Summary
Bisoprolol can oppose the bronchodilating action of formoterol and may worsen bronchospasm in patients with asthma or COPD. Its high beta-1 selectivity makes this less likely than with nonselective agents, particularly at low doses.
What this interaction means in plain words
Bisoprolol and Formoterol-mometasone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Bisoprolol belongs to Cardiovascular; Formoterol-mometasone belongs to Respiratory.
Why it happens
Competitive pharmacodynamic antagonism at beta-adrenergic receptors.
What to do
Start bisoprolol at a low dose and monitor respiratory symptoms and lung function. Reassess the need for the beta-blocker if bronchospasm or reduced formoterol response occurs.
