Study Details

Study Description

Brief Summary

The primary objective of this trial is to demonstrate that the fixed dose combination of telmisartan 40mg + amlodipine 10mg (T40/A10) or the fixed dose combination of telmisartan 80mg + amlodipine 10mg (T80/A10) is superior in reducing blood pressure at eight weeks compared with amlodipine 10mg monotherapy (A10) in patients who fail to respond to six weeks treatment with A10.

Inclusion Criteria:

  • willing and able to provide written informed consent.

Exclusion Criteria:
  • pregnancy, breast-feeding, unwilling to use effective contraception (if female of child-bearing potential).

  • uncorrected volume or sodium depletion.

  • primary aldosteronism.

  • hereditary fructose or lactose intolerance.

  • symptomatic congestive heart failure.

  • patients who have previously experienced symptoms characteristic of angioedema during treatment with ACE inhibitors or ARBs.

  • chronic administration of any medication known to affect blood pressure, other than the trial medication.

  • any other clinical condition which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of telmisartan and amlodipine.
