Terminal half-life 33–36 hours (anuric patients up to 110 hours); requires dose adjustment in renal impairment.
Terminal elimination half-life is 36-48 hours in adults with normal renal function; prolonged to 3.5-5 days in anephric patients due to reduced renal clearance.
Hepatic metabolism via hydrolysis and conjugation; not significantly metabolized by CYP enzymes.
Hepatic via glucuronidation; substrate of P-glycoprotein; renal excretion of unchanged drug.
Renal (≈70% as unchanged drug), biliary/fecal (≈30%)
Renal excretion of unchanged drug accounts for 60-80% of elimination; nonrenal clearance is 20-40% (biliary/fecal).
25–30% bound to albumin.
20-30% bound to plasma proteins, primarily albumin.

Oral: 70–85% (variable, dependent on gastrointestinal absorption).
Oral: 60-80% (Lanoxin Pediatric elixir 70-85%); variable due to first-pass metabolism and P-glycoprotein effects.
GFR <30 m L/min: reduce dose by 50% and extend dosing interval to every 12-24 hours. GFR 30-50 m L/min: consider 25% dose reduction. Monitor digoxin levels.

Initiate with 50% of usual adult dose due to reduced renal function and increased sensitivity. Maximum loading dose: 0.2 mg IV. Maintenance: 0.1 mg every 12 hours. Monitor electrolytes and ECG.
Reduced dose: initial maintenance 0.0625-0.125 mg once daily due to age-related renal impairment and increased sensitivity. Monitor renal function and serum digoxin levels.
None.
Digitalis toxicity can cause severe arrhythmias; monitoring of serum digoxin levels required.
Risk of digitalis toxicity; monitor renal function and electrolytes; caution in hypokalemia, hypomagnesemia, and hypercalcemia.
Risk of toxicity in renal impairment, electrolyte disturbances, and drug interactions; monitor digoxin levels and ECG.
Ventricular fibrillation,Hypersensitivity to cardiac glycosides,Digitalis toxicity
Hypersensitivity to digoxin, ventricular fibrillation, digitalis toxicity.
Avoid high-potassium foods (bananas, oranges, spinach) unless directed; hypokalemia increases toxicity. Take with food to reduce GI upset. Do not take with high-fiber meals as may reduce absorption.
Avoid concurrent ingestion of high-fiber foods, as they may reduce absorption. Separate dosing by at least 2 hours from meals rich in bran, oats, or other fiber. Maintain consistent dietary potassium intake; both low and high potassium can affect digoxin toxicity. Grapefruit juice may increase absorption; avoid excessive consumption.
Acylanid is a cardiac glycoside with limited data in pregnancy. First trimester: No specific malformations reported, but potential for fetal cardiac effects due to mechanism. Second and third trimesters: Maternal toxicity (arrhythmias, electrolyte disturbances) may cause fetal hypoxia or growth restriction. Avoid toxicity. Category C.
First trimester: No evidence of increased risk of major malformations. Second/third trimester: Potential for fetal bradycardia, cardiac arrhythmias, and intrauterine growth restriction due to transplacental transfer and maternal hemodynamic changes.
Acylanid is excreted into breast milk in low amounts (M/P ratio not established; estimated <1% of maternal dose). No adverse effects reported in nursing infants. Use with caution, monitor infant for bradycardia or arrhythmias.
Digoxin is excreted into breast milk with an M/P ratio of approximately 0.6–0.9. Levels are low (typically <1 ng/m L) and considered compatible with breastfeeding; however, monitor infant for signs of toxicity including bradycardia and feeding difficulties.
Increased volume of distribution and renal clearance in pregnancy may reduce serum levels; monitor drug levels and adjust dose to maintain therapeutic range (0.5-2 ng/m L). Start at lower doses if hypokalemia or preeclampsia present.
Due to increased volume of distribution and renal clearance in pregnancy, higher doses (up to 30–50% increase) may be required to maintain therapeutic serum levels. Monitor serum digoxin concentrations and titrate to therapeutic range (0.5–0.9 ng/m L in heart failure; 0.8–2.0 ng/m L for arrhythmias).
Acylanid (lanatoside C) is a digitalis glycoside with rapid onset (IV 10-30 min) and moderate duration; use in atrial fibrillation with rapid ventricular response, especially in acute settings. Monitor renal function due to renal elimination; toxicity risk increases with hypokalemia, hypomagnesemia, hypercalcemia. Adjust dose in renal impairment (Cr Cl <50 m L/min). Therapeutic drug monitoring: target serum level 0.5-2 ng/m L (drawn >6-8 hours post-dose).
Lanoxin Pediatric (digoxin) requires monitoring of renal function and serum electrolytes (especially potassium and magnesium) due to narrow therapeutic index. Check digoxin levels 6-8 hours after dose; therapeutic range 0.8-2.0 ng/m L. Avoid concurrent use with drugs that affect renal function or electrolyte balance.
Take exactly as prescribed; do not skip doses or double up. Missed dose: take if within 12 hours, otherwise skip.,Monitor for signs of toxicity: nausea, vomiting, diarrhea, visual disturbances (yellow-green halos, blurred vision), confusion, irregular heartbeat.,Avoid OTC medications without consulting prescriber, especially antacids, laxatives, and antiarrhythmics.,Keep regular appointments for blood tests (digoxin level, kidney function, electrolytes).,Report weight gain >2 lbs/day, swelling, shortness of breath, or palpitations.
Take exactly as prescribed at the same time each day. Do not double the dose if you miss one.,Do not stop taking without consulting your doctor. Sudden withdrawal may worsen heart condition.,Watch for signs of toxicity: nausea, vomiting, diarrhea, vision changes (blurring, yellow-green halos), confusion, irregular heartbeat.,Keep all appointments for blood tests to monitor levels and kidney function.,Contact your doctor before taking any new medications, including over-the-counter drugs and supplements.,Limit alcohol and avoid potassium-sparing diuretics unless prescribed. Maintain consistent dietary intake of potassium-rich foods.

LANOXIN PEDIATRIC is a Cardiac Glycoside that works by Inhibition of Na+/K+ ATPase leading to increased intracellular calcium and positive inotropy.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between ACYLANID and LANOXIN PEDIATRIC depend on the specific clinical indication. These are both Cardiac Glycoside agents and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
