Introduction. Hypertension in type 2 diabetes represents a strong risk factor for cardiovascular events. Either calcium channel blockers or angiotensin receptor blockers (ARBs) may reduce insulin resistance. One of the ARBs, telmisartan (Telm) acting as a PPAR agonist, significantly reduces HbA1C levels.The aim of this study was the comparison of the effects on glycaemic control of amlodipine (Aml) and Telm in hypertensive type 2 diabetic patients.

Materials and methods. Forty diabetic hypertensive subjects were assigned to two groups. Group A: rosiglitazone (RSG) 4 mg + Telm 80 mg; Group B: RSG 4 mg + Aml 10 mg. All the patients were already treated with metformin, but not with antihypertensive drugs.

Results. After four months treatment, both groups showed a significant reduction of mean blood pressure (Group A: - 13.5%; Group B: - 13.3%) and a positive influence on glycaemic control and insulin resistance. Lower values of glucose, HbA_1C, HOMA index and higher adiponectin levels were observed in Group A compared to Group B.

Conclusions. In type 2 diabetic hypertensive patients, the association of Telm 80 mg and RSG 4 mg seems to display a metabolic advantage compared to Aml 10 mg.The simultaneous beneficial effects on blood pressure and insulin sensitivity may confer make Telm particularly suitable in the treatment of the metabolic syndrome.
