Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Dihydropyridine calcium channel blocker; inhibits calcium ion influx across cardiac and vascular smooth muscle cells, reducing peripheral vascular resistance and blood pressure.
Digitalis glycoside; inhibits Na+/K+-ATPase, increasing intracellular calcium and cardiac contractility.
Hypertension,Chronic stable angina,Vasospastic angina (Prinzmetal's angina)
Heart failure,Atrial fibrillation,Atrial flutter
10-20 mg orally three times daily; extended-release: 30-60 mg orally once daily; maximum 120 mg/day.
0.05 to 0.2 mg intravenously or intramuscularly, administered slowly over 5 minutes; initial dose 0.15 to 0.2 mg, then 0.1 to 0.15 mg every 30 minutes up to a total of 0.4 mg. Oral: 0.05 to 0.2 mg daily for maintenance.
Terminal elimination half-life: 2-5 hours (immediate-release); 8-14 hours (extended-release). Context: shorter half-life necessitates multiple daily dosing for immediate-release; extended-release allows once-daily dosing.
Terminal elimination half-life is 36-48 hours in patients with normal renal function; prolonged to >100 hours in severe renal impairment, requiring dose adjustment.
Hepatic via CYP3A4; extensive first-pass metabolism; metabolites are inactive.
Hepatic (minor); primarily renally excreted unchanged.
Renal: 70-80% as metabolites; Fecal: 15-20% as metabolites; <1% unchanged in urine
Renal excretion of unchanged drug accounts for 60-70% of elimination; biliary/fecal excretion accounts for 30-40%, with enterohepatic circulation present.
92-98% bound to plasma proteins (albumin and alpha-1-acid glycoprotein)
25-30% bound to plasma albumin.
0.8-1.2 L/kg. Clinical meaning: indicates extensive tissue distribution, consistent with high lipophilicity.
6-10 L/kg; large Vd indicates extensive tissue distribution and high cardiac tissue affinity.
Oral immediate-release: 45-60% (due to first-pass metabolism); extended-release: 60-85% (due to slower release and reduced first-pass effect).
Oral: 70-80%; IV: 100%.
No dose adjustment required for GFR ≥30 m L/min; for GFR <30 m L/min, use with caution and reduce initial dose by 50%.
GFR <50 m L/min: reduce dose by 50% or extend dosing interval to every 36-48 hours. GFR <10 m L/min: avoid use or reduce dose by 75%.
Child-Pugh Class A: no adjustment; Class B: reduce dose by 50%; Class C: avoid use or reduce by 75%.
Child-Pugh Class A: no adjustment. Child-Pugh Class B: reduce dose by 25-50%. Child-Pugh Class C: avoid use or reduce dose by 75%.
0.25-0.5 mg/kg/dose orally every 6-8 hours; maximum 3 mg/kg/day. Extended-release not recommended.
Digitalizing dose: 0.01-0.02 mg/kg IV or IM, given in divided doses over 24 hours. Maintenance: 10-20% of digitalizing dose daily. Not recommended for neonates due to prolonged half-life.
Start at 10 mg orally twice daily; titrate slowly due to increased sensitivity and risk of hypotension.
Reduce dose by 25-50% due to decreased renal function and increased sensitivity. Monitor serum levels and renal function closely.
None
Can cause potentially fatal arrhythmias; use only when clearly indicated and monitor serum levels.
May cause hypotension, especially in patients on beta-blockers or with poor cardiac reserve,Risk of increased angina and/or myocardial infarction upon initiation or dose increase,Peripheral edema,Stevens-Johnson syndrome and toxic epidermal necrolysis (rare),Hepatic impairment,Exacerbation of angina on withdrawal
Narrow therapeutic index; toxicity risk increased with hypokalemia, hypomagnesemia, hypercalcemia, renal impairment; monitor ECG and drug levels.
Hypersensitivity to nifedipine,Cardiogenic shock,Significant aortic stenosis,Concurrent use with rifampin,Pregnancy (category C)
Ventricular fibrillation, digitalis toxicity, hypersensitivity, AV block (unless pacemaker present), Wolff-Parkinson-White syndrome.
Avoid grapefruit and grapefruit juice; they inhibit CYP3A4 and increase nifedipine serum concentrations, leading to enhanced hypotensive effects and risk of toxicity. Grapefruit interaction persists for 24 hours; separate consumption by at least 4 hours if unavoidable, but preferable to avoid entirely. Avoid alcohol which can increase hypotension. High-fat meals may reduce absorption of extended-release formulations; take consistently with or without food.
Avoid licorice, which can cause hypokalemia. Maintain consistent intake of potassium-rich foods (bananas, oranges) to avoid fluctuations. No known significant food interactions beyond electrolyte effects.
First trimester: Limited human data; animal studies show embryotoxicity. Second/third trimester: May cause fetal hypoxia due to maternal hypotension; risk of preterm labor inhibition. Category C.
Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk. Second/third trimester: Risk of fetal bradycardia, cardiac glycoside toxicity; avoids if possible.
Excreted in breast milk; M/P ratio ~0.85. Consider risks versus benefits; monitor infant for hypotension.
Deslanoside is excreted in breast milk; estimated infant dose 0.1-0.5% of maternal weight-adjusted dose; M/P ratio not well defined. Monitor infant for bradycardia, feeding difficulties; benefit likely outweighs risk.
No standard dose adjustment; monitor clinical response and blood pressure; may require lower doses due to vasodilation effects.
Increased renal clearance in pregnancy may require higher doses; monitor serum drug levels and adjust accordingly. Reduced dosing in third trimester may be needed due to volume expansion.
Adalat (nifedipine) is a dihydropyridine calcium channel blocker. Use immediate-release capsules only for hypertensive emergencies, not chronic treatment due to risk of reflex tachycardia and unpredictable hypotension. Extended-release formulations are preferred for stable angina and hypertension. Avoid grapefruit juice as it increases nifedipine levels via CYP3A4 inhibition. Monitor for peripheral edema, gingival hyperplasia, and constipation. Contraindicated in cardiogenic shock, severe aortic stenosis, and within 4 weeks of myocardial infarction.
Cedilanid-D (deslanoside) is a rapidly acting parenteral digitalis glycoside. Use with extreme caution in renal impairment due to reduced clearance. Monitor serum potassium and magnesium; hypokalemia and hypomagnesemia potentiate toxicity. Administer slow IV push over 5 minutes to avoid arrhythmias. Therapeutic drug monitoring less common due to short half-life of 33 hours. Contraindicated in ventricular tachycardia and AV block (unless due to atrial fibrillation).

Common clinical questions about ADALAT vs CEDILANID-D, answered by our medical review team.
ADALAT is a Calcium Channel Blocker that works by Dihydropyridine calcium channel blocker; inhibits calcium ion influx across cardiac and vascular smooth muscle cells, reducing peripheral vascular resistance and blood pressure.. CEDILANID-D is a Cardiac Glycoside that works by Digitalis glycoside; inhibits Na+/K+-ATPase, increasing intracellular calcium and cardiac contractility.. They differ in pharmacokinetic profiles, FDA-approved indications, and side effect profiles.
Potency comparisons between ADALAT and CEDILANID-D depend on the specific clinical indication. These are agents from distinct pharmacological classes and are not directly interchangeable by dose. A physician or clinical pharmacist should guide any therapeutic switching decisions.
The standard adult dose of ADALAT is: 10-20 mg orally three times daily; extended-release: 30-60 mg orally once daily; maximum 120 mg/day.. The standard adult dose of CEDILANID-D is: 0.05 to 0.2 mg intravenously or intramuscularly, administered slowly over 5 minutes; initial dose 0.15 to 0.2 mg, then 0.1 to 0.15 mg every 30 minutes up to a total of 0.4 mg. Oral: 0.05 to 0.2 mg daily for maintenance.. Dosing should always be individualized based on indication, renal and hepatic function, age, and other patient factors.
No direct drug-drug interaction has been formally documented between ADALAT and CEDILANID-D in current clinical databases. However, individual patient risk factors including other medications, organ function, and comorbidities should always be evaluated by a qualified healthcare provider.
The maternal-fetal safety profiles differ. ADALAT is classified as Category C. First trimester: Limited human data; animal studies show embryotoxicity. Second/third trimester: May cause fetal hypoxia due to maternal hypotension; risk of preterm labor inhibiti. CEDILANID-D is classified as Category C. Pregnancy Category C. First trimester: No adequate human studies; animal studies show fetal risk. Second/third trimester: Risk of fetal bradycardia, cardiac glycoside toxicity; avo. Always consult a maternal-fetal medicine specialist before taking either drug during pregnancy or lactation.
