Use in Specific Populations

Special Populations: Hepatic Function Impairment

Felodipine clearance is reduced about 60% in patients with hepatic impairment.

Special Populations: Elderly

Plasma concentrations of felodipine increase with advancing age. Clearance of felodipine in elderly hypertensive patients was 45% of that observed in young volunteers. Steady-state mean area under curve in young patients was 39% of that observed in elderly patients.

Use: Labeled Indications

Hypertension: Management of hypertension

Use: Off Label

Chronic stable anginaayes

Data from randomized, double-blind, placebo-controlled trials support the use of felodipine for the management of chronic stable angina, primarily in patients who continue to be symptomatic on an optimal dose of a beta-blocker Dunselman 1997, Emanuelsson 1999, Rønnevik 1995.

Based on the 2012 American College of Cardiology Foundation/American Heart Association (ACCF/AHA) guideline for the diagnosis and management of patients with stable ischemic heart disease, a dihydropyridine calcium channel blocker (eg, felodipine) is an effective and recommended agent in the management of chronic stable angina. A beta-blocker is the preferred initial therapy for chronic stable angina; however, a dihydropyridine calcium channel blocker (eg, felodipine) may be added if there are ongoing anginal symptoms or may be used as alternative therapy if there are contraindications or unacceptable adverse effects with beta-blockade.

Contraindications

Hypersensitivity to felodipine or any component of the formulation.

Canadian labeling: Additional contraindications (not in US labeling): Hypersensitivity to other dihydropyridines; women of childbearing potential, in pregnancy, and during lactation.

Dosage and Administration

Dosing: Adult

Chronic stable angina (alternative agent) (off-label use): Note: A beta-blocker is the preferred initial therapy; if there are ongoing symptoms on beta-blocker therapy, a calcium channel blocker (typically a dihydropyridine [eg, felodipine]) may be added; felodipine may be used as an alternative therapy if there are contraindications or unacceptable adverse effects with beta-blockade (ACC/AHA [Fihn 2012]).

Oral: Initial: 5 to 10 mg once daily; if initiated at 5 mg, increase dose to 10 mg once daily as tolerated after 2 to 4 weeks (Dunselman 1997; Emanuelsson 1999; Rønnevik 1995)

Hypertension: Note: For initial treatment in patients with blood pressure ≥20/10 mm Hg above goal, may be used in combination with another appropriate agent (eg, ACE inhibitor, ARB, or thiazide diuretic). For patients <20/10 mm Hg above goal, some experts recommend an initial trial of monotherapy; however, over time, many patients will require combination therapy (ACC/AHA [Whelton 2017]; Mann 2019).

Oral: Initial: 2.5 to 5 mg once daily; titrate every 1 to 2 weeks as needed based on patient response; usual dose range: 2.5 to 10 mg once daily (ACC/AHA [Whelton 2017]; Mann 2019)

Dosing: Geriatric

Hypertension: Oral: Consider lower initial doses (eg, 2.5 mg once daily) and titrate at no less than 2-week intervals to response (Aronow 2011).

Dosing: Pediatric

Hypertension: Limited data available: Children ≥6 years and Adolescents: Oral: Initial: 2.5 mg once daily; may increase as needed at 2-week intervals to a maximum daily dose: 10 mg/day (AAP [Flynn 2017]; NHLBI 2011; Trachtmen 2003)

Administration

Oral: Swallow tablet whole; tablet should not be divided, crushed, or chewed. May be administered without food or with a small meal that is low in fat and carbohydrates.

Dietary Considerations

May be taken with a small meal that is low in fat and carbohydrates.

Storage

Store below 30°C (86°F); protect from light.

Warnings/Precautions

Concerns related to adverse effects:

  • Angina/MI: Increased angina and/or MI has occurred with initiation or dosage titration of dihydropyridine calcium channel blockers; reflex tachycardia may occur resulting in angina and/or MI in patients with obstructive coronary disease especially in the absence of concurrent beta-blockade.
  • Hypotension/syncope: Symptomatic hypotension with or without syncope can rarely occur; blood pressure must be lowered at a rate appropriate for the patient's clinical condition.
  • Peripheral edema: The most common side effect is peripheral edema (dose dependent); occurs within 2 to 3 weeks of starting therapy.

Disease-related concerns:

  • Aortic stenosis: Use with extreme caution in patients with severe aortic stenosis; may reduce coronary perfusion resulting in ischemia.
  • Heart failure: The ACC/AHA heart failure guidelines recommend to avoid use in patients with heart failure (HF) due to lack of benefit and/or worse outcomes with calcium channel blockers in general (ACC/AHA [Yancy 2013]).
  • Hepatic impairment: Use with caution in patients with hepatic impairment; may require lower starting dose.
  • Hypertrophic cardiomyopathy (HCM) with outflow tract obstruction: Use with caution in patients with HCM and outflow tract obstruction since reduction in afterload may worsen symptoms associated with this condition.

Special populations:

  • Elderly: Initiate at a lower dose in the elderly.

Dosage forms specific issues:

  • Lactose: May contain lactose; if necessary, consider alternative agents in patients intolerant of lactose.

Concurrent drug therapy issues:

  • Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Monitoring Parameters

Blood pressure, heart rate

Hypertension: The 2017 Guideline for the Prevention, Detection, Evaluation, and Management of High Blood Pressure in Adults (ACC/AHA [Whelton 2017]):

Confirmed hypertension and known CVD or 10-year atherosclerotic cardiovascular disease (ASCVD) risk ≥10%: Target blood pressure <130/80 mm Hg is recommended.

Confirmed hypertension without markers of increased ASCVD risk: Target blood pressure <130/80 mm Hg may be reasonable.

Diabetes and hypertension: The American Diabetes Association (ADA) guidelines (ADA 2019):

Patients 18 to 65 years of age, without ASCVD, and 10-year ASCVD risk <15%: Target blood pressure <140/90 mm Hg is recommended.

Patients 18 to 65 years of age and known ASCVD or 10-year ASCVD risk >15%: Target blood pressure <130/80 mm Hg may be appropriate if it can be safely attained.

Patients >65 years of age (healthy or complex/intermediate health): Target blood pressure <140/90 mm Hg is recommended.

Patients >65 years of age (very complex/poor health): Target blood pressure <150/90 mm Hg is recommended.

Pregnancy Considerations

Adverse events were observed in animal reproduction studies.

Chronic maternal hypertension may increase the risk of birth defects, low birth weight, preterm delivery, stillbirth, and neonatal death. Actual fetal/neonatal risks may be related to duration and severity of maternal hypertension. Untreated hypertension may also increase the risks of adverse maternal outcomes, including gestational diabetes, myocardial infarction, preeclampsia, stroke, and delivery complications (ACOG 203 2019).

Calcium channel blockers may be used to treat hypertension in pregnant women; however, agents other than felodipine are more commonly used (ACOG 203 2019; ESC [Regitz-Zagrosek 2018]). Females with preexisting hypertension may continue their medication during pregnancy unless contraindications exist (ESC [Regitz-Zagrosek 2018]).
