Telmisartan in the treatment of Cohen-Rosenthal Diabetic Hypertensive rats: the benefit of PPAR-gamma agonism.

Abstract

The antihypertensive and hypoglycemic effects of telmisartan, which has dual angiotensin II antagonist-PPAR-gamma agonist properties, was studied in Cohen-Rosenthal Diabetic Hypertensive rats (CRDH), a model in which hypertension, insulin resistance, and diabetes co-exist. CRDH, Cohen-diabetic rats (CDR), and SHR received telmisartan (3 mg/kg/day in drinking water) for five months. Telmisartan significantly lowered systolic and diastolic BP in SHR and CRDH, independent of body weight, and remained fairly constant in controls throughout the experiment. Blood glucose levels fell rapidly in the treated animals and remained steady in controls. Results indicate that telmisartan is a prototype of a new approach to treating coexisting diabetes and hypertension.
