When the dry powder type inhalation steroid (DPI-ICS) device is selected, its suitability based on the inspiratory flow rate value is not checked for all patients. It was therefore considered necessary to establish standards for selecting inhalation devices. With this in mind, the relationship between the inspiratory flow rate and the device was investigated, and the application of this to the selection of inhalation devices was studied. The subjects for this study were outpatients of the Mie Chuo Medical Center who were using DPI-ICS devices. The inspiratory flow rate was measured using an Incheck instrument and the suitability of devices was examined with an inhalation tester. Though 13.5% of the subjects using Diskus and 25% of those using Turbuhaler satisfied the mimimum requirement of 30 L/min, there was no reaction with the inhalation tester which suggested that inhalation might not be very good. How-ever, inhalation was more effective when patients were given proper instruction on inhalation. Changing devices based on investigation of their suitability was also found to be effective. In view of the above findings, we felt it necessary to develop a system for the prescribing of inhalers by doctors after pharmacists have investigated their suitability using the Incheck instrument and the inhalation tester. We have been trying out such a system.
