Abstract
Disclosed is a small particle aerosol or nebulizer apparatus effective for providing small particles of aerosol containing drug; that is, particles having a maximum diameter of 10 microns but predominantly 1-2 microns, effective for treating the respiratory tract and lungs and providing respiratory retention of most drugs of at least 50 milligrams up to about 100 milligrams per hour. It has features which result in more efficient output of aerosol containing drugs, provides very small aerosol particles which are readily deposited in the lower respiratory tract and lungs, and provides even flow of drug containing aerosol to a patient when exhaling and inhaling.
