Uses
1 INDICATIONS AND USAGE Amlodipine/valsartan/hydrochlorothiazide is 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, hydrochlorothiazide, and the ARB class to which valsartan principally belongs. There are no controlled trials demonstrating risk reduction with amlodipine/valsartan/hydrochlorothiazide.
Dosage
2 DOSAGE AND ADMINISTRATION Dose once-daily. Titrate up to a maximum dose of 10/320/25 mg. (2.1) Amlodipine/valsartan/hydrochlorothiazide may be used as add-on/switch therapy for patients not adequately controlled on any two of the following antihypertensive classes: calcium channel blockers, angiotensin receptor blockers, and diuretics. (2.2) Amlodipine/valsartan/hydrochlorothiazide may be substituted for its individually titrated components. (2.3) 2.1 General Considerations Dose once-daily. The dosage may be increased after 2 weeks of therapy. The full blood pressure lowering effect was achieved 2 weeks after being on the maximal dose of amlodipine/valsartan/hydrochlorothiazide. The maximum recommended dose of amlodipine/valsartan/hydrochlorothiazide is 10/320/25 mg.
Side Effects
6 ADVERSE REACTIONS Most common adverse events (≥2% incidence) are dizziness, peripheral edema, headache, dyspepsia, fatigue, muscle spasms, back pain, nausea and nasopharyngitis. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Strides Pharma Inc at 1-877-244-9825 and/or www.strides.com or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.
Interactions
7 DRUG INTERACTIONS No drug interaction studies have been conducted with amlodipine/valsartan/hydrochlorothiazide and other drugs, although studies have been conducted with the individual components. A pharmacokinetic drug-drug interaction study has been conducted to address the potential for pharmacokinetic interaction between the triple combination, amlodipine/valsartan/hydrochlorothiazide, and the corresponding 3 double combinations. No clinically relevant interaction was observed. Amlodipine Impact of Other Drugs on Amlodipine CYP3A Inhibitors Coadministration with CYP3A inhibitors (moderate and strong) results in increased systemic exposure to amlodipine and may require dose reduction.
Warnings
WARNING: FETAL TOXICITY • When pregnancy is detected, discontinue amlodipine/valsartan/hydrochlorothiazide as soon as possible (5.1). • Drugs that act directly on the renin-angiotensin system can cause injury and death to the developing fetus (5.1). WARNING: FETAL TOXICITY See full prescribing information for complete boxed warning. • When pregnancy is detected, discontinue amlodipine/valsartan/hydrochlorothiazide as soon as possible. 5 WARNINGS AND PRECAUTIONS Hypotension: Correct volume depletion prior to initiation (5.2) Increased angina and/or myocardial infarction (5.3) Monitor renal function and potassium in susceptible patients (5.4, 5.5) Exacerbation or activation of systemic lupus erythematosus (5.7) Observe for signs of fluid or electrolyte imbalance (5.9) Acute angle-closure glaucoma (5.10) 5.1 Fetal Toxicity Valsartan Amlodipine/valsartan/hydrochlorothiazide can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. 4 CONTRAINDICATIONS Do not use in patients with anuria, hypersensitivity to other sulfonamide-derived drugs, or hypersensitivity to any component of this product. Do not coadminister aliskiren with amlodipine/valsartan/hydrochlorothiazide in patients with diabetes [see Drug Interactions (7)].
Pregnancy
8.1 Pregnancy Risk Summary Amlodipine/valsartan/hydrochlorothiazide can cause fetal harm when administered to a pregnant woman. Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Most epidemiologic studies examining fetal abnormalities after exposure to antihypertensive use in the first trimester have not distinguished drugs affecting the renin-angiotensin system from other antihypertensive agents.
Storage
16 HOW SUPPLIED/STORAGE AND HANDLING Amlodipine/valsartan/hydrochlorothiazide is available as film-coated tablets containing amlodipine besylate equivalent to 5 mg or 10 mg of amlodipine free-base with valsartan 160 mg or 320 mg and hydrochlorothiazide 12.5 mg or 25 mg providing for the following available combinations: 5/160/12.5 mg, 10/160/12.5 mg, 5/160/25 mg, 10/160/25 mg or 10/320/25 mg.
