Effects of celiprolol on the bronchial reactivity in asthma

In 10 patients with bronchial asthma but normal ventilatory function, celiprolol, a cardioselective beta-adrenoreceptor antagonist, did not significantly affect forced expiratory volume in 1 second (FEV1) or airways resistance (Raw). In contrast, metoprolol substantially reduced FEV1 and increased Raw. In addition, compared with metoprolol, celiprolol induced a greater recovery of FEV1 and Raw after methacholine-induced bronchoconstriction.
