Effects of celiprolol, a cardioselective beta-blocker, on respiratory function in asthmatic patients.
The aim of this study was to compare the pulmonary effects of a single dose of celiprolol 400 mg, versus bisoprolol 20 mg and the combination of celiprolol 400 mg plus propranolol 40 mg versus placebo plus propranolol 40 mg. We conducted a double-blind randomized cross-over study in 10 stable asthmatic patients (mean age +/- SD 31 +/- 7 yrs) with forced expiratory volume in one second (FEV1): 2.5 +/- 0.7 l. A three-day washout period preceded each treatment period. Measurements of respiratory function were done before treatment and after 90, 120 and 180 min. There was a significant increase of FEV1 (+12%) and forced vital capacity (FVC) (+8%) after celiprolol (p less than 0.05) and a decrease of FEV1 (-9%) after propranolol. Concerning the combination, celiprolol inhibits the bronchoconstrictor effects of propranolol. We conclude that celiprolol has bronchosparing properties in asthmatic patients, and even improves some of the ventilatory parameters.
