Summary of "Effects of a Fixed Combination of Losartan With Hydrochlorothiazide on Glucose Tolerance in Hypertensive Patients Uncontrolled with Angiotensin II Receptor Blockers Alone."

Aim: The concomitant use of angiotensin II receptor blocker (ARB) with low doses of hydrochlorothiazide (HCTZ) may provide additional antihypertensive activity. HCTZ induces hypokalemia and hyperglycemia, while ARB slightly induces hyperkalemia. Recently, it has been reported that ARB/ HCTZ did not worsen fasting blood sugar levels; however, the detailed glucose tolerance change effect with combination therapy of ARB/HCTZ compared to ARB alone therapy remains to be investigated.Methods: Treated non-diabetes mellitus (DM) hypertensive patients taking a common dose of ARB regimens, not achieving blood pressure (BP) goals, were switched to 50 mg Losartan/12.5 mg HCTZ combinations, and the 75 g oral glucose tolerance test (75 g OGTT) was performed before switching and after switching at 3 months.Results: This study included 30 patients aged 66.5±8.7 years, 67% women. Pre-switching BP 146.6±17.0/ 88.4±10.4 mmHg decreased and was maintained at a steady state, reaching 131.4±1.0/73.8±8.8 mmHg (p<0.001) 3 months later. After switching, blood glucose levels on the 75 g OGTT at fasting, 30, 60 and 120 minutes were significantly decreased. Homeostasis model assessment as an index of insulin resistance and the whole body insulin sensitivity index were significantly ameliorated.Conclusions: On the 75 g OGTT, 50 mg Losartan with 12.5 mg HCTZ combinations did not worsen glucose tolerance; moreover, they improved BP, insulin resistance and sensitivity in non-DM Japanese patients with essential hypertension uncontrolled with ARBs alone.

Medical and Biotech [MESH] Definitions

A test to determine the ability of an individual to maintain HOMEOSTASIS of BLOOD GLUCOSE. It includes measuring blood glucose levels in a fasting state, and at prescribed intervals before and after oral glucose intake (75 or 100 g) or intravenous infusion (0.5 g/kg).

Physiological or psychological effects of periods of work which may be fixed or flexible such as flexitime, work shifts, and rotating shifts.

A pathological state in which BLOOD GLUCOSE level is less than approximately 140 mg/100 ml of PLASMA at fasting, and above approximately 200 mg/100 ml plasma at 30-, 60-, or 90-minute during a GLUCOSE TOLERANCE TEST. This condition is seen frequently in DIABETES MELLITUS, but also occurs with other diseases and MALNUTRITION.

ETHINYL ESTRADIOL and NORGESTREL given in fixed proportions. It has proved to be an effective contraceptive (CONTRACEPTIVES, ORAL, COMBINED).

A fixed-ratio combination of amoxicillin trihydrate (see AMOXICILLIN), an aminopenicillin, and potassium clavulanate (see CLAVULANIC ACID), a beta-lactamase inhibitor, used to treat a broad-spectrum of bacterial infections, especially resistant strains.
