Insulin resistance is often complicated with hypertension. AGE and inflammation play important roles in insulin resistance. Some studies reported that pioglitazone, insulin sensitizer, is effective for patients with insulin resistance, however, the mechanisms are still unclear. The aim of this study to evaluate the effect of pioglitazone compared with glimepiride on AGE, inflammatory cytokines and cardiac markers (BNP and echo) in hypertensive patients during oral glucose tolerance test.

Condition Intervention Phase

Study Design: Intervention Model: Single Group Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: Effects of Pioglitazone and Glimepiride in Hypertensive Patients - Relationship With AGE, Inflammatory Cytokines and Cardiac Markers -
