Antihypertensive treatment with metoprolol or hydrochlorothiazide in patients aged 60 to 75 years. Report from a double-blind international multicenter study.

In a randomized double-blind study (N = 562), a traditional treatment schedule, starting antihypertensive treatment in elderly hypertensive patients (60 to 75 years old) with 25 mg of hydrochlorothiazide once daily and doubling the dose if a satisfactory response was not achieved, was compared with antihypertensive treatment of 100 mg of metoprolol once daily, adding 12.5 mg of hydrochlorothiazide for patients whose response was not satisfactorialy achieved with metoprolol alone. Systolic and diastolic blood pressure was significantly reduced with both regimens. The frequency rates of responders (diastolic blood pressure, less than or equal to 95 mm Hg) in the metoprolol group and the hydrochlorothiazide group were 50% and 47% after four weeks and 65% and 61% after eight weeks, respectively. There were no significant differences in total symptom score or single symptoms between the regimens, but significantly more patients had hypokalemia and hyperuricemia with the hydrochlorothiazide regimen. Thus, we conclude that beginning antihypertensive treatment with 100 mg of metoprolol once daily and adding a small dose of hydrochlorothiazide (12.5 mg) in patients whose response is not satisfactory with metoprolol alone appears to be effective and safe in elderly hypertensive patients.[1]
