Nebulised sodium cromoglycate and verapamil in methacholine induced asthma.
Fifteen children with asthma underwent challenges with methacholine on separate days after double blind administration by nebuliser of either verapamil (5 mg), cromoglycate (20 mg), or saline (placebo). The provocation doses that produced a 20% fall in forced expiratory volume in one second (PD20) were analysed. There was variation in the protective effects of verapamil and cromoglycate among t...
متن کاملSodium cromoglycate and ipratropium bromide in exercise-induced asthma.
In thirteen patients with extrinsic asthma the effects of placebo, sodium cromoglycate, ipratropium bromide, and ipratropium bromide plus sodium cromoglycate were studied in a random double-blind fashion to assess their inhibitory action in exercise-induced asthma (EIA). Exercise testing consisted of steady state running on an inclined treadmill for up to eight minutes. In eight of the 13 patie...
متن کاملDose-response study of sodium cromoglycate in exercise-induced asthma.
Ten patients with exercise-induced asthma participated in a single-blind dose-response study comparing the protective effect of inhaled sodium cromoglycate in increasing concentrations from 2 to 40 mg/ml. Saline was used as a control. Effects were assessed from the mean maximal percentage fall in forced expiratory volume in one second (FEV1) after the patients had run on a treadmill for eight m...
متن کاملEffect of verapamil and sodium cromoglycate on leukotriene D4 induced bronchoconstriction in patients with asthma.
Leukotriene D4 (LTD4) may be an important mediator in asthma. The effect of verapamil and sodium cromoglycate on LTD4 induced bronchoconstriction has been examined in seven patients with asthma. The bronchoconstrictor response to increasing concentrations of inhaled LTD4 (0.0032-50 micrograms/ml) was assessed by measuring changes in FEV1, specific airways conductance, and flow rate at 30% of vi...
متن کاملAttenuation of exercise induced asthma by nedocromil sodium and sodium cromoglycate.
A randomized double blind cross over trial to compare nedocromil sodium and sodium cromoglycate with placebo in the prevention of exercise induced asthma was conducted. Twenty asthmatics received nedocromil sodium, sodium cromoglycate or placebo via metered dose inhalers on successive days 30 minutes before exercise in a randomized order. Nedocromil sodium and sodium cromoglycate gave sufficien...
