Effectiveness and Safety of Combination of Nebivolol and Zofenopril in Hypertensive patIents Versus Each Monotherapy

This is a study with 2 periods (a run-in period of 4 weeks and an assessment period of 8 weeks). Grade 1-2 hypertensive patients (blood pressure \[BP\] ranging from ≥140/90 mmHg to ≤179/109 mmHg) on treatment with any angiotensin converting enzyme-inhibitors (ACEi) or beta blockers (BBs) including ZOF 30 mg or NEB 5 mg respectively will be screened for eligibility (Visit 1). On the same day, the eligible patients will enter into a run-in period after Screening, during which: * Patients on ZOF 30 mg or NEB 5 mg will continue the same therapy for 4 weeks * Patients on any other ACE-i will be assigned to monotherapy with ZOF 30 mg while patients on any other BB will be assigned to monotherapy with NEB 5 mg, respectively, for 4 weeks. After the 4 weeks of monotherapy in the run-in period, if BP at Visit 2, remains uncontrolled (sitting Systolic Blood Pressure/Diastolic Blood Pressure \>130/80 mmHg) despite an adherence to the treatments ranging from 80% to 120%, the patients will start treatment (Week 0, Visit 2) with the extemporaneous combination of NEB 5 mg/ZOF 30 mg (NEB/ZOF) and will be assessed for further 8 weeks (assessment period). If the patients, at Visit 2 after the Run-In period, have controlled BP (sitting Systolic Blood Pressure/Diastolic Blood Pressure ≤130/80 mmHg), and/or do not tolerate the treatment, and/or do not maintain the adherence to the therapy (range from 80% to 120%), these patients will not be continued further in the study. At the end of the assessment period (Visit 3) the anti-hypertensive effect of the extemporaneous combination of NEB 5 mg and ZOF 30 mg will be evaluated. A total number of 290 patients will be screened considering 25% of drop-out rate, to obtain approximately 216 completed patients at the end of the study.
