Stable angina, Angina Pectoris, Variant Amlodipine 5-10 mg orally once daily; most patients require 10 mg for adequate effect.

Coronary Artery Disease Amlodipine 5-10 mg orally once daily; majority of patients in clinical studies required 10 mg.

Hyperlipidemia, Hyperlipoproteinemia Type III, Hypertriglyceridemia, Diabetes Mellitus, Non-Insulin-Dependent, Coronary heart disease Atorvastatin 10-80 mg orally once daily; start at 40 mg if LDL-C reduction >45% is required.

Heterozygous familial hypercholesterolemia [HeFH] Atorvastatin 10-80 mg orally once daily in adults; 10-20 mg once daily in pediatric patients >=10 years.

Homozygous familial hypercholesterolemia [HoFH] Atorvastatin 10-80 mg orally once daily in adults and pediatric patients >=10 years; starting dose 10-20 mg once daily.

Diabetes Mellitus, Non-Insulin-Dependent Take once daily with a meal; recommended starting dose is 100 mg sitagliptin and 1000 mg metformin HCl extended-release once daily; maximum daily dose is 100 mg sitagliptin and 2000 mg metformin HCl; dose of sitagliptin component limited to 50 mg once daily if eGFR falls below 45 mL/min/1.73 m2; do not split, crush, or chew tablets.

Pharmacology

CADUET combines amlodipine, a dihydropyridine calcium channel blocker that inhibits transmembrane calcium influx into vascular smooth muscle and cardiac muscle to reduce peripheral vascular resistance and blood pressure, with atorvastatin, a selective, competitive HMG-CoA reductase inhibitor that lowers plasma cholesterol by reducing cholesterol synthesis in the liver and increasing hepatic LDL receptor expression.

JANUMET XR combines sitagliptin, a selective DPP-4 inhibitor that slows inactivation of incretin hormones (GLP-1 and GIP) to increase insulin release and decrease glucagon in a glucose-dependent manner, and metformin, a biguanide that decreases hepatic glucose production, reduces intestinal glucose absorption, and improves peripheral insulin sensitivity without altering insulin secretion.
