[A new inhalation system for bronchodilatation. Study of the acceptance of the Ingelheim M inhaler in chronic obstructive respiratory tract diseases]

Abstract

The aim of this study was to investigate the acceptance and convenience of a new inhalation system for the treatment of chronic obstructive pulmonary disease. The Ingelheim M inhalator, an inhalation system with a supply magazine for six powder-filled capsules represents a further development of the Ingelheim inhalator in which only a single capsule can be utilized. The study was designed as an open, randomized, crossover trial involving 60 ambulatory adult patients. Each treatment period lasted two weeks. The medication tested was Berodual Inhaletten. The success of treatment was checked on the basis of peak flow metering each morning prior to and after initial inhalation. The results of the study show a highly significant preference on the part of the patients for the new inhalation system. The advantage most emphasized by the patients was the fact that they were able to carry with them their entire daily dose. Differences in the symptomatology of chronic obstructive pulmonary disease were not observed with these inhalation systems.
