Inclusion Criteria

• Signed Consent of the patient;
• Participants with decompensated essential hypertension, classified into stage 1 (with high or very high cardiovascular risk), stage 2 or stage 3 according to the Brazilian Society of Cardiology (2010), who have never been treated and have indication for drug combination treatment.

Obs: The diagnosis may be established by previous evaluation of two blood pressure measures ≥ 140/90 mmHg, with two months difference between measurements

• Secondary hypertension diagnosis or blood pressure above 190x100 mmHg in the screening/randomization visit;
• Morbid obesity or immunocompromised patients;
• Participants with greater than 10 mmHg difference in the measurements of systolic or diastolic blood pressure between the two arms;
• Participants who do not have the two upper limbs;
• Participants with important electrocardiographic changes;
• Creatinine clearance - less than 60 mL /min;
• History of hypertensive emergencies and cardiovascular and / or moderate to severe cerebrovascular events in the past 6 months;
• Microalbuminuria in urine sample greater than 30 mg/g;
• Patients with history of hypersensitivity to any of the formula compounds;
• Pregnancy or risk of pregnancy and lactating patients;
• Participation in clinical trial in the year prior to this study.
