The acute effects of the administration of rimiterol aerosol in asthmatic children.

1 Ten asthmatic children received on two separate occasions rimiterol (500 microgram) and orciprenaline (1.5 mg) as aerosols in a double-blind, crossover design trial. Respiratory parameters (FEV1, FVC and PEFR) and pulse rate were recorded for 60 min after each administration. 2 Rimiterol produced effective bronchodilation in children with negligible cardiac stimulation. It differed from orciprenaline in that the peak bronchodilator effect was not maintained during the 60 min observation period. 3 Rimiterol is a selective, short-acting, sympathomimetic bronchodilator in children.
