The invention provides a kind of Nifedipine composition slow releasing capsule relate to medicine and medicine manufacture technology field by following component made: nifedipine 3.26%～7.27% chitosan nano 63.01%～85.01% magnesium stearate 3.26%～7.27% starch 3.26%～7.27%.Beneficial effect of the present invention is: chitosan nano is the microgranule that a kind of particle diameter is less than 100nm its positively charged can combination with chloride ion because of insoluble absorbability is not drained in external makes Blood pressure drop; Nifedipine and chitosan nano coupling can improve the bioavailability of nifedipine; This compositions can significantly strengthen the effect of the blood pressure lowering of nifedipine can reduce clinically the consumption of nifedipine reduces the untoward reaction of nifedipine.
