20100047341 | COMBINED PREPARATION FOR THE TREATMENT OF CARDIOVASCULAR DISEASES BASED ON CHRONOTHERAPY THEORY - 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. | 02-25-2010 |
20110038931 | COMPOSITE PREPARATION - The present invention provides a combination preparation which comprises: a prior-release section comprising aspirin or a pharmaceutically acceptable salt thereof as a pharmacologically active component; and a delayed-release section comprising clopidogrel, an isomer thereof or a pharmaceutically acceptable salt thereof as a pharmacologically active component. The combination preparation of the present invention exhibits a far better effect in preventing platelet aggregation than does simultaneous oral therapy or treatment with the respective single preparations, and not only can it improve the patient's drug-taking compliance by administration once a day but it can also reduce the adverse reactions which follow long-term administration of aspirin. The combination preparation of the present invention is also advantageous in that it exhibits an outstanding effect in inhibiting blood platelet aggregation despite a reduction in the amount of aspirin ingested, and in that it converts clopidogrel resistance into susceptibility and prevents serious adverse reactions caused by clopidogrel resistance and in that it can be stored over the longer term since it is stable under common storage conditions. | 02-17-2011 |
20110123612 | PHARMACEUTICAL PREPARATION CONTAINING NON-DIHYDROPYRIDINE CALCIUM CHANNEL BLOCKER AND ANGIOTENSIN-2 RECEPTOR BLOCKER - The present invention provides a pharmaceutical formulation comprising an immediate-release compartment containing an angiotensin-2 receptor blocker (ARB) as a pharmacologically active ingredient and an extended-release compartment containing a non-dihydropyridine calcium channel blocker as a pharmacologically active ingredient. Since the disclosed formulation enables the release of the two ingredients at a different time, it reduces side effects and increases the effects of the drug more than the case of separately administering the ingredients each at the same time. In addition, the formulation maximizes the effects of drug at the time of day when the complication risk of cardiovascular system diseases is highest. | 05-26-2011 |
20120015032 | COMBINATION PREPARATION COMPRISING INHIBITOR OF HMG-COA REDUCTASE AND ASPIRIN AND METHOD FOR MANUFACTURING THE SAME - The present invention relates to a chronotherapeutically combined pharmaceutical formulation for preventing and treating cardiovascular diseases, which is based on the principle of administering a plurality of drugs at certain time intervals (chronotherapy). Specifically, the combined pharmaceutical formulation comprises a HMG-CoA reductase inhibitor, such as simvastatin, and aspirin. Because the combined pharmaceutical formulation was developed based on the principle of administering drugs at certain time intervals, so-called chronotherapy, it shows an excellent effect of preventing or treating cardiovascular disease compared to those of the individual administration and simultaneous administration of the single preparations. Also, it is a once-daily dosage form which increases the medication compliance of patients. Particularly, even though the content of aspirin in the combined pharmaceutical formulation is reduced, the platelet aggregation inhibitory effect of aspirin in the combined pharmaceutical formulation is equal to that of the amount of aspirin used in the prior art, while the aspirin in the combined pharmaceutical formulation shows a antihypertensive effect. In addition, the chronotherapeutically combined pharmaceutical formulation allows the two drugs, which interact with each other, to be stored for a long period of time, and the combined pharmaceutical formulation ensures the human body-safety and efficacy of the two drugs. | 01-19-2012 |
