Abstract: Disclosed herein is a lag time delayed-release combination pharmaceutical composition comprising of an angiotensin-II-receptor blocker and an HMG-CoA reductase inhibitor, as well as a preparation method thereof. The composition is designed based on chronotherapy in which active ingredients are administered to have different onset times, such that the release of each active ingredient of the composition in body can be lag time delayed to a specific rate. Also, the composition is very effective for the treatment of hypertension and the prevention of complications in patients having metabolic syndromes which show diabetes, obesity, hyperlipidemia, coronary artery diseases and the like. More specifically, the composition is a drug delivery system designed such that the release of each drug is controlled to a specific rate, and it can show the most ideal effect, when it is absorbed in body.

Abstract: The present invention relates to a functional combination preparation comprising a dihydropyridine-based calcium channel blocker such as amlodipine and an ARB (Angiotensin-2 receptor blocker) such as losartan. In particular, the present invention relates to a chronotherapeutical combination pharmaceutical formulations with controlled-release for the prevention or treatment of cardiovascular disease, which is formulated in accordance with xenobiotics and chronotherapy for enabling the two drugs to be chronotherapeutically released, thereby improving the therapeutic activity as compared to the co-administration of each drug in the form of a single pill, while reducing side effects and maintaining the therapeutic activity as high as possible at the time of day when the risk of a complication of cardiovascular disease is highest.

Abstract: The present invention relates to a chronotherapeutic combination pharmaceutical formulation, which is designed to control the release of each ingredient of the combined drug in a predetermined rate based on the principle of the so-called chronotherapy and xenobiotics, where drugs are administered to exhibit pharmacological activities at predetermined time intervals. The formulations of the present invention comprise a dihydropyridine, and a statin, as active ingredients. The formulations are structured and arranged such that the respective release rates of the above ingredients can be controlled, thereby reducing or preventing antagonistic effects and side effects resulting from the interaction of the above ingredients, while maintaining the synergistic effect, and providing easy medication.
