Participants with hypertension who had been treated with MK-0954A (losartan potassium 50 mg + hydrochlorothiazide 12.5 mg) for at least three months
|Ages Eligible for Study:
||20 Years to 75 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
Data from 33 physicians from different levels of hospitals were invited to provide information on patients who received MK-0954A and had pre- and post-treatment serum uric acid and lipid profile reports during the study period. Each physician could provide up to 30 clinical charts of patients matching the inclusion criteria for the study.
- Had been treated with diuretic or angiotensin-receptor blockers (ARBs) 2 weeks before initiated treatment with MK-0954A 50/12.5 mg
- Serum creatinine >2 mg/dL
