title: Asthmatic responses to inhaled aminophylline: a report of two cases.
abstract: We report two cases of occupational asthma induced by the inhalation of powdered aminophylline during the process of its manufacture. In both cases bronchial challenges were positive, producing delayed onset reversible airway obstruction. An immunologic mechanism appears to be operative in one case.
