Abstract:
PROBLEM TO BE SOLVED: To provide a preparation in which absorbability of cilostazol commercially available as an antithrombotic drug, a cerebral circulation improving drug and the like is improved, particularly at the lower portion of the gastrointestinal tract. SOLUTION: A sustained release preparation of cilostazol having elution performance of cilostazol even at the lower part of the gastrointestinal tract is prepared by blending 1 pt.wt. of fine powder of cilostazol having an average particle size of not greater than 5 μm as an active ingredient with 0.005-50 pts.wt. of at least one surfactant selected from the group consisting of polyglycerol fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene castor oil, sucrose fatty acid ester, and alkyl sulfate salt.
