Brief Summary:
NSAIDs may increase blood pressure and blunt the effects of many antihypertensives. Members of these drug classes differ in their propensity to such an interaction.

Condition or disease Intervention/treatment Phase
Hypertension Drug: acetaminophen Drug: ibuprofen Drug: piroxicam Phase 4

Detailed Description:
To compare prospectively the effects of piroxicam, ibuprofen and acetaminophen on blood pressure control in hypertensive patients with osteoarthritis.
