Summary
Beta-blockers antagonize beta-agonist bronchodilators, so metaproterenol may work less well and bronchospasm may occur in susceptible patients. Cardioselectivity of betaxolol lowers but does not remove this risk.
What this interaction means in plain words
Betaxolol and Metaproterenol 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.
Why it happens
Pharmacodynamic antagonism at beta-adrenergic receptors.
What to do
Monitor respiratory symptoms and bronchodilator response. Avoid the combination in asthma where possible, or use the lowest betaxolol dose.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
