Abstract:
This article describes the immediate effect of verapamil, a calcium antagonist, on pulmonary functions in bronchial asthma. The effect of oral administration of 80 mg of verapamil or placebo was studied in a randomized double-blind manner in 30 extrinsic asthmatic subjects. No significant bronchodilator effect was observed with verapamil administration. There were no significant changes in heart rate and blood pressure after verapamil.
