Abstract
A pharmaceutical composition having consistently a desirable release rate is prepared by controlling the finally mixing time based on the molecular weight measured in the intermediate product. The pharmaceutical composition includes micro particles containing a polyhydric alcohol, a salt, a water-soluble polymer and a pharmaceutically active ingredient. The micro particles are dispersed in a matrix of a hydrophobic ingredient and an amphipathic ingredient.
