In an open study with 16 angina pectoris patients with concomitant chronic obstructive bronchitis, the effect of single oral doses of the beta-adrenoceptor antagonist bisoprolol (5, 10, 15, 20, 30, and 40 mg) on blood pressure (BP), heart rate (HR), airway resistance (AWR), and forced expiratory volume in 1 s (FEV1) was investigated. In the dose range between 5 and 20 mg, no increase in AWR and no decrease in FEV1 was observed. Thirty and 40 mg of bisoprolol produced an increase in AWR and a decrease in FEV1. A reduction in BP and HR was observed even after the lowest bisoprolol dose.
