Amelioration of Albuminuria in Japanese Type 2 Diabetic Patients by Maximal Dose of Candesartan
Open Journal of Endocrine and Metabolic Diseases
It was recently reported that candesartan, an angiotensin II receptor blocker, had a protective effect against cardiovascular events, comparable to that of calcium channel antagonists. Moreover, a renoprotective effect and anti-diabetic action of candesartan had also been demonstrated. However, whether the renoprotective effect of candesartan, especially in diabetes, was dose-dependent or not remain to be fully elucidated. The present study attempted to clarify the dose effect of renoprotection
... t of renoprotection by candesartan in Japanese type 2 diabetic patients. Subjects and Method: In this case series study, we recruited 26 type 2 diabetic patients with albuminuria whose blood pressure did not reach the target BP level (<130/80 mmHg) despite administration of 4 or 8 mg/day of candesartan. Subsequently, these lower doses of candesartan were increased to the maximal dose in Japan, 12 mg/day. Clinical parameters were examined before, at 6 and 12 months after the increase in dose. Results: An ameliorating effect of the increased dose of candesartan on albuminuria and hypertension was distinctly observed. No severe adverse effect was observed. Conclusion: It was highly possible that the maximal dose of candesartan provided more effective renoprotection in hypertensive type 2 diabetic patients initially treated with lower doses of candesartan.
