Amlodipine/Atorvastatin: a review of its use in the treatment of hypertension and dyslipidaemia and the prevention of cardiovascular disease.

Amlodipine/atorvastatin (Caduet) is a single-tablet, fixed-dose combination of the dihydropyridine calcium channel antagonist amlodipine and the HMG-CoA reductase inhibitor atorvastatin. The bioavailability of amlodipine and atorvastatin with a single-tablet, fixed-dose amlodipine/atorvastatin combination was not significantly different to that with coadministered separate amlodipine and atorvastatin tablets. In well controlled clinical trials in patients with hypertension and dyslipidaemia, once-daily amlodipine and atorvastatin (administered as the single-tablet, fixed-dose combination or coadministered as two separate tablets) effectively reduced systolic BP (SBP) and low-density lipoprotein cholesterol (LDL-C) levels, and enabled more patients to achieve BP and LDL-C goals than single-agent or placebo therapy. There was no modification of the effect of amlodipine on SBP when administered in combination with atorvastatin and there was no modification of the effect of atorvastatin on LDL-C when administered in combination with amlodipine. In noncomparative, titration-to-goal, open-label 'real-world' trials, the single-tablet, fixed-dose combination of amlodipine/atorvastatin enabled patients with hypertension and dyslipidaemia to achieve both BP and LDL-C goals. Administration of a single tablet of amlodipine/atorvastatin, compared with coadministration of these agents as two separate tablets, improved patient adherence, according to a retrospective study that utilized prescription refill rates from a large US insurance database. Data from the large, randomized, double-blind, placebo-controlled ASCOT-LLA trial also demonstrated that the combination of amlodipine-based therapy and atorvastatin was effective in preventing cardiovascular (CV) endpoints in hypertensive patients at risk of CV disease (CVD). In summary, amlodipine/atorvastatin offers a convenient and effective approach to improving adherence and managing CV risk in hypertensive patients with dyslipidaemia or at risk of CVD.
