Nicardipine is a dihydropyridine calcium channel blocker that inhibits the transmembrane influx of calcium ions into vascular smooth muscle and cardiac muscle, causing vasodilation and reduced myocardial contractility.
Acetated Ringer's solution provides isotonic crystalloid fluid and electrolytes, with acetate as a bicarbonate precursor metabolized in the liver and peripheral tissues, buffering metabolic acidosis. It restores intravascular volume and corrects electrolyte imbalances.
Short-term treatment of hypertension when oral therapy is not feasible or desirable
Fluid and electrolyte replacement in hypovolemia and metabolic acidosis,Maintenance of fluid and electrolyte balance during surgery or trauma
Intravenous infusion of 5 mg/hour initially, titrated by 2.5 mg/hour every 15 minutes up to 15 mg/hour for acute hypertension. Typical infusion rate: 5-15 mg/hour.
Intravenous infusion; dosing based on patient's fluid and electrolyte needs. Typical adult dose: 500-1000 m L per hour as needed for volume replacement; adjust rate based on clinical response and serum electrolyte monitoring.
Terminal elimination half-life is approximately 2-4 hours in healthy adults; prolonged to about 7 hours in cirrhosis or hepatic impairment.
Not applicable as a fixed half-life; components distribute and equilibrate rapidly. For administered volume, intravascular half-life is 20-30 minutes due to redistribution to interstitial space. Electrolyte half-lives: sodium ~8-12 hours, chloride ~8-12 hours, potassium ~12-24 hours, calcium ~24-48 hours, magnesium ~24-48 hours.
Hepatic via CYP3A4 and CYP2C8
Acetate is metabolized via acetyl-Co A in the tricarboxylic acid cycle, yielding bicarbonate; primary sites include liver and skeletal muscle.
Primarily hepatic metabolism; <1% excreted unchanged in urine. Biliary/fecal excretion accounts for approximately 35% of metabolites.
Acetated Ringer's solution components are excreted primarily renally: water (100% via kidneys), sodium (90-95% renal, 5-10% sweat/feces), chloride (90-95% renal), acetate (metabolized to bicarbonate, then CO2 excreted via lungs; <5% renal), potassium (80-90% renal, 10-20% feces), calcium (98% renal reabsorption, <2% fecal), magnesium (70% renal, 30% fecal).
>95% bound primarily to albumin.
Calcium: ~40% bound to albumin; magnesium: ~30% bound to albumin; other components (sodium, potassium, chloride, acetate) have negligible protein binding (<5%).
0.6-1.5 L/kg; extensive tissue distribution with high affinity for vascular smooth muscle.
Not a single value for all components. Water distributes into total body water (0.6 L/kg), sodium and chloride primarily into extracellular fluid (0.2 L/kg), potassium into intracellular fluid (0.4 L/kg), calcium and magnesium into bone and cells (Vd ~0.5-0.8 L/kg).
Intravenous: 100%; Oral: approximately 35% due to extensive first-pass metabolism.
Intravenous: 100% (only route administered). Oral: not applicable; not administered orally.
No dosage adjustment required for mild to moderate renal impairment (Cr Cl >30 m L/min). For severe renal impairment (Cr Cl <30 m L/min), use with caution; no specific dose reduction recommended but monitor closely.
No specific GFR-based dose adjustment required; however, use with caution in renal impairment due to risk of fluid overload and electrolyte imbalances. Monitor serum potassium and renal function.
In Child-Pugh Class A or B, reduce initial infusion rate to 2.5 mg/hour and titrate slowly. Avoid use in Child-Pugh Class C due to significant accumulation.
No specific Child-Pugh dose adjustment; use with caution in severe hepatic impairment due to potential altered lactate metabolism. Monitor electrolytes and acid-base status.
For children ≥2 years: Initial intravenous infusion of 0.5-1 mcg/kg/minute, titrate by 0.5 mcg/kg/minute every 5-15 minutes to desired effect. Maximum: 5 mcg/kg/minute.
Weight-based dosing: 20-30 m L/kg as a bolus over 30-60 minutes for volume expansion; maintenance: adjust based on fluid deficit and ongoing losses. Maximum rate and volume vary by clinical condition.
Initiate at lower end of dosing range (2.5-5 mg/hour intravenous infusion) and titrate slowly due to increased sensitivity and potential for hypotension.
Consider reduced initial volume and slower infusion rate due to decreased cardiovascular reserve and higher risk of fluid overload. Monitor closely for signs of heart failure and electrolyte disturbances.
No FDA boxed warning.
Not available; no FDA boxed warning.
Use caution in patients with heart failure, hepatic impairment, renal impairment, or acute cardiovascular disease. May cause hypotension, tachycardia, and peripheral edema. Monitor blood pressure and heart rate during infusion. Avoid abrupt discontinuation. Use with caution in patients with coronary artery disease due to possible reflex tachycardia.
Monitor serum electrolytes and acid-base status; avoid in patients with severe renal impairment or alkalosis; caution in heart failure, pulmonary edema, and conditions causing sodium retention.
Hypersensitivity to nicardipine or any component,Advanced aortic stenosis,Patients with known hypersensitivity to dihydropyridine calcium channel blockers
Hypernatremia, hyperkalemia, hypercalcemia, metabolic alkalosis, severe renal failure with oliguria/anuria, and known hypersensitivity to any component.
Grapefruit products (fruit and juice) should be avoided as they inhibit CYP3A4 metabolism of nicardipine, increasing its serum concentration and risk of hypotension and other adverse effects. No other significant food interactions known.
No specific food interactions. However, dietary intake of sodium and potassium should be considered in patients with electrolyte imbalances or renal impairment.
NICARDIPINE (CARDENE) - Teratogenic risk profile: First trimester: Limited human data; animal studies show no teratogenicity at clinically relevant doses. Second and third trimesters: No increased risk of major malformations reported; potential for maternal hypotension and fetal hypoxia with high doses. Avoid use in pregnancy-induced hypertension unless benefit outweighs risk.
No fetal risks identified; acetated Ringer's solution is isotonic and used for fluid and electrolyte replenishment. No teratogenic effects reported in any trimester.
NICARDIPINE (CARDENE) - Lactation summary: Excreted into breast milk in low concentrations (M/P ratio approximately 0.7); no adverse effects reported in infants. Use with caution, especially in preterm infants due to immature hepatic metabolism.
Considered safe during breastfeeding; components (sodium, chloride, potassium, calcium, acetate) are normal physiological constituents. M/P ratio not applicable.
NICARDIPINE (CARDENE) - Dosing adjustments in pregnancy: Pregnancy increases volume of distribution and clearance; dose requirements may be higher. Start at low end of dosing range and titrate to effect, monitoring for hypotension. Intravenous infusion: 5 mg/hour initially, increased by 2.5 mg/hour every 5-15 minutes to a maximum of 15 mg/hour.
No dose adjustments required due to pregnancy; pharmacokinetics of electrolytes and water unchanged; adjust dosing based on clinical status and losses.
Cardene (nicardipine) IV is a dihydropyridine calcium channel blocker used for short-term treatment of hypertension when oral therapy is not feasible. It has rapid onset and is titratable. Monitor for hypotension, reflex tachycardia, and peripheral edema. Use with caution in patients with aortic stenosis, coronary artery disease, or heart failure. It is compatible with 0.83% sodium chloride; avoid adding other drugs. Protect from light. Titrate based on blood pressure response. Hypotension may be profound in volume-depleted patients.
Acetated Ringer's is an isotonic crystalloid containing acetate as a bicarbonate precursor; it does not require hepatic metabolism for alkalinization, unlike lactate, making it preferable in patients with hepatic impairment or lactic acidosis. Monitor serum electrolytes and acid-base status during infusion, especially in renal impairment. Do not administer through same IV line with blood products due to risk of hemolysis from calcium content. Avoid use in metabolic alkalosis.
