1. Bronchodilatation was produced in eight normal subjects by inhalation, on separate occasions, of the atropine-like drug ipratropium bromide (0.16 mg by pressurized inhaler; 1 mg nebulized) and the beta 2-sympathomimetic salbutamol (0.8 mg by pressurized inhaler; 5 mg nebulized). 2. Mean specific airways conductance (sGaw) increased from a mean value of 0.185 +/- SE 0.002 to 0.292 +/- 0.023 s...
The effect of the inspiratory flow rate during deep inspiration on the regulation of bronchomotor tone was studied in nine normal and 22 asthmatic subjects. Changes in bronchial tone were assessed by respiratory resistance measured by an oscillation method. In normal subjects with bronchoconstriction induced by methacholine a rapid deep inspiration reduced respiratory resistance more than a slo...
Salbutamol solution is usually administered by nebuliser in a dose of 5 mg. Little evidence exists that this is the optimal dose for bronchodilatation or that this dose is without side-effects. Twelve patients with asthma were given increasing doses of salbutamol 1.5 mg, 3.0 mg, 7.5 mg, and placebo. Treatments were administered twice daily for four days in a double-blind manner. Measurements of...
