Abstract
The present invention is directed to devices, systems, and methods for monitoring inhaled drug usage to predict when an acute attack or exacerbation of a disease, such as a respiratory disease, is imminent. Instrumented inhalers that use modular designs with standard components are disclosed, as are systems for monitoring the instrumented inhalers. Also disclosed are methods for determining whether or not a patient's inhaled drug usage pattern indicates that an acute attack or disease exacerbation is imminent, and notifying appropriate medical personnel of any usage patterns indicative of an attack or disease exacerbation. If such an attack or exacerbation is imminent, additional therapeutic agents may be dispensed to the patient or other interventions made.
