Abstract

Twenty-four patients with bronchial hyperreactivity due to asthma (8 patients), COPD (13) and of unknown origin (3) entered and completed a randomized double-blind intraindividual cross-over study. Thirteen patients first received the highly selective vasodilatating beta 1-blocker Nebivolol (5 mg) and 11 patients first placebo with a wash-out period of at least 2 days. Before the controlled oral intake of the tablets, the patients were challenged with increasing inhalative doses of carbachol between 8 and 9 a.m. according to the recommendation of the German Society of Pneumology. At 10, 11 and 12 a.m. and 1 and 2 p.m. control measurements of airway patency (Raw, FEV1) were performed in the body box. At the same time intervals, oxygen saturation and pulse rate (pulsoximetry) including systolic and diastolic blood pressure were monitored. From 2-3 p.m. the carbachol provocation was repeated as in the morning to assess the changes in hyperreactivity due to Nebivolol.

RESULTS:

During the Nebivolol phase, blood pressure values and pulse rates were significantly reduced compared to the placebo phase. At the same time intervals, no significant changes of the measured body box variables to assess airway obstruction were observed during therapy with Nebivolol compared to placebo. Comparing the measured variables (maximal deviation from base-line values of Raw and FEV1) during carbachol provocation in the afternoon under Nebivolol and placebo with the values in the morning before any medication (base-line values), there were also no significant detectable differences indicating an increase of bronchial hyperreactivity under Nebivolol treatment.

CONCLUSION:

It seems that Nebivolol in these hyperreactive patients is as safe as placebo despite its significant effect on blood pressure and pulse rate.
