hydrochlorothiazide 12.5 MG / telmisartan 80 MG Oral Tablet
What it is used for
Telmisartan and hydrochlorothiazide tablets are indicated for the treatment of hypertension, to lower blood pressure. 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 the classes to which this drug principally belongs. There are no controlled trials demonstrating risk reduction with telmisartan and hydrochlorothiazide tablets. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program's Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC). Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly. Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal. Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy. Telmisartan and hydrochlorothiazide tablets are not indicated for initial therapy for the treatment of hypertension. Telmisartan and hydrochlorothiazide tablets may be used alone or in combination with other antihypertensive agents. Telmisartan and hydrochlorothiazide tablets are combination of an angiotensin II receptor blocker (ARB) and a thiazide diuretic indicated for the treatment of hypertension, alone or with other antihypertensive agents, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions.

Description
Telmisartan and hydrochlorothiazide tablets, USP are a combination of telmisartan, an orally active angiotensin II antagonist acting on the AT 1 receptor subtype, and hydrochlorothiazide, a thiazide diuretic. Telmisartan, USP a non-peptide molecule, is chemically described as 4'-[(1,4'-dimethyl-2'-propyl[2,6'-bi-1H-benzimidazol]-1'-yl)methyl]-[1,1'-biphenyl]-2-carboxylic acid. Its molecular formula is C 33 H 30 N4O 2, its molecular weight is 514.62, and its structural formula is: Telmisartan, USP is a white to slightly yellowish crystalline powder. It is sparingly soluble in methylene chloride, slightly soluble in methanol, and practically insoluble in water. It dissolves in 1M sodium hydroxide. Hydrochlorothiazide, USP is a white or practically white crystalline powder with a molecular weight of 297.74. It is freely soluble in sodium hydroxide solution, in n -butyl amine and in dimethyl formamide. It is also very slightly soluble in water, sparingly soluble in methanol, and insoluble in ether, in chloroform and in dilute mineral acids. Hydrochlorothiazide is chemically described as 6-chloro-3,4-dihydro-2 H -1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Its molecular formula is C 7 H 8 ClN 3 O 4 S 2, and its structural formula is: Telmisartan and hydrochlorothiazide tablets, USP are formulated for oral administration in three combinations of 40 mg/12.5 mg, 80 mg/12.5 mg, and 80 mg/25 mg telmisartan and hydrochlorothiazide, respectively. The tablets contain the following inactive ingredients: colloidal silicon dioxide, hydroxypropyl cellulose, lactose monohydrate, mannitol, meglumine, povidone K 30, sodium hydroxide, sodium stearyl fumarate. As coloring agents, the 80 mg/12.5 mg tablets contain ferric oxide red, and the 40 mg/12.5 mg and 80 mg/25 mg tablets contain ferric oxide yellow. Telmisartan and hydrochlorothiazide tablets are hygroscopic and require protection from moisture. FDA approved dissolution test specifications differ from USP. structure1 struct2
