Objectives

Narrative objectives1

Combinations of angiotensin II type 1 receptor blockers (ARBs) and calcium channel blockers (CCBs) are recommended by various guidelines for the treatment of high blood pressure. Many kinds of single-pill fixed-dose combinations of ARBs and CCBs are available for clinical use in Japan. It is still controversial what types of single-pill fixed-dose combinations of ARBs and CCBs are useful. Therefore, we compared the efficacies and safety of single-pill fixed-dose combinations of ARBs and CCBs (azilsartan and amlodipine vs. valsartan and amlodipine or irbesartan and amlodipine).

Interventions/Control_1

The patients receive a single-pill fixed-dose combination of a single-pill fixed-dose combination of azilsartan/amlodipine and treated for 16 weeks. If the patient dose not reach the target office blood pressure at 8 weeks according to Japanese Society of Hypertension Guideline 2014, they received double doses of amlodipine.

Interventions/Control_2

The patients receive a single-pill fixed-dose combination of valsartan/amlodipine or irbesartan/amlodipine and treated for 16 weeks. If the patient dose not reach the target office blood pressure at 8 weeks according to Japanese Society of Hypertension Guideline 2014, they received double doses of amlodipine.
