Cardioprotective effects of telmisartan in uncomplicated and complicated hypertension.
The development of angiotensin II receptor blockers (ARB) as a new class of drugs for the management of hypertension has elicited the attention of many clinicians worldwide with the aim of improving blood pressure (BP) control as well as cardiovascular protection. Among ARB telmisartan has been shown to be characterised by an antihypertensive efficacy fully covering the 24-hour period, thereby allowing to antagonise the adverse effects of early morning BP rise on cardiovascular risk. Other specific effects of the drug are represented by its favourable metabolic profile (particularly on insulin sensitivity) and neutral effects on sympathetic cardiovascular function. These properties are coupled with cardioprotective effects, documented by the evidence that the drug: 1) is effective in favouring the regression of cardiac and vascular organ damage, 2) reduces arterial stiffness and improves vascular distensibility and 3) reverses the endothelial dysfunction typical of the hypertensive state particularly when complicated by renal failure, diabetes, obesity or metabolic syndrome. Several of these properties can account for the results of the ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial (ONTARGET), documenting the beneficial effects on the drug on cardiovascular morbidity and mortality.
