[Effect of adrenergic beta receptor blockaders on bronchial patency in ischemic heart disease].

The effect of beta-adrenergic blocking agents inderal, trazicor, visken, benzoral and aptin on the bronchial patency was studied by means of four ventilation indices in 85 patients, 62 of whome had various diseases of the lungs; 44 of these patients had bronchial obstruction. It was established that all beta-blocking agents are detrimental to bronchial patency in patients with concomitant bronchial obstruction. In exacerbation of bronchial asthma, beta-blocking agents are contraindictaed. When it is necessary to prescribe beta-blocking agents for other patients with concomitant bronchial obstruction visken is the drug of choice. It should be given per os, with preliminary control of the function of external respiration.
