It has been shown in nine asthmatic patients that practolol, a selective cardiac beta-adrenergic antagonist, successfully blocks the unwanted tachycardia and palpitation following isoprenaline inhalation without hindering the beneficial bronchodilator action of the drug. Practolol is a useful adjunct to bronchodilator therapy in the management of bronchial asthma.
