A randomized, placebo-controlled trial to evaluate the efficacy, safety, and pharmacodynamic interaction of coadministered amlodipine and atorvastatin in 1660 patients with concomitant hypertension and dyslipidemia: the respond trial.

Guidelines stress the importance of the simultaneous management of multiple cardiovascular risk factors. This can in part be achieved by coadministration of lipid-lowering and antihypertensive treatments. Potential pharmacodynamic interaction between drugs should be investigated as part of developing single-pill combinations.
