Caduet's development originated from Pfizer's recognition that many patients with cardiovascular disease require treatment for multiple risk factors simultaneously, including both hypertension (high blood pressure) and dyslipidemia (abnormal blood lipid levels). Treating multiple cardiovascular risk factors requires patients to take multiple medications, which can reduce adherence and increase the complexity of medication management.

Pfizer had two of the world's leading cardiovascular medications in its portfolio: Norvasc (amlodipine besylate), a long-acting dihydropyridine calcium channel blocker approved for hypertension and coronary artery disease, and Lipitor (atorvastatin calcium), the world's best-selling statin and the best-selling drug of any class for many years. Both drugs had well-established efficacy and safety profiles and were among the most prescribed medications globally.

Amlodipine works by blocking L-type calcium channels in vascular smooth muscle and cardiac muscle cells, reducing the influx of calcium ions that triggers muscle contraction. This reduces peripheral vascular resistance and lowers blood pressure, and also reduces the oxygen demand of the heart, making it effective for both hypertension and coronary artery disease (angina). Amlodipine's long half-life (approximately 30 to 50 hours) allows once-daily dosing and provides smooth, sustained blood pressure control.

Atorvastatin works by competitively inhibiting HMG-CoA reductase, the rate-limiting enzyme in the cholesterol biosynthesis pathway. By reducing cholesterol synthesis in the liver, atorvastatin lowers LDL cholesterol levels and reduces the risk of cardiovascular events including myocardial infarction and stroke. Atorvastatin is the most potent of the commonly used statins and is effective at reducing LDL cholesterol across a wide range of doses.

Pfizer combined amlodipine and atorvastatin into a single tablet to create Caduet, which allows patients requiring both agents to take a single pill rather than two separate medications. The FDA approved Caduet on January 30, 2004, as the first dual-therapy product to be marketed for both hypertension and dyslipidemia and the first cross-risk-factor single-pill combination. Caduet was available in nine strength combinations (amlodipine 2.5, 5, or 10 mg combined with atorvastatin 10, 20, 40, or 80 mg), providing flexibility to tailor the dose of each component to the individual patient's needs.

Caduet's commercial success was built on the established patient populations for Norvasc and Lipitor, both of which had large numbers of patients who required both a calcium channel blocker and a statin. The single-pill formulation offered a convenience advantage that could improve medication adherence, a significant clinical benefit given that poor adherence to cardiovascular medications is associated with increased rates of cardiovascular events.

Lipitor's patent expired in November 2011, and generic atorvastatin became widely available. Norvasc's patent had expired earlier, and generic amlodipine was already widely available. The availability of inexpensive generic versions of both components significantly reduced the commercial rationale for branded Caduet, as patients and prescribers could achieve the same therapeutic effect by taking generic amlodipine and generic atorvastatin separately at substantially lower cost. Generic amlodipine/atorvastatin combination tablets subsequently became available, providing a generic alternative to branded Caduet.
