A prospective randomised study to compare a fixed dose combination of telmisartan 80 mg plus hydrochlorothiazide 25 mg with a fixed dose combination of telmisartan 80 mg plus hydrochlorothiazide 12.5 mg in patients with uncontrolled hypertension who fail to respond adequately to treatment with a fixed dose combination of telmisartan 80 mg plus hydrochlorothiazide 12.5 mg.

diagnosis of essential hypertension and currently taking between one and three antihypertensive medications at a stable dose for at least four weeks before entry.
blood pressure not adequately controlled on existing antihypertensive treatment before entry. (Inadequate control defined as seated DBP = 95 mmHg on one current antihypertensive medication or DBP = 90 mmHg on two or more current antihypertensive medications).
failure to respond to six weeks treatment with T80/H12.5 fixed-dose combination therapy. (Failure to respond defined as seated DBP = 90 mmHg at six weeks.)
willing and able to provide written informed consent

known or suspected secondary hypertension.
mean SBP equal to or greater than 200 mmHg at the end of the run-in treatment period.
severe hepatic or renal impairment (including bilateral renal artery stenosis, renal artery stenosis in a solitary kidney or patients post-renal transplant or with only one functioning kidney)
clinically relevant hypokalaemia or hyperkalaemia.
uncorrected volume or sodium depletion.
primary aldosteronism.
hereditary fructose intolerance.
patients who have previously experienced symptoms characteristic of angioedema during treatment with any ACE inhibitors or angiotensin-II receptor antagonist.
history of drug or alcohol dependency within the previous six months.
current treatment with any antihypertensive agent that cannot be safely stopped (investigator’s decision) by the start of the run-in treatment period or chronic administration of any medication known to affect blood pressure, other than the trial medication.
concurrent participation in another clinical trial or any investigational therapy within thirty days prior to signing the consent form.
hypertrophic obstructive cardiomyopathy, hemodynamically relevant stenosis of the aortic or mitral valve.
known allergic hypersensitivity to any component of the formulations under investigation (including known hypersensitivity to any angiotensin-II receptor antagonist, hydrochlorothiazide or sulphonamide-derived drugs).
concomitant therapy with lithium, cholestyramine or colestipol resins.
any other clinical condition which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of telmisartan or hydrochlorothiazide.
