Calcium channel blocker (dihydropyridine type) that inhibits the influx of calcium ions into vascular smooth muscle and cardiac muscle, leading to vasodilation and decreased myocardial contractility.
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.
FDA: Management of chronic stable angina (vasospastic and exertional), treatment of hypertension.
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.
Intravenous: 5 mg/hr initially, titrate by 2.5 mg/hr every 15 minutes based on response; usual maintenance 3-10 mg/hr.
Intravenous: 500 mg every 6 hours.
2-4 hours (terminal); prolonged in hepatic impairment; clinical context: requires continuous IV infusion for sustained effect
Terminal elimination half-life is 12-18 hours; prolonged in renal impairment (up to 30 hours) requiring dose adjustment.
Primarily hepatic via CYP3A4; undergoes extensive first-pass metabolism. Metabolites are inactive.
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: 55-60% as metabolites, <1% unchanged; biliary/fecal: 35-40%
Primarily renal excretion of unchanged drug (60-70%) and metabolites (10-20%); biliary/fecal excretion accounts for 15-25%.
>95% bound to albumin, alpha-1-acid glycoprotein, and lipoproteins
98% bound to albumin primarily, with minor binding to alpha-1-acid glycoprotein.
0.2-0.6 L/kg; suggests limited tissue distribution; higher in hepatic cirrhosis
0.2-0.3 L/kg, indicating minimal extravascular distribution and confinement to plasma volume.
IV: 100%; not available orally in this formulation
Oral bioavailability is 85-95%; reduced to 60-70% when taken with high-fat meals.
GFR < 30 m L/min: initial dose 2.5 mg/hr; titrate cautiously. No adjustment for GFR ≥ 30.

Safety and efficacy not established; no standard dosing recommendations.
10 mg/kg IV every 6 hours; maximum 500 mg per dose.
Start at lower end of dosing range (2.5-3 mg/hr); titrate slowly due to increased sensitivity.
Consider renal function; start at lower end of dosing range due to age-related decreased renal clearance.
None.
None
Hypotension and reflex tachycardia may occur, especially in patients on beta-blockers.,Use caution in patients with congestive heart failure or impaired ventricular function.,May cause worsening of angina on abrupt withdrawal.,Hepatic impairment may increase drug levels; dose adjustment may be needed.,Peripheral edema is common but not due to fluid retention.
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 component of the formulation.,Advanced aortic stenosis.
None
Avoid grapefruit and grapefruit juice as they may increase nicardipine levels. High fat meals can affect absorption, but since this is IV, dietary restrictions primarily relate to dextrose content for diabetics. No other significant food interactions.
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.
First trimester: No adequate human studies; animal studies show no teratogenic effects at therapeutic doses. Second and third trimesters: Potential for fetal hypoxia, hypotension, and growth restriction due to maternal hypotension; avoid use for tocolysis.
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; estimated infant dose <2% of maternal weight-adjusted dose. M/P ratio: 1.2. Caution advised; monitor infant for hypotension and cardiovascular effects.
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 required based on pharmacokinetic changes; use lowest effective dose; monitor for maternal hypotension and fetal effects.
No specific dose adjustments required in pregnancy; pharmacokinetic changes not well-characterized. Use lowest effective dose and monitor clinical response.
CARDENE (nicardipine) in 4.8% dextrose is a dihydropyridine calcium channel blocker used for IV treatment of hypertension. It is light-sensitive; protect from light. Titrate dose by 1-2 mg/hour increments every 5 minutes up to target blood pressure. Do not mix with sodium bicarbonate or lactated Ringer's. Use with caution in patients with coronary artery disease due to reflex tachycardia, and in hepatic impairment as metabolism is hepatic. May cause peripheral edema; monitor for worsening heart failure.
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.
This medication is given intravenously to lower blood pressure; you will be closely monitored.,Inform your healthcare provider if you have a history of heart disease, liver problems, or if you are pregnant or breastfeeding.,You may experience headache, dizziness, or flushing; report these if severe.,Avoid alcohol consumption while on this medication as it may increase side effects.,This solution contains dextrose; notify your doctor if you have diabetes or need to restrict sugar intake.
Take AMVAZ exactly as prescribed; do not stop without consulting your doctor.,Avoid grapefruit and grapefruit juice while taking this medication.,Report any new or worsening shortness of breath, cough, chest pain, or palpitations immediately.,Notify your doctor if you experience vision changes, yellowing of skin/eyes, dark urine, or unusual fatigue.,Use effective contraception during treatment and for at least 6 months after stopping.,Avoid excessive sun exposure; use sunscreen and protective clothing due to risk of skin discoloration and photosensitivity.,Do not take over-the-counter medications or herbal supplements without checking with your doctor.,Regular blood tests and eye exams are necessary while on this medication.
