Abstract

Inhaled corticosteroid (ICS) will be effective if used properly. Inadequate intake may result in insufficiency, such as for elderly asthmatics, in particular, for use of dry powder inhalers. 312 asthmatics treated with ICS for at least 6 months in the 6 facilities belonging to the Chugoku Shikoku Adult Asthma Research Forum were subject to investigation of the peak inspiratory flow (PIF) measured using In-check® and related factors. Nine (2.8%) patients were considered to have insufficient intake. By multivariate analysis, PIF (L/min) prediction formula was as follows: 79.0+0.19* peak expiratory flow (PEF: L/min)+22.9* FVC (L)-0.68* onset age (years)+34.7* gender (male, 1; female, 0)+16.1* V50/V25, [r^2=0.677, p
