Do Beta Blockers Cause Bronchospasm?

β-blocker induced bronchospasm can develop in non-asthmatic patients even with cardio-selective agents such as celiprolol. The onset of adverse effects from β-blockers is not necessarily temporally related to the initiation of treatment.

Which beta blockers do not cause bronchospasm?

Cardioselective ß blockers such as atenolol and metoprolol are at least 20 times more potent at blocking ß-1 receptors than ß-2 receptors. At therapeutic doses the ß-2 blocking effect, and therefore the risk of bronchoconstriction, is negligible.

Are beta blockers bronchoconstriction?

Introduction Beta-blockers are key in the management of cardiovascular diseases but blocking airway β₂-receptors can cause severe and sometimes fatal bronchoconstriction in people with asthma.
