Key Takeaway
Consider Sdamlo as a calcium channel blocker for hypertension in adults and children ≥6 years and for CAD in adults.

The FDA approved Sdamlo (amlodipine) on July 24, 2025, for the treatment of hypertension in adults and pediatric patients aged 6 years and older, and for coronary artery disease in adults, including chronic stable angina, vasospastic angina, and angiographically documented CAD without heart failure or ejection fraction <40%. Sdamlo is a calcium channel blocker that can be used alone or in combination with other antihypertensive and antianginal agents. The approval provides an additional option for managing hypertension and CAD, conditions that affect millions of patients. Lowering blood pressure with Sdamlo reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions, as established in trials of various antihypertensive classes.

Clinical Details (Mechanism · Dosing · Trial Data · Warnings)
Mechanism of Action

Sdamlo is a calcium channel blocker. It inhibits the influx of calcium ions across cardiac and vascular smooth muscle cells, leading to vasodilation and reduced peripheral vascular resistance, which lowers blood pressure. It also dilates coronary arteries and arterioles, improving oxygen supply to the myocardium.

Indication & Patient Population

Sdamlo is indicated for: - Hypertension: to lower blood pressure in adults and pediatric patients 6 years of age and older. - Coronary Artery Disease in adults: chronic stable angina, vasospastic angina (Prinzmetal's or variant angina), and angiographically documented CAD in patients without heart failure or an ejection fraction <40%.

Dosing & Administration

- Adults: Starting dose 5 mg orally once daily; maximum 10 mg once daily. Small, fragile, elderly, or hepatic impairment patients may start at 2.5 mg once daily. For angina, 5-10 mg once daily; most require 10 mg. For CAD, 5-10 mg once daily; most require 10 mg. - Pediatric (6-17 years): Starting dose 2.5-5 mg orally once daily; doses >5 mg daily not studied. - Titrate based on blood pressure goals; wait 7-14 days between steps.

Place in Therapy

Sdamlo is a calcium channel blocker that may be used alone or in combination with other antihypertensive and antianginal agents. It is a first-line option for hypertension and CAD, with proven benefits in reducing cardiovascular events. In black patients, some antihypertensives have smaller effects as monotherapy; Sdamlo may be combined with other agents. For pediatric hypertension, doses above 5 mg have not been studied.

1 INDICATIONS AND USAGE Sdamlo is a calcium channel blocker and may be used alone or in combination with other antihypertensive and antianginal agents for the treatment of: Hypertension ( 1.1 ) Sdamlo is indicated for the treatment of hypertension, to lower blood pressure in adults and pediatric patients 6 years of age and older. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. Coronary Artery Disease in adults ( 1.2 ) Chronic Stable Angina Vasospastic Angina (Prinzmetal's or Variant Angina) Angiographically Documented Coronary Artery Disease in patients without heart failure or an ejection fraction <40% 1.1 Hypertension Sdamlo is indicated for the treatment of hypertension, to lower blood pressure in adults and pediatric patients 6 years of age and older. 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. 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. Sdamlo may be used alone or in combination with other antihypertensive agents. 1.2 Coronary Artery Disease (CAD) Chronic Stable Angina Sdamlo is indicated for the symptomatic treatment of chronic stable angina in adults. Sdamlo may be used alone or in combination with other antianginal agents. Vasospastic-Angina (Prinzmetal's or Variant Angina) Sdamlo is indicated for the treatment of confirmed or suspected vasospastic angina in adults. Sdamlo may be used as monotherapy or in combination with other antianginal agents. Angiographically Documented CAD In adult patients with recently documented CAD by angiography and without heart failure or an ejection fraction <40%, Sdamlo is indicated to reduce the risk of hospitalization for angina and to reduce the risk of a coronary revascularization procedure.
