Bronchodilator effects of clemastine, ipratropium, bromide, and salbutamol in preschool children with asthma. 1981

R C Groggins, and A D Milner, and G M Stokes

The bronchodilator activity in nebulised salbutamol, ipratropium bromide, clemastine, and a placebo was studied in 14 asthmatic children aged between 3 and 5 years. Changes in lung function were monitored by measuring peak expiratory flow rate and total respiratory resistance using a modification of the forced oscillation technique. Ipratropium bromide produced a degree of bronchodilation similar to that of salbutamol, but the bronchodilatory activity of clemastine was not appreciably better than for the placebo.
