Efficacy and Safety Study of the Fixed-dose Combination of Olmesartan + Indapamide When Compared to the Isolated Drugs in the Treatment of Hypertension.

Brainfarma Industria Química e Farmacêutica S/A400 enrolled

Overview

Phase III clinical trial, multicenter of non-inferiority, randomized, single-blind evaluation of fixed-dose combination of olmesartan + indapamide compared to the isolated drugs in the treatment of hypertension.

This study is designed for the treatment of essential hypertension. It is performed in participants of both sexes, over 18 years of age, who have essential hypertension with diastolic blood pressure between 90 mmHg and 110 mmHg. The rationale for studying the fixed dose combination is the possibility to enhance compliance and simplify treatment.

Interventions

fixed-dose of olmesartan 20mg/40 mg + indapamide 1,5 mgDRUG

Fixed-dose of Olmesartan 20mg or 40 mg + Indapamide 1,5 mg oral administration, once a day for 12 weeks. Initially, the participant will be treated with Olmesartan 20mg + Indapamide 1,5 mg. If after 6 weeks the diastolic blood pressure is above 90 mmHg, the dose will be changed to fixed dose of Olmesartan 40 mg + Indapamide 1,5 mg.

Isolated drugs Olmesartan (20 mg or 40 mg) and Indapamide (1,5 mg)DRUG

Isolated drugs Olmesartan (20 mg or 40 mg) and Indapamide (1,5 mg) oral administration, once a day for 12 weeks. Initially, the participant will be treated with Benicar® (olmesartan) 20mg and Natrilix® (indapamide) 1,5 mg. If after 6 weeks the diastolic blood pressure is above 90 mmHg, the dose of Benicar® (olmesartan) will be changed to 40 mg.

Outcomes

Primary Outcomes

Non-inferiority of fixed dose association of olmesartan + indapamide compared to the isolated drugs in the treatment of hypertension.

To evaluate the non-inferiority of the fixed dose association of olmesartan + indapamide to the isolated drugs in the change of the diastolic blood pressure from baseline to 12 week endpoint through Ambulatory Blood Pressure Monitoring.
