Summary
NSAIDs can reduce the antihypertensive effect of beta-blockers, and may cause fluid retention. Blood pressure control can worsen with prolonged use.
What this interaction means in plain words
Penbutolol and Piroxicam 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
NSAID inhibition of vasodilatory renal and vascular prostaglandins causes sodium retention and blunts the blood pressure lowering effect.
What to do
Monitor blood pressure when starting or stopping the NSAID and adjust antihypertensive therapy as needed. Use the shortest NSAID course.
