Objectives

Narrative objectives1

To compare the efficacy of an increased regimen of Ca channel blockers and adding diuretics for treating the blood pressure in patients with essential hypertension who failed to achieve the target blood pressure by a combination therapy with ARBs and Ca channel blockers
We examine non-inferiority of Irbesartan 100mg/Amlodipine 10mg to triple combination with Amlodipine 10mg /Irbesartan 100mg /Indapamide 1mg for reduction of blood pressure.

Results

High-dose CCBs combined with ARBs and a triple combination with diuretics combined with standard-dose CCB/ARBs produced
a similar efficacy in reducing the BP. Both
combination therapies can be used safely and effectively in hypertensive patients uncontrolled by standard doses of ARBs and CCBs.

Baseline Characteristics

Japanese hypertensive patients, who had not attained the BP goal with a combination therapy with usual dosages of ARBs plus CCB

Participant flow

A total of 97 patients were considered to be eligible for the study;
however, three patients who met the exclusion criteria were excluded.

Adverse events

No adverse events

Outcome measures

The primary end point is a change in the SBP/DBP after a 12-week treatment. The secondary end points are BP changes after the 24-week treatment period, and laboratory values.
