Telmisartan, Amlodipine And Indapamide

Brand Names: Widaplik

Drug Class: Thiazide-like Diuretic

Overview

11 DESCRIPTION Widaplik is a fixed dose combination of telmisartan, amlodipine and indapamide. Widaplik contains telmisartan, a non-peptide angiotensin II receptor (type AT1) antagonist. Telmisartan is chemically described as 4'-[(1,4'-dimethyl-2'-propyl [2,6'-bi-1H-benzimidazol]-1'-yl)methyl]-[1,1'-biphenyl]-2-carboxylic acid.

Mechanism of Action

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action The active ingredients of Widaplik target 3 separate mechanisms involved in blood pressure regulation. Telmisartan Angiotensin II is formed from angiotensin I in a reaction catalyzed by angiotensin-converting enzyme (ACE, kininase II). Angiotensin II is the principal pressor agent of the renin-angiotensin-aldosterone system, with effects that include vasoconstriction, stimulation of synthesis and release of aldosterone, cardiac stimulation, and renal reabsorption of sodium. Telmisartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT 1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland.

Indications

  • 1 INDICATIONS AND USAGE Widaplik (telmisartan/amlodipine/indapamide) is indicated for the treatment of hypertension in adult patients, to lower blood pressure. Widaplik may be used as initial therapy in patients likely to need multiple drugs to achieve blood pressure goals. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including angiotensin II receptor blockers, dihydropyridine calcium...
