Inhalation Toxicology
Utilizing the respiratory route of delivery gets more drug to the site of disease than parenteral administration while limiting potential systemic side effects. Alternatively, systemic delivery of drugs through the respiratory tract has been shown to effectively control metabolic disease (e.g., diabetes), to provide needle-free delivery for drugs and vaccines, to avoid “first pass” liver metabolism, and to provide a faster onset of action (e.g., naloxone) than parenteral delivery. To support respiratory drug development and inhalation toxicology, multiple clinical and nonclinical liquid (nebulizer, nasal spray), dry powder, and metered dose inhaler (MDI) aerosol generators are used to produce atmospheres of drug that are delivered to nonclinical species through unique aerosol delivery systems
