Abstract:
A controlled-release preparation containing cilostazol is provided to improve absorption rate of cilostazol in small intestine and reduce side effects such as headache by staying in stomach for a long time and slowly releasing cilostazol, and enhance compliance of patient by reducing dosage frequency. A controlled-release preparation contains 10-80 wt.% of cilostazol or its pharmaceutically acceptable salt, 0.1-50 wt.% of solubilizer, 5-80 wt.% of swelling agent, 0.5-50 wt.% of swelling speed-controller and 0.1-50 wt.% of gas-generating material. A method for preparing the controlled-release preparation containing cilostazol comprises the steps of: mixing cilostazol or its pharmaceutically acceptable salt, solubilizer, swelling agent, swelling speed-controller and gas-generating material; granulating the mixture; and filling the granulates in capsules or tabletting the granulates.
Abstract:
PURPOSE: Provided is a controlled release preparation which minimizes the addition of a hydrophobic material, and prevents the surface adhesion of granules. The controlled release preparation continuously releases the drug content for 12 hours while maintaining the effective drug concentration in blood. CONSTITUTION: The controlled release preparation comprises 0.5-80wt.% of drug, 10-65wt.% of a hydrophobic release control additive, and 1-35wt.% of a hydrophobic wet granulating material. The drug is first melt-granulated using the hydrophobic release control additive, and the resulting granules are second wet-granulated using the hydrophobic wet granulating material.
Abstract:
