Ibuprofen has mildly hypertensive properties. - GreenMedInfo Summary

OBJECTIVES: Nonsteroidal anti-inflammatory drugs vary in their impact on blood pressure and the effect of lumiracoxib 100 mg once daily has not been studied previously. To examine whether lumiracoxib 100 mg once daily would result in lower 24-h mean systolic ambulatory blood pressure than ibuprofen 600 mg three times daily in osteoarthritis patients with controlled hypertension, a 4-week, randomized, double-blind, parallel-group study was conducted in 79 centres in nine countries. METHODS: Hypertensive osteoarthritis patients of 50 years at least whose office blood pressure was less than 140/90 mmHg on stable antihypertensive treatment were randomized to lumiracoxib (n = 394) 100 mg once daily or ibuprofen 600 mg three times daily (n = 393) and 24-h ambulatory blood pressure monitoring was performed at baseline and end of study. The primary outcome measure was a comparison of the change in 24-h mean systolic ambulatory blood pressure from baseline to week 4. Secondary analyses included other blood pressure-related endpoints and efficacy (pain) measurements. RESULTS: Compared with baseline, the 24-h mean systolic ambulatory blood pressure (least square mean) decreased in lumiracoxib-treated patients (-2.7 mmHg) and increased in ibuprofen-treated patients (+2.2 mmHg) at 4 weeks, estimated difference -5.0 mmHg (95% confidence interval -6.1 to -3.8) in favour of lumiracoxib. The 24-h mean diastolic ambulatory blood pressure changes were -1.5 mmHg (lumiracoxib), +0.5 mmHg (ibuprofen), difference -2.0 mmHg (95% confidence interval -2.7 to -1.3). Efficacy results were comparable. CONCLUSIONS: Treatment with lumiracoxib 100 mg once daily resulted in clinically significant lower blood pressure compared with ibuprofen 600 mg three times daily in osteoarthritis patients with well controlled hypertension.
