Efficacy of Telmisartan and the Combination of Telmisartan and Ramipril in type1 Diabetes Patients With Nephropathy

Hypothesis: The angiotensin receptor blocker telmisartan is effective at reduction of albumin excretion rate(AER) in patients with type1 diabetes and micro or macroalbuminuria. Dual blockade with the addition of ramipril an angiotensin receptor blocker gives added efficacy for reduction of AER. ARB telmisartan gives a 24 hr BP lowering effect. Summary: This is an open label cross over study involving 30 patients who were initially treated with Telmisartan 80 mg for eight weeks followed by addition of Ramipril 10 mg for a further eight weeks. Albuminuria reduction and BP reduction with both clinic and ambulatory BP records were studied at the end of each phase.
