To evaluate the efficacy and the safety of concomitant use of Ezetimibe/Rosuvastatin combination tablets and Candesartan cilexetil/Amlodipine besylate combination tablets compared to each combination tablet alone in patients with essential hypertension (HTN) and hyperlipidemia.

To improve the ease of use of high blood pressure and hyperlipidemia to improve patient compliance and reduce the risk of cardiovascular disease.

And It is recommended to identify the need to develop a combination of Candesartan cilexetil/Amlodipine besylate combination tablets , and Ezetimibe/Rosuvastatin combination tablets.

3. Provided the signed informed consent form voluntarily after receiving explanation of the objectives, methods and effects of the study.
4. Medically sterile or agreed to use medically acceptable contraceptive method during the study.
