Amlodipine and valsartan 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 amlodipine and the ARB class to which valsartan principally belongs. There are no controlled trials demonstrating risk reduction with amlodipine and valsartan 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. Amlodipine and valsartan tablets are indicated for the treatment of hypertension.
Amlodipine and valsartan tablets may be used in patients whose blood pressure is not adequately controlled on either monotherapy.
Amlodipine and valsartan tablets may also be used as initial therapy in patients who are likely to need multiple drugs to achieve their blood pressure goals.
The choice of amlodipine and valsartan tablets as initial therapy for hypertension should be based on an assessment of potential benefits and risks including whether the patient is likely to tolerate the lowest dose of amlodipine and valsartan tablets.
Patients with stage 2 hypertension (moderate or severe) are at a relatively higher risk for cardiovascular events (such as strokes, heart attacks, and heart failure), kidney failure and vision problems, so prompt treatment is clinically relevant. The decision to use a combination as initial therapy should be individualized and should be shaped by considerations such as baseline blood pressure, the target goal and the incremental likelihood of achieving goal with a combination compared to monotherapy. Individual blood pressure goals may vary based upon the patient’s risk.
Data from the high-dose multifactorial study [see Clinical Studies (14)] provide estimates of the probability of reaching a blood pressure goal with amlodipine and valsartan tablets compared to amlodipine or valsartan monotherapy. The figures below provide estimates of the likelihood of achieving systolic or diastolic blood pressure control with amlodipine and valsartan tablets 10 mg/320 mg, based upon baseline systolic or diastolic blood pressure. The curve of each treatment group was estimated by logistic regression modeling. The estimated likelihood at the right tail of each curve is less reliable due to small numbers of subjects with high baseline blood pressures.
For example, a patient with a baseline blood pressure of 160/100 mmHg has about a 67% likelihood of achieving a goal of < 140 mmHg (systolic) and 80% likelihood of achieving < 90 mmHg (diastolic) on amlodipine alone, and the likelihood of achieving these goals on valsartan alone is about 47% (systolic) or 62% (diastolic). The likelihood of achieving these goals on amlodipine and valsartan rises to about 80% (systolic) or 85% (diastolic). The likelihood of achieving these goals on placebo is about 28% (systolic) or 37% (diastolic).

Amlodipine and valsartan tablets are a fixed combination of amlodipine and valsartan.
Amlodipine and valsartan tablets contain the besylate salt of amlodipine, a dihydropyridine calcium-channel blocker (CCB). Amlodipine besylate, USP is a white or almost white powder, slightly soluble in water, freely soluble in methanol, sparingly soluble in ethanol and slightly soluble in 2-propanol. Amlodipine besylate’s chemical name is 3-ethyl-5-methyl (4RS)-2-[(2-aminoethoxy)methyl]-4-(2-chlorophenyl)-6-methyl-1,4-dihydropyridine-3,5-dicarboxylate benzenesulphonate; its structural formula is:
Its molecular formula is C20H25ClN2O5•C6H6O3S and its molecular weight is 567.1.
Valsartan is a nonpeptide, orally active, and specific angiotensin II antagonist acting on the AT1 receptor subtype. Valsartan, USP is a white to almost white amorphous powder, hygroscopic in nature, freely soluble in methanol and practically insoluble in water. Valsartan’s chemical name is N-(1-oxopentyl)-N-[[2’-(1H-tetrazol-5-yl)[1,1’-biphenyl]-4-yl]methyl]-L-valine; its structural formula is:
Its molecular formula is C24H29N5O3 and its molecular weight is 435.52.
Amlodipine and valsartan tablets are formulated in four strengths for oral administration with a combination of amlodipine besylate USP, equivalent to 5 mg or 10 mg of amlodipine free base, with 160 mg, or 320 mg of valsartan, USP providing for the following available combinations: 5 mg/160 mg, 10 mg/160 mg, 5 mg/320 mg and 10 mg/320 mg.
The inactive ingredients for all strengths of the tablets are colloidal silicon dioxide, crospovidone, hypromellose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, red iron oxide, sodium starch glycolate, talc, titanium dioxide and yellow iron oxide.
