 1 s.
- 13. The method according to claim 12, wherein the substrate is heated by moving it through a heating zone.
- 14. The method according to claim 12, wherein an aerosol having about 109 particles/cc of air is formed.
- 15. The method according to claim 13, wherein the heating zone is primarily produced by eddy currents induced by an alternating magnetic field.
- 16. The method according to claim 15, wherein the drug in the composition is an antiparkinsonian drug.
- 17. The method according to claim 15, wherein the drug in the composition is an opioid.
- 18. The method according to claim 15, wherein the drug in the composition is an anxiolytic.
