Official title: Randomized, Phase 3, Multicenter, Double-blind, Double Dummy, Evaluating the Effect of Combined Treatment of Indapamide 1.5mg/Losartan 50mg and Indapamide 1.5mg/Losartan 100mg, Compared With 1.5 mg Indapamide Monotherapy in the Treatment of Hypertension

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Changes in systemic blood pressure measurements during 12 weeks

Secondary outcome:

Percentage (%) of patients with blood pressure < 140 / 90 mmHg during 12 weeks, will be obtained comparing the differences between initial blood pressure (initial visit) and final (final visit).

Percentage (%) of patients excluded from the study because of treatment failure
