Uses
1 INDICATIONS AND USAGE NORLIQVA is a calcium channel blocker for the treatment of: Hypertension ( 1.1 ) NORLIQVA is indicated for the treatment of hypertension in adults and children 6 years of age and older, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. Coronary Artery Disease ( 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 NORLIQVA® is indicated for the treatment of hypertension, to lower blood pressure in adults and children 6 years of age and older.
Dosage
2 DOSAGE AND ADMINISTRATION Adult recommended starting dose: 5 mg orally once daily with a maximum of 10 mg orally once daily. ( 2.1 ) Small, fragile, or elderly patients, or patients with hepatic insufficiency may be started on 2.5 mg orally once daily. ( 2.1 ) Pediatric starting dose: 2.5 mg to 5 mg orally once daily. ( 2.2 ) 2.1 Adults The usual initial antihypertensive oral dose of NORLIQVA is 5 mg orally once daily, and the maximum dose is 10 mg orally once daily. Small, fragile, or elderly patients, or patients with hepatic insufficiency may be started on 2.5 mg orally once daily and this dose may be used when adding NORLIQVA to other antihypertensive therapy [see Clinical Pharmacology (12.3) ] . Adjust dosage according to blood pressure goals.
Side Effects
6 ADVERSE REACTIONS The most common adverse reactions are nausea, anorexia, and bloating. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact CMP Pharma, Inc. at 1-844-321-1443 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Amlodipine has been evaluated for safety in more than 11,000 patients in U.S. and foreign clinical trials. In general, treatment with amlodipine was well-tolerated at doses up to 10 mg daily.
Interactions
7 DRUG INTERACTIONS Do not exceed doses greater than 20 mg daily of simvastatin. ( 7.2 ) 7.1 Impact of Other Drugs on Amlodipine CYP3A Inhibitors Co-administration with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction. Monitor for symptoms of hypotension and edema when amlodipine is co-administered with CYP3A inhibitors to determine the need for dose adjustment [see Clinical Pharmacology (12.3) ] . CYP3A Inducers No information is available on the quantitative effects of CYP3A inducers on amlodipine. Blood pressure should be closely monitored when amlodipine is co-administered with CYP3A inducers.
Warnings
5 WARNINGS AND PRECAUTIONS Symptomatic hypotension is possible, particularly in patients with severe aortic stenosis. However, acute hypotension is unlikely. ( 5.1 ) Worsening angina and acute myocardial infarction can develop after starting or increasing the dose of NORLIQVA, particularly in patients with severe obstructive coronary artery disease. ( 5.2 ) Titrate slowly in patients with severe hepatic impairment. ( 5.3 ) 5.1 Hypotension Symptomatic hypotension is possible, particularly in patients with severe aortic stenosis. Because of the gradual onset of action, acute hypotension is unlikely. 4 CONTRAINDICATIONS NORLIQVA is contraindicated in patients with sensitivity to amlodipine. Sensitivity to amlodipine ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary: The limited available data based on post-marketing reports with amlodipine use in pregnant women are not sufficient to inform a drug-associated risk for major birth defects and miscarriage. There are risks to the mother and fetus associated with poorly controlled hypertension in pregnancy [see Clinical Considerations] In animal reproduction studies, there was no evidence of adverse developmental effects when pregnant rats and rabbits were treated orally with amlodipine maleate during organogenesis at doses approximately 10 and 20-times the maximum recommended human...
