Dosing and Administration

Katerzia Enables Accurate, Consistent and Easy Dosing

Convenient, user-friendly oral suspension

  • Simply shake before dosing; Katerzia is ready-to-use.
  • No additional preparation required by the pharmacist or caregiver.
  • Eliminates compounding using tablets allowing for a reduction of potential errors. 

FDA-Approved Dosing

  • Katerzia Oral Suspension contains 1 mg/mL of amlodipine (equivalent to 1.30 mg of amlodipine benzoate) in a white to off-white aqueous suspension.
  • Supplied as 150 mL in a 185-cc high-density polyethylene (HDPE) bottle with a child-resistant cap and tamper-evident seal.

Dosing for Pediatric Patients 6 Years of Age and Older with Hypertension

  • The effective antihypertensive oral dose of Katerzia in pediatric patients ages 6 to 17 years of age is 2.5 mg to 5 mg once daily.
  • Doses above 5 mg daily have not been studied in pediatric patients.
  • Dosage should be adjusted based on blood pressure response.
  • The effect of amlodipine on blood pressure is not known in pediatric patients less than 6 years of age.

Dosing for Adults with Hypertension

  • The recommended starting dose for adult hypertension is 5 mg once daily with maximum dose of 10 mg once daily.
  • Small, fragile, or elderly patients, or patients with hepatic insufficiency, may be started on 2.5 mg once daily, and this dose may be used when adding Katerzia to other antihypertensive therapy.
  • Adjust dosage according to blood pressure goals.

Dosing for Adults with Angina

  • The recommended dose for chronic stable or vasospastic angina is 5 to 10 mg once daily, with the lower dose suggested in the elderly and in patients with hepatic insufficiency.
  • Most patients will require 10 mg for adequate effect.

Dosing for Adults with Coronary Artery Disease

  • The recommended dose range for patients with coronary artery disease is 5 to 10 mg once daily.
  • In clinical studies, the majority of patients required 10 mg once daily.

Katerzia Administration and Storage 

  • Simply shake prior to administration.
  • Ask your pharmacist for an appropriate dosing device.
  • Keep refrigerated at 2°C to 8°C/36°F to 46°F. Avoid freezing and excessive heat. Protect from light.
  • Good until the date on the bottle.

IMPORTANT SAFETY INFORMATION

INDICATIONS

KATERZIA is a calcium channel blocker and may be used alone or in combination with other antihypertensive and antianginal agents 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:
    • 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%.

ADDITIONAL IMPORTANT SAFETY INFORMATION

Contraindications:

Katerzia is contraindicated in patients with known sensitivity to amlodipine or to the inactive ingredients.

Warnings and Precautions:

  • Symptomatic hypotension is possible, particularly in patients with severe aortic stenosis. Because of the gradual onset of action, acute hypotension is unlikely.
  • Worsening angina and acute myocardial infarction can develop after starting or increasing the dose of amlodipine, particularly in patients with severe obstructive coronary artery disease.
  • Because amlodipine is extensively metabolized by the liver, and the plasma elimination half-life is 56 hours in patients with impaired hepatic function, titrate slowly when administering Katerzia to patients with severe hepatic impairment.

Adverse Reactions: See full Prescribing Information for additional adverse reactions.

  • The most common dose-related adverse reaction to amlodipine is edema.
  • Incidents of dose-related dizziness, flushing, and palpitation also have been observed.
  • For several reported adverse experiences that appear to be dose- and drug-related (edema, flushing, palpitations), there was a higher incidence associated with amlodipine treatment in women than in men.
  • Other adverse experiences not dose-related but reported are fatigue, nausea, abdominal pain, and somnolence.

Drug Interactions:

Impact of Amlodipine on Other Drugs

  • Co-administration of simvastatin with amlodipine increases the systemic exposure of simvastatin. Limit the dose of simvastatin in patients on amlodipine to 20 mg daily.
  • Amlodipine may increase the systemic exposure of cyclosporine or tacrolimus when co-administered. Frequent monitoring of trough blood levels of cyclosporine and tacrolimus is recommended. Adjust the dose accordingly when appropriate.

Impact of Other Drugs on Amlodipine

  • 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.
  • Blood pressure should be closely monitored when amlodipine is co-administered with CYP3A inducers.

Important Limitations in Specific Populations:

Pediatric Use

  • The effective antihypertensive oral dose in pediatric patients ages 6 to 17 years is 2.5 mg to 5 mg once daily. Doses in excess of 5 mg daily have not been studied in pediatric patients.
  • The effect of amlodipine in patients less than 6 years of age is not known.

Geriatric Use

  • In general, dose selection for elderly patients should be cautious, usually starting with a lower initial dose.

Hepatic Impairment

  • A lower initial dose may be required for patients with hepatic insufficiency.

Pregnancy

  • Limited data on post-marketing use of amlodipine in pregnant women are not sufficient to inform a drug-associated risk for major birth defects or miscarriages. There are risks to the mother and fetus associated with poorly controlled hypertension during pregnancy. See full Prescribing Information.

Lactation

  • Limited available data from a published clinical lactation study reports that amlodipine is present in human milk. No adverse effects of amlodipine on the breastfed infant have been observed.

SHAKE BEFORE USING.

Refrigerate at 2°C to 8°C/36°F to 46°F. Avoid freezing and excessive heat. Protect from light.
