Inhalation Devices: Various forms of administration for Therapeutic Optimization

Abstract

Introduction: Aerosol therapy consists of spraying liquid particles suspended for therapeutic purposes in the respiratory tract. With direct absorption and deposition at the lung level, avoiding side effects and presenting fast response time. Several factors infl uence the drug action, such as size, particle movement, ventilatory fl ow, pulmonary expansion, anatomy, respiratory mechanics and the nebulizer and patient interface. The therapeutic optimization depends on the type of nebulizer differentiating itself by the physical principle that generates the mist.
