Cleviprex (clevidipine) is a dihydropyridine L-type calcium channel blocker with high vascular selectivity. It inhibits calcium influx into vascular smooth muscle cells, causing arterial vasodilation and reduced peripheral vascular resistance.
Amlodipine: Dihydropyridine calcium channel blocker that inhibits calcium ion influx across cardiac and vascular smooth muscle cell membranes, causing vasodilation and reduced peripheral vascular resistance. Atorvastatin: HMG-Co A reductase inhibitor that competitively inhibits the conversion of HMG-Co A to mevalonate, reducing cholesterol synthesis in the liver.

Usual starting dose is 5/10 mg orally once daily; titrate at intervals of 2-4 weeks based on blood pressure and LDL-C goals. Maximum daily dose: amlodipine 10 mg; atorvastatin 80 mg.
Terminal elimination half-life: 2.7 minutes (dihydropyridine ring reduction) and 15 minutes (ester hydrolysis); clinical context: rapid offset allows precise titration
Amlodipine: terminal half-life 30-50 h (enables once-daily dosing). Atorvastatin: terminal half-life ~14 h, but active metabolites (ortho- and para-hydroxy atorvastatin) have half-life 20-30 h; clinically, pharmacodynamic half-life (HMG-Co A reductase inhibition) is ~20-30 h.
Rapidly metabolized by esterases in the blood and extravascular tissues to an inactive carboxylic acid metabolite (H152/81). Not primarily dependent on hepatic CYP450 enzymes.
Amlodipine: Extensively metabolized in the liver via CYP3A4 to inactive metabolites. Atorvastatin: Metabolized in the liver primarily by CYP3A4 to active ortho- and para-hydroxylated metabolites.
Renal: 63–73% as metabolites, fecal: 7–10%, unchanged drug in urine: <1%
Amlodipine: 60% renal (metabolites), 20-25% biliary/fecal. Atorvastatin: 1% renal (unchanged), 90% biliary/fecal (≥70% as metabolites).
87–97% bound to plasma proteins (primarily albumin)

0.32 L/kg (approx. 22 L for 70 kg); indicates limited extravascular distribution
Amlodipine: Vd ~21 L/kg (large, indicating extensive tissue distribution). Atorvastatin: Vd ~6.2 L/kg (moderately large, suggesting distribution into tissues).
Intravenous: 100% (only route administered)
Oral: amlodipine 64-90%; atorvastatin ~14% (low due to first-pass metabolism); food reduces rate but not extent of absorption.
No dose adjustment required for renal impairment. Clevidipine is not removed by dialysis.
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 atorvastatin with caution; maximum atorvastatin dose is 20 mg daily. Amlodipine is not dialyzable.
Contraindicated in patients with severe hepatic impairment (Child-Pugh Class C). Use with caution in moderate impairment (Child-Pugh B); consider lower initial doses and titrate slowly.
Contraindicated in active liver disease or unexplained persistent elevations of serum transaminases. For Child-Pugh Class A or B hepatic impairment: atorvastatin dose should be reduced; maximum atorvastatin dose is 20 mg daily. Amlodipine clearance is decreased; initial amlodipine dose should be 2.5 mg daily. No data for Child-Pugh Class C; use contraindicated.
Safety and efficacy not established in pediatric patients. No FDA-approved dosing recommendations.
Not recommended for pediatric patients. Safety and efficacy in children <10 years have not been established. For patients 10-17 years with heterozygous familial hypercholesterolemia, atorvastatin monotherapy is used; CADUET is not indicated.

Elderly patients (≥65 years) may have increased sensitivity to amlodipine; start at the lower end of dosing range (2.5 mg amlodipine component). Atorvastatin dose adjustment not required based on age alone. Monitor for hypotension and other adverse effects.
None.
HMG-Co A reductase inhibitors (statins) can cause fetal harm; use in pregnant women is contraindicated. Caduet contains atorvastatin; therefore, it is contraindicated in pregnant women.
Use caution in patients with heart failure, as beta-blocker withdrawal may exacerbate angina; continue beta-blocker therapy.,Hypotension and reflex tachycardia may occur; monitor blood pressure and heart rate closely.,Can cause acute kidney injury or worsening of renal function in at-risk patients.,Lipid emulsion formulation; use caution in patients with severe hypertriglyceridemia or lipid metabolism disorders.,Contains soybean oil and egg lecithin; contraindicated in patients with allergies to soybeans or eggs.,Not recommended for use in pediatric patients due to lack of safety and efficacy data.
Myopathy/Rhabdomyolysis: Risk increased with higher doses, age >65, renal impairment, hypothyroidism, and concurrent use of CYP3A4 inhibitors or other drugs that cause myopathy.,Hepatic effects: Elevated liver enzymes; perform liver function tests before initiation and as clinically indicated.,Fetal toxicity: May cause fetal harm; advise females of reproductive age to use effective contraception.,Peripheral edema: More common with higher doses of amlodipine, especially in females.,Hypotension: In patients with severe aortic stenosis.
Hypersensitivity to clevidipine or any component of the formulation (including soybean oil or egg lecithin),Severe aortic stenosis (may reduce cardiac output and worsen symptoms),Patients with defective lipid metabolism (e.g., hyperlipoproteinemia, lipoid nephrosis, acute pancreatitis with hyperlipidemia)
Active liver disease or unexplained persistent elevations of hepatic transaminases,Pregnancy,Breastfeeding (due to potential for serious adverse reactions in nursing infants),Hypersensitivity to amlodipine, atorvastatin, or any component of the formulation
No specific food interactions; administer IV only. The lipid emulsion contains soybean oil and egg lecithin; contraindicated in patients with allergies to soy or eggs. No oral intake required.
Avoid grapefruit and grapefruit juice as they increase atorvastatin plasma concentrations and risk of adverse effects. No significant food interactions with amlodipine.
Cleviprex (clevidipine) is a calcium channel blocker. No adequate and well-controlled studies in pregnant women. In animal studies, no teratogenic effects were observed at clinically relevant doses. However, maternal toxicity at high doses led to fetal effects (reduced fetal weight, delayed ossification). First trimester: limited data; risk cannot be excluded. Second and third trimesters: may cause fetal acidosis, hypotension, and bradycardia due to maternal hypotension. Use only if potential benefit justifies potential risk.
FDA Pregnancy Category X. Amlodipine: No evidence of teratogenicity in animal studies, but limited human data; atorvastatin: contraindicated in pregnancy as HMG-Co A reductase inhibitors are associated with fetal abnormalities, including skeletal and CNS defects. First trimester: Atorvastatin is contraindicated; risk of congenital anomalies. Second/third trimester: Avoid exposure; potential for fetal toxicity. Effective contraception required for women of childbearing potential.
No data on presence in human milk or effects on breastfed infants. Clevidipine is highly protein-bound (>99%) and rapidly metabolized, suggesting minimal excretion into milk. However, caution is advised. M/P ratio: not determined.
Excreted in human milk: Amlodipine: present in low levels (M/P ratio approximately 1.0); atorvastatin: unknown. Due to potential for serious adverse reactions in nursing infants (e.g., skeletal muscle toxicity from statins), breastfeeding is contraindicated during therapy. Alternative agents preferred.
No specific dose adjustments studied in pregnancy. Pharmacokinetic changes in pregnancy (increased volume of distribution, altered metabolism) may affect clearance, but no data. Use lowest effective dose and shortest duration. Titrate to effect with caution, as pregnant patients may have increased sensitivity to hypotensive effects.
Contraindicated during pregnancy; therefore, no dosing adjustments recommended. Discontinue therapy immediately if pregnancy is suspected or confirmed. Pharmacokinetic changes during pregnancy may alter drug metabolism, but no dose adjustments are justified due to teratogenic risk.
CLEVIPREX (clevidipine) is an ultrashort-acting dihydropyridine calcium channel blocker for IV use in perioperative hypertension. Onset within 2-4 minutes, half-life ~1 minute. Titrate every 5-10 minutes; avoid in severe aortic stenosis, heart failure with reduced ejection fraction, and lipid disorders (formulated in lipid emulsion). Monitor for reflex tachycardia. Use aseptic technique; discard unused portion after 12 hours.
CADUET is a fixed-dose combination of amlodipine (a calcium channel blocker) and atorvastatin (a statin) used for hypertension and dyslipidemia. Avoid concomitant use with strong CYP3A4 inhibitors (e.g., clarithromycin, itraconazole) due to increased statin exposure and risk of myopathy. Monitor liver enzymes before and during therapy, and for muscle symptoms. Use with caution in patients with severe renal impairment. Avoid grapefruit juice as it increases atorvastatin levels.
