Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
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.
BAROS (burosumab) is a recombinant human monoclonal antibody that binds to and inhibits fibroblast growth factor 23 (FGF23). By neutralizing excess FGF23, it increases renal phosphate reabsorption and enhances production of 1,25-dihydroxyvitamin D, thereby correcting hypophosphatemia and improving bone mineralization.

CADUET (amlodipine/atorvastatin) is available as tablets of 2.5/10, 2.5/20, 2.5/40, 5/10, 5/20, 5/40, 5/80, 10/10, 10/20, 10/40, and 10/80 mg amlodipine/atorvastatin. Initial dose depends on current antihypertensive and lipid-lowering therapy. 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.
None established.
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.
Terminal elimination half-life is 12-15 hours in healthy adults; may be prolonged in renal impairment (up to 30 hours in severe cases).
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.
Metabolized via general protein catabolism; not metabolized by CYP450 enzymes.
Amlodipine: 60% renal (metabolites), 20-25% biliary/fecal. Atorvastatin: 1% renal (unchanged), 90% biliary/fecal (≥70% as metabolites).
Renal excretion of unchanged drug accounts for 80-90% of elimination; biliary/fecal excretion accounts for 5-10%.
Amlodipine: ~93% bound to plasma proteins. Atorvastatin: ≥98% bound to plasma proteins (mainly albumin).
85-90% bound to albumin.
Amlodipine: Vd ~21 L/kg (large, indicating extensive tissue distribution). Atorvastatin: Vd ~6.2 L/kg (moderately large, suggesting distribution into tissues).
0.3-0.5 L/kg, indicating distribution primarily into extracellular fluid.
Oral: amlodipine 64-90%; atorvastatin ~14% (low due to first-pass metabolism); food reduces rate but not extent of absorption.
Oral: 60-80% (first-pass metabolism reduces bioavailability).
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.
No data available.
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.
No data available.
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.
No data available.
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.
No data available.
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.
None
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.
Hyperphosphatemia and risk of nephrocalcinosis/nephrolithiasis: monitor serum phosphorus and renal function,Severe hypersensitivity reactions including anaphylaxis,Potential for injection site reactions,Risk of hyperphosphatemia in patients with severe renal impairment,May increase risk of infections; avoid live vaccines during treatment
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
Concomitant use with oral phosphate and active vitamin D analogs (e.g., calcitriol, phosphate supplements) except during initial titration or adjustment when hypophosphatemia is severe,Severe renal impairment or end-stage renal disease (e GFR <30 m L/min/1.73 m²),Known hypersensitivity to burosumab or any excipients
Avoid grapefruit and grapefruit juice as they increase atorvastatin plasma concentrations and risk of adverse effects. No significant food interactions with amlodipine.
High-fat meals (>30% of calories from fat) increase the incidence of gastrointestinal adverse effects such as oily spotting, flatus with discharge, and steatorrhea. Dietary fat intake should be distributed over three main meals. The drug is most effective when combined with a reduced-calorie, low-fat diet. Foods rich in fat-soluble vitamins (A, D, E, K) should be consumed with a multivitamin supplement taken at bedtime to prevent deficiency.
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.
BAROS is contraindicated in pregnancy due to teratogenicity. First trimester: high risk of cardiac, CNS, and skeletal defects. Second/third trimesters: risk of fetal growth restriction and oligohydramnios. Animal studies show dose-dependent embryotoxicity. Human data limited but indicates significant risk.
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.
Excreted in breast milk; M/P ratio = 1.2. Avoid breastfeeding due to potential for infant toxicity. If unavoidable, monitor infant for drowsiness and poor feeding.
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.
Increased clearance in pregnancy (by 30%) due to enhanced hepatic metabolism and renal blood flow. Dose must be increased by 25-50% in the second and third trimesters, guided by therapeutic drug monitoring.
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.
BAROS is a brand name for orlistat, a reversible inhibitor of gastric and pancreatic lipases. It reduces dietary fat absorption by approximately 30% at the therapeutic dose of 120 mg three times daily. Monitor for fat-soluble vitamin deficiencies (A, D, E, K) and consider supplementation. Advise patients to take a multivitamin containing these vitamins at bedtime, at least 2 hours after the last dose. BAROS can cause oily spotting, flatus with discharge, fecal urgency, and steatorrhea, especially if dietary fat intake exceeds 30% of total calories. Contraindicated in chronic malabsorption syndrome and cholestasis. Use with caution in patients with a history of hyperoxaluria or calcium oxalate kidney stones.
