Prospective comparison of therapeutical attitudes in hypertensive type 2 diabetic patients uncontrolled on monotherapy. A randomized trial: the EDICTA study.

Abstract：

OBJECTIVE:To compare the anti-hypertensive effect of combination therapy versus a single drug regimen schedule (dose-titration or switching to a different drug class) in type 2 diabetic hypertensive patients with inadequate blood pressure (BP) control on monotherapy. DESIGN:Prospective, randomized, open-fashion, parallel study of two therapeutic strategies during an 8-week period. SETTING:Primary care centers in Spain. PARTICIPANTS:A total of 898 men and women with type 2 diabetes mellitus and hypertension, receiving antihypertensive treatment with one single drug and whose BP was > 140 and/or 90 mmHg. INTERVENTION:Patients were randomized to a fixed combination therapy (verapamil 180 mg plus trandolapril 2 mg; Knoll AG, Ludwigshafen, Germany) or continued on a single drug regimen, either increasing the dose of the current drug or switching to a different drug class. MAIN OUTCOME MEASURE:Absolute BP reduction in the two groups of treatment, and the percentage of normalized patients (< 140/90 mmHg) in each group. RESULTS:The diastolic BP (DBP) decrease (5.6 mmHg) was significantly greater in patients treated with combination therapy, compared to patients on monotherapy (2.9 mmHg). The decrease in systolic BP (SBP) was not significantly different (11.1 versus 10.0 mmHg). In addition, a significantly higher number of patients treated with combination therapy (82% versus 74%) reached diastolic BP normalization (< 90 mmHg). CONCLUSIONS:In type 2 hypertensive patients with uncontrolled BP despite anti-hypertensive monotherapy, the change to combination therapy was more effective in attaining DBP control than any monotherapy schedule (either increasing the dose or switching to another different drug class).
