• •Concerning concomitant diseases
• •History of renal disease: Known renal impairment: Patients having a creatinine clearance value classifying them as moderate or severe renal failure (using national or international classification of chronic kidney disease), whatever the method for calculation used (Modification of Diet in Renal Disease (MDRD) or Cockcroft or any other Estimated Glomerular Filtration Rate (eGFR) formula), or bilateral renal artery stenosis or stenosis to a solitary kidney.

• •Known complicated liver disease (for example: chronic hepatitis, cirrhosis, hepatic encephalopathy…).
• •Chronic pancreatitis.
• •Endocrine diseases: uncontrolled dysthyroidia, Cushing's syndrome, acromegalia, hyperparathyroidia.

• •History of angioneurotic oedema.
• •Concerning concomitant medications
• •β-blockers even if used for other reason than HT, in order to avoid the AE related to the immediate switch during selection visit.
• •Antihypertensive treatments having central mechanism of action in order to avoid possible rebound effect at a full immediate stop at the randomization.
• •Antiarrhythmic treatments in order to avoid possible interactions with bisoprolol.
• •Inability to stop any of the medications listed in the prohibited concomitant medication list.
• •Potassium supplement at selection and inclusion visit.
• •Drugs contraindicated with the study treatments as defined in the Summaries of Product Characteristics of each study drugs
• •Concerning contra-indications to treatment with amlodipine, bisoprolol or perindopril

• •* amlodipine or any other dihydropyridine and calcium inhibitors;
• •* perindopril or any other ACE inhibitor;
• •* bisoprolol or other beta-blockers;
• •* any of the excipients of the study drugs.
• •Respect of the previous selection and non-selection criteria.
