Effect of ketotifen on the bronchodilation induced by salbutamol.
1988
Twelve subjects with stable asthma each inhaled two puffs (200 micrograms) of salbutamol on 2 separate days 3 h after double-blind oral administration of ketotifen (two 1-mg capsules) or identical placebo. FEV1 was recorded before and at intervals for 4 h after inhalation of salbutamol. Overall, the FEV1 was significantly greater during the 4-hour period after premedication with ketotifen (p less than 0.02) and the difference between the effect of placebo and ketotifen was statistically significant at 120, 180 and 240 min after salbutamol (p less than 0.05).
Dose-Related Effect of Beclomethasone Dipropionate on Airway Responsiveness in Asthma
1990
The effects of twice daily inhaled beclomethasone dipropionate (BDP) at two dose levels (500 and 1,000 micrograms daily) on the airway responsiveness to inhaled histamine was evaluated by a randomized, single-blind, cross-over study in 10 patients with stable asthma. The 12-week study began with a 3-week run-in period of baseline treatment, which was continued unchanged throughout the study, and the two treatment periods were separated by a 3-week placebo period. Patients attended the laboratory every 3 weeks for spirometry and histamine inhalation tests to determine the provocative concentration of histamine causing a 20% fall in forced expiratory volume in 1 s (PC20 of FEV1). There was a …
