  • 1.Patients with severe hypertension (mean seated SBP =180 mmHg and/or a mean seated DBP =110 mmHg).
  • 2.Patients who have a history of secondary hypertension (including primary aldosteronism, renovascular hypertension, pheocromocytoma, etc.).
  • 3.Patients receiving three or more antihypertensive drugs. Dual fixed dose combination therapy will be considered as two antihypertensive drugs.
  • 4.Administration of any agent indicated for the treatment of hypertension after Visit 1, with the permitted exception of those antihypertensive medications requiring tapering down (e.g. beta-blocker and/or clonidine) commencing with Visit 1.
  • 5.Known moderate or malignant retinopathy. Moderate defined as: retinal signs of hemorrhage, microaneurysm, cotton-wool spot, hard exudates, or a combination thereof; malignant defined as: signs of moderate retinopathy plus swelling of the optic disk.
  • 6.Known or suspected contraindications, including history of allergy or hypersensitivity to ARBs, CCBs, or to drugs with similar chemical structures.
  • 7.History of cerebrovascular accident, thrombotic stroke, or transient ischemic attack.
  • 8.Significant history of coronary artery disease (CAD) such as any history of myocardial infarction (MI), angina pectoris, and all types of revascularization procedures.
  • 9.History of or diagnosis of congestive heart failure Grade II-IV according to the NYHA classification.
  • 10.Clinically significant valvular heart disease.
  • 11.All patients with Type 1 diabetes mellitus and those patients with Type 2 diabetes mellitus who, in the opinion of the investigator, are not well controlled.

  • 12.Concomitant potentially life threatening arrhythmia or symptomatic arrhythmia.
  • 13.Second or third degree heart block with or without a pacemaker.

  • 18.Any condition, not identified in the protocol, that, in the opinion of the investigator or the Novartis monitor, places the patient at higher risk from his/her participation in the study, or is likely to prevent the patient from complying with the requirement of the study or completing the trial period.
