BACKGROUND: Nonsteroidal antiinflammatory drugs (NSAIDs) may alter blood pressure through their inhibitory effects on prostaglandin biosynthesis. Such potential hypertensive effects of NSAIDs have not been adequately examined in the elderly, who are the largest group of NSAID users. METHODS: We performed a randomized, double-blind, two-period crossover trial of ibuprofen (1800 mg per day) vs placebo treatment in patients older than 60 years of age with hypertension controlled with hydrochlorothiazide. While continuing their usual thiazide dosage, subjects were randomized to a 4-week treatment period (ibuprofen or placebo) followed by a 2-week placebo wash-out period and a second 4-week treatment period with the alternative therapy. Supine and standing systolic and diastolic blood pressures were measured weekly. RESULTS: Of 25 randomized subjects, 22 completed the study protocol (mean age = 73 +/- 6.7 years). Supine systolic blood pressure and standing systolic blood pressure were increased significantly with ibuprofen treatment, compared with placebo. Mean supine systolic blood pressures were 143.8 +/- 21.0 and 139.6 +/- 15.9 mmHg on ibuprofen and placebo, respectively (p = .004). Mean standing systolic blood pressures were 148.1 +/- 19.9 and 143.4 +/- 17.9 mmHg on ibuprofen and placebo, respectively (p = .002). CONCLUSION: We conclude that 1800 mg per day of ibuprofen does induce a significant increase in systolic blood pressure in older hypertensive patients treated with hydrochlorothiazide. NSAID therapy may negatively impact the control of hypertension in elderly patients.
