Interaction Between Antihypertensives and Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) - Full Text View

Purpose

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.

Arms	Assigned Interventions
No Intervention: 1 Hypertensive persons taking either lisinopril/hydrochlorothiazide fixed combination or amlodipine all the time.
Experimental: 2 Intervention: NSAID. Hypertensives with osteoarthritis taking already amlodipine (5-10 mg o.d. per os) were randomized to the following drug interventions: to take either acetaminophen (1000 mg t.i.d. per os), piroxicam (10-20 mg o.d. per os) or ibuprofen (400-600 mg t.i.d. per os) for 1 month	Drug: acetaminophen acetaminophen 1000 mg t.i.d. per os ibuprofen 400-600 mg t.i.d. per os piroxicam 10-20 mg o.d. per os Other Name: paracetamol Drug: ibuprofen acetaminophen 1000 mg t.i.d. per os ibuprofen 400-600 mg t.i.d. per os piroxicam 10-20 mg o.d. per os Drug: piroxicam acetaminophen 1000 mg t.i.d. per os ibuprofen 400-600 mg t.i.d. per os piroxicam 10-20 mg o.d. per os
Experimental: 3 Hypertensives with osteoarthritis taking already lisinopril/hydrochlorothiazide (20/12.5 mg o.d. per os), were sequentially randomized to the following drug interventions: acetaminophen (1000 mg t.i.d.), ibuprofen (400-600 mg t.i.d.) or piroxicam (10-20 mg o.d.), for 1 month each	Drug: acetaminophen acetaminophen 1000 mg t.i.d. per os ibuprofen 400-600 mg t.i.d. per os piroxicam 10-20 mg o.d. per os Other Name: paracetamol Drug: ibuprofen acetaminophen 1000 mg t.i.d. per os ibuprofen 400-600 mg t.i.d. per os piroxicam 10-20 mg o.d. per os Drug: piroxicam acetaminophen 1000 mg t.i.d. per os ibuprofen 400-600 mg t.i.d. per os piroxicam 10-20 mg o.d. per os

Detailed Description:

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