hydrochlorothiazide 12.5 MG / lisinopril 10 MG Oral Tablet
What it is used for
Lisinopril and hydrochlorothiazide tablets are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure lowers the risk of fatal and non-fatal 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 lisinopril and hydrochlorothiazide. 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 1 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. These fixed-dose combinations are not indicated for initial therapy (see DOSAGE AND ADMINISTRATION ). In using lisinopril and hydrochlorothiazide tablets, consideration should be given to the fact that an angiotensin converting enzyme inhibitor, captopril, has caused agranulocytosis, particularly in patients with renal impairment or collagen vascular disease, and that available data are insufficient to show that lisinopril does not have a similar risk. (See WARNINGS.) In considering use of lisinopril and hydrochlorothiazide tablets, it should be noted that Black patients receiving ACE inhibitors have been reported to have a higher incidence of angioedema compared to non-Black. (See WARNINGS, Head and Neck Angioedema.)

Description
Lisinopril and hydrochlorothiazide tablets combine an angiotensin converting enzyme inhibitor, lisinopril, and a diuretic, hydrochlorothiazide. Lisinopril, a synthetic peptide derivative, is an oral long-acting angiotensin converting enzyme inhibitor. It is chemically described as (S)-1-[N2-(1-carboxy-3-phenylpropyl)-L-lysyl]-L-proline dihydrate. Its empirical formula is C 21 H 31 N 3 O 5
2H 2 O and its structural formula is: Lisinopril, USP is a white to off-white, crystalline powder, with a molecular weight of 441.52. It is soluble in water, sparingly soluble in methanol, and practically insoluble in ethanol. Hydrochlorothiazide is 6-chloro-3,4-dihydro-2H-1,2,4-benzothiadiazine-7-sulfonamide 1,1-dioxide. Its empirical formula is C 7 H 8 ClN 3 O 4 S 2 and its structural formula is: Hydrochlorothiazide, USP is a white, or practically white, crystalline powder with a molecular weight of 297.73, which is slightly soluble in water, but freely soluble in sodium hydroxide solution. Lisinopril and hydrochlorothiazide tablets, USP are available for oral use in three tablet combinations of lisinopril with hydrochlorothiazide: lisinopril and hydrochlorothiazide tablets 10 mg/12.5 mg containing 10 mg lisinopril and 12.5 mg hydrochlorothiazide; lisinopril and hydrochlorothiazide tablets 20 mg/12.5 mg containing 20 mg lisinopril and 12.5 mg hydrochlorothiazide; and, lisinopril and hydrochlorothiazide tablets 20 mg/25 mg containing 20 mg lisinopril and 25 mg hydrochlorothiazide. Inactive Ingredients: 10 mg/12.5 mg Tablets - dibasic calcium phosphate dihydrate, magnesium stearate, mannitol, pregelatinized starch. 20 mg/12.5 mg Tablets - dibasic calcium phosphate dihydrate, magnesium stearate, mannitol, pregelatinized starch, yellow ferric oxide. 20 mg/25 mg Tablets - dibasic calcium phosphate dihydrate, magnesium stearate, mannitol, pregelatinized starch, red ferric oxide. picture 1 picture 2
