Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It causes vasodilation and decreases systemic vascular resistance.
AMVAZ (amivantamab-vmjw) is a bispecific monoclonal antibody that targets the extracellular domains of epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition factor (MET). It inhibits ligand binding, receptor activation, and downstream signaling, leading to antibody-dependent cellular cytotoxicity and tumor cell death.

Terminal elimination half-life is 12-18 hours; prolonged in renal impairment (up to 30 hours) requiring dose adjustment.
Extensively metabolized in the liver via cytochrome P450 (CYP) enzymes, primarily CYP3A4 and CYP2C8, to inactive metabolites.
AMVAZ is a monoclonal antibody; it is degraded into small peptides and amino acids via general protein catabolism. No specific metabolic pathways or enzymes involved.
Primarily hepatic metabolism to inactive metabolites; <1% excreted unchanged in urine. Biliary/fecal excretion of metabolites accounts for approximately 60-70% of total elimination, with renal excretion of metabolites approximately 30-40%.
Primarily renal excretion of unchanged drug (60-70%) and metabolites (10-20%); biliary/fecal excretion accounts for 15-25%.
>95% bound to plasma proteins (primarily albumin and alpha-1-acid glycoprotein).
98% bound to albumin primarily, with minor binding to alpha-1-acid glycoprotein.
8.4 L/kg (0.084 L/kg for a 70 kg adult? Please check: typical Vd is 8.4 L/kg? Actually nicardipine Vd is about 8.4 L/kg, which is large, indicating extensive tissue distribution). Correct: Vd = 8.4 L/kg (range 0.6-8.4 L/kg? Standard value is ~8.4 L/kg).
0.2-0.3 L/kg, indicating minimal extravascular distribution and confinement to plasma volume.
Oral: 35% (extensive first-pass metabolism); intravenous: 100%.
Oral bioavailability is 85-95%; reduced to 60-70% when taken with high-fat meals.

Use caution in patients with coronary artery disease due to risk of increased angina or myocardial infarction,May cause hypotension, hepatic impairment, and elevated liver enzymes,May exacerbate congestive heart failure,Use with caution in patients with impaired renal function,Monitor blood pressure and heart rate during infusion
Infusion-related reactions (IRRs): premedicate and monitor during infusion; interrupt or discontinue if severe.,Interstitial lung disease (ILD)/pneumonitis: monitor for new or worsening respiratory symptoms; withhold or permanently discontinue.,Dermatologic adverse reactions (rash, dry skin, pruritus): manage with topical corticosteroids, emollients, and oral antihistamines; consider dose modification.,Ocular toxicity: monitor for keratitis, uveitis; refer to ophthalmology if symptoms develop.,Embryo-fetal toxicity: can cause fetal harm; advise effective contraception.

Grapefruit and grapefruit juice may increase nicardipine levels; avoid concurrent use. No other significant food interactions. Maintain a heart-healthy, low-sodium diet as recommended for hypertension management.
Avoid grapefruit and grapefruit juice as they inhibit CYP3A4 metabolism, increasing amiodarone levels and risk of toxicity. Limit alcohol consumption due to potential hepatotoxicity. High-fat meals may increase absorption; take consistently with or without food.
NICARDIPINE (CARDENE) is a calcium channel blocker. Animal studies (rats, rabbits) showed embryotoxicity, fetotoxicity, and teratogenicity at doses ≥10× human dose. In humans, no adequate controlled studies; first trimester: potential for teratogenic risk (class C). Second and third trimesters: may cause fetal hypoxia, metabolic acidosis, and hypotension due to maternal hypotension. Use only if benefit outweighs risk.
No human data available; in animal studies, no teratogenicity observed at clinically relevant doses. First trimester: data insufficient to assess risk. Second and third trimesters: no known fetal harm.
NICARDIPINE is excreted in human milk. M/P ratio not reported. Limited data suggest low concentrations; however, potential for adverse effects in infant. Caution advised; consider alternative if possible.
No data on excretion in human milk; M/P ratio unknown. Caution recommended; benefits of breastfeeding should be weighed against potential risk to infant.
No specific dose adjustment guidelines for pregnancy; however, increased clearance and volume of distribution in pregnancy may necessitate higher doses. Start with lowest effective dose; titrate carefully to avoid maternal hypotension and fetal distress.
No specific dose adjustments required in pregnancy; pharmacokinetic changes not well-characterized. Use lowest effective dose and monitor clinical response.
Cardene (nicardipine) IV infusion in D5W is a dihydropyridine calcium channel blocker used for short-term treatment of hypertension when oral therapy is not feasible. It is photosensitive; protect from light. Administer via central line due to peripheral vein irritation. Titrate based on blood pressure response; onset within minutes. Use with caution in patients with severe aortic stenosis, heart failure, or hepatic impairment. Avoid in patients with advanced aortic stenosis due to risk of reducing coronary perfusion.
AMVAZ (amiodarone) has a long half-life (up to 107 days) and can cause thyroid, pulmonary, hepatic, and skin toxicity. Monitor thyroid function (TSH, T3, T4), liver enzymes (ALT, AST), and perform baseline pulmonary function tests and chest X-ray. Corneal microdeposits are common and may cause visual halos; usually reversible. Administer loading dose to achieve therapeutic effect more quickly. Avoid use with grapefruit juice as it increases drug levels.
