Abstract: The sustained release formulation for oral administration of an HMG-CoA reductase inhibitor of the present invention can be easily and economically prepared and is capable of maintaining a constant drug level in blood by slowly releasing the HMG-CoA reductase inhibitor at a uniform rate for 24 hrs. Accordingly, the sustained release formulation of the present invention can be effectively used for lowering blood cholesterol and triglyceride levels.

Abstract: Disclosed herein is a pharmaceutical composition comprising a part containing amlodipine or a pharmaceutically acceptable salt thereof and another separate part containing losartan or a pharmaceutically acceptable salt thereof, which exhibits improved preventive and therapeutic effects against cardiovascular disorders.

Abstract: A sustained-release composition for oral administration of a drug, comprising the drug, a mixture of sodium alginate and xanthan gum as a carrier for sustained release and a mixture of hydroxypropyl methylcellulose and propylene glycol alginate as a gel hydration accelerator, which is capable of maintaining a constant drug level in blood for 24 hours or more. Due to rapid gel hydration without forming a non-gelated core, the drug release rate follows zero order kinetics and does not significantly vary with the degree of gastrointestinal motility.

Abstract: A controlled release combination formulation for oral administration comprising a) a controlled release portion containing metformin or a pharmaceutically acceptable salt thereof as an active ingredient, and a combination of a polyethylene oxide and a natural gum as a carrier for controlled release; and b) a rapid-release portion containing a sulfonylurea-based medicine for treating diabetes as an active ingredient coated on the controlled release portion is useful for the treatment of diabetes, for it is capable of maintaining an effective concentration of the medicines in blood at a constant level.

Abstract: The present invention relates to a complex formulation for oral administration including amlodipine camsylate and simvastatin, and a preparation method thereof. The complex formulation of the present invention comprising amlodipine camsylate, simvastatin and a stabilizing agent can be used advantageously for preventing and treating diseases such as hyperlipidemia, atherosclerosis, hypertension, and cardiovascular disease.
