The purpose of this study was to evaluate the dose-response relationships of azilsartan, once daily (QD) in participants with mild to moderate uncomplicated essential hypertension.
Hypertension is known to cause multiple organ damage by being combined with not only blood pressure but also other hemodynamics, endocrinological/metabolic abnormalities and genetic factors. This becomes a medically and medical-economically significant problem in Japan The significance of early treatment of hypertension and of long-term control of blood pressure has been increasing year by year.
Takeda Pharmaceutical Company Limited invented TAK-536 (azilsartan), an angiotensin II receptor blocker for decreasing blood pressure. This study investigating the efficacy and safety of azilsartan using candesartan cilexetil, a widely used antihypertensive drug, as a reference control.

|---|---|---|
| Change from Baseline in Sitting Trough Diastolic Blood Pressure (Week 12). | The change between sitting trough clinic diastolic blood pressure measured at week 12 or final visit from diastolic blood pressure measured at baseline. Trough is a time point immediately before the next administration where drug blood concentration is lowest. Mean calculated by using the average (arithmetic mean) of 3 measurements performed at each visit. | Baseline and Week 12. |
