Abstract:
:The hydrochlorothiazide component of Maxzide (Lederle Laboratories, Pearl River, NY) has been shown to be more bioavailable than the hydrochlorothiazide component of Dyazide (Smith, Kline and French Laboratories, Philadelphia, PA). The authors compared the antihypertensive effectiveness of a half-tablet of Maxzide (25 mg of hydrochlorothiazide and 37.5 mg of triamterene) to one capsule of Dyazide (25 mg of hydrochlorothiazide and 50 mg of triamterene) to determine if the difference in bioavailability would be reflected in differences in blood pressure control and metabolic changes. Thirty patients were studied in a randomized open-label crossover design study. There was a significant reduction in systolic blood pressure for both treatments although there was no difference in blood pressures at any time during the study between the two agents. There were no statistically significant differences between Maxzide and Dyazide in terms of metabolic changes for potassium, magnesium, glucose, cholesterol, triglycerides, uric acid, or calcium. Although the hydrochlorothiazide component of Maxzide is more bioavailable than that of Dyazide this did not translate into enhanced hypotensive efficacy.
