摘要:
The present invention relates to a metformin tablet with sustained release and a method for preparing the same, more particularly to an improved metformin tablet with sustained release prepared by manufacturing a composition comprising metformin, which is an active ingredient for treatment of insulin-independent diabetes, and a matrix capable of controlling release rate of metformin into a slug at a given pressure condition, forming a tablet core by dry granulation and then forming a coated film on it, which is slowly released into the body at a constant rate for 24 hours, thereby maintaining a constant blood concentration for 24 hours when administered once a day while offering bioequivalence comparable to that of conventional products, and a method for preparing the same.
摘要:
The present invention relates to a metformin extended release tablet, particularly to a metformin extended release tablet comprising metformin, which is effective in treating non-insulin dependent diabetes mellitus, as active ingredient, and a matrix in which hydrophilic polymers and hydrophobic materials are mixed at a specific proportion. The hydrophilic polymers enable controlling of the pore size of the gel layer formed by water swelling, thereby enabling primary control of drug release rate. And, the hydrophobic materials block the pores of the gel layer, thereby enabling secondary control of drug release rate. Therefore, the metformin extended release tablet of the present invention has better dissolution properties than conventional extended release tablets and, thus, enables extended drug release at constant rate even with less matrix. A constant blood level can be maintained with one administration a day and the tablet can be made smaller, which makes the administration easier and the production simpler.
摘要:
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.
摘要:
The present invention relates to a combined pharmaceutical formulation, which is such designed that the release of each ingredient may be controlled to a predetermined release rate by applying the principle of the so-called chronotherapy, where drugs are administered in such a way that the activities of the drugs are expressed at intervals. The formulation of the present invention comprises statin-based lipid-lowering agent and dihydropyridine-based calcium channel blocker that affects cytochrome P450 enzyme as active ingredients, and is such constituted that the release rates of the aforementioned ingredients are different, thus preventing antagonism and side effects, while maintaining the synergistic effect, which leads to the convenience in medication.
摘要:
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.
摘要:
Disclosed is an anticancer pharmaceutical composition comprising phenformin or a pharmaceutically acceptable salt thereof, and 2-deoxy-D-glucose as active ingredients. These ingredients act in synergy with each other, thus exhibiting more potent inhibitory activity against the growth of cancer cells, compared to individual ingredients. Also, the synergistic anticancer activity allows the individual drugs to be used in lower amounts, which leads to a reduction in the occurrence of adverse effects. In addition, the time-lag release or administration of the ingredients decreases blood lactic acid levels to significantly mitigate the adverse effect of lactic acidosis, as well as exerting high anticancer effects. Particularly, the pharmaceutical composition can be formulated to dosage forms effective for therapy, increasing the drug compliance of the subject.
