Summary

NSAIDs such as fenbufen can reduce the antihypertensive effect of beta-blockers by inhibiting prostaglandin synthesis and causing sodium and fluid retention. The effect is more evident with prolonged use.

What this interaction means in plain words

Betaxolol and Fenbufen 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.

Evidence level: Moderate

Why it happens

NSAID inhibition of vasodilatory prostaglandins and renal sodium retention antagonizes beta-blocker blood pressure lowering.
