Cardene (nicardipine) is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle. It dilates peripheral arterioles, reducing systemic vascular resistance and blood pressure, and also has coronary vasodilatory effects.
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.
Hypertension (chronic stable angina is not an approved indication in the US; however, it is used off-label for short-term treatment of hypertension in hospitalized patients and for subarachnoid hemorrhage to prevent vasospasm.,Off-label: short-term management of hypertension in hospitalized patients, prevention of cerebral vasospasm after subarachnoid hemorrhage.
FDA-approved for the treatment of adult patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.
20-40 mg orally three times daily.
Intravenous: 500 mg every 6 hours.
1.5-2 hours (terminal); prolonged in hepatic impairment (up to 6-8 hours)
Terminal elimination half-life is 12-18 hours; prolonged in renal impairment (up to 30 hours) requiring dose adjustment.
Hepatic metabolism primarily via cytochrome P450 isoenzymes CYP3A4 and CYP2C8, with minor contributions from CYP2D6.
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.
Renal: 60% as metabolites, 10% unchanged; Fecal: 35%
Primarily renal excretion of unchanged drug (60-70%) and metabolites (10-20%); biliary/fecal excretion accounts for 15-25%.
>95% bound to albumin and alpha-1 acid glycoprotein
98% bound to albumin primarily, with minor binding to alpha-1-acid glycoprotein.
0.6-1.2 L/kg (large Vd due to extensive tissue binding)
0.2-0.3 L/kg, indicating minimal extravascular distribution and confinement to plasma volume.
Oral: 35-60% (first-pass metabolism; increased with hepatic disease)
Oral bioavailability is 85-95%; reduced to 60-70% when taken with high-fat meals.
For GFR < 30 m L/min: initiate at 20 mg orally twice daily.
Cr Cl 30-50 m L/min: 250 mg every 6 hours; Cr Cl 15-29 m L/min: 250 mg every 12 hours; Cr Cl <15 m L/min: 250 mg every 24 hours; hemodialysis: 250 mg after dialysis.
Child-Pugh class B or C: reduce dose by 50% and titrate slowly.
Child-Pugh A: no adjustment; Child-Pugh B: reduce dose by 25%; Child-Pugh C: reduce dose by 50%.
Not established; safety and efficacy not determined.
10 mg/kg IV every 6 hours; maximum 500 mg per dose.
Initiate at 20 mg orally twice daily; titrate cautiously.
Consider renal function; start at lower end of dosing range due to age-related decreased renal clearance.
No FDA black box warning.
None
Hypotension (especially in patients with ventricular dysfunction or those receiving beta-blockers), increased angina (rare, more common with dihydropyridines), peripheral edema, congestive heart failure (use caution in patients with severe left ventricular dysfunction), hepatic impairment (reduce dose), renal impairment (monitor blood pressure), abrupt discontinuation may cause angina exacerbation.
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.
Hypersensitivity to nicardipine or any dihydropyridine, advanced aortic stenosis (may reduce coronary perfusion), second- or third-degree AV block (unless paced), sick sinus syndrome (unless paced), cardiogenic shock, concomitant use with strong CYP3A4 inducers (e.g., rifampin) due to decreased efficacy.
None
Grapefruit and grapefruit juice increase nicardipine exposure and should be avoided. High-fat meals may reduce absorption; take consistently with or without food. Alcohol may enhance hypotensive effects.
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.
Cardene (nicardipine) is classified as FDA Pregnancy Category C. In animal studies, nicardipine was associated with embryotoxicity, fetotoxicity, and teratogenicity at high doses. There are no adequate and well-controlled studies in pregnant women. Use in the first trimester should be avoided if possible; in the second and third trimesters, potential benefits must outweigh risks, particularly due to possible maternal hypotension and fetal hypoxia.
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 breast milk. The M/P ratio is approximately 0.7. Limited data suggest that concentrations in breast milk are low relative to therapeutic doses, but the effects on the nursing infant are unknown. Caution is advised.
No data on excretion in human milk; M/P ratio unknown. Caution recommended; benefits of breastfeeding should be weighed against potential risk to infant.
Pregnancy may alter the pharmacokinetics of nicardipine due to increased plasma volume and altered hepatic metabolism. However, specific dose adjustment recommendations are not established. In hypertensive emergencies, intravenous nicardipine is often used at standard doses with careful titration to avoid maternal hypotension. Oral doses may require titration based on response, starting at 20 mg three times daily.
No specific dose adjustments required in pregnancy; pharmacokinetic changes not well-characterized. Use lowest effective dose and monitor clinical response.
CARDENE (nicardipine) is a dihydropyridine calcium channel blocker used intravenously for acute hypertension. Onset is rapid (1-2 minutes), making it ideal for hypertensive emergencies. It is metabolized hepatically; reduce dose in hepatic impairment. Does not cause reflex tachycardia as prominently as other dihydropyridines. Contraindicated in advanced aortic stenosis. Can be used for hypertension during pregnancy but with caution.
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.
