摘要： A matrix type sustained-release preparation and a manufacturing method therefor are provided wherein dissolution with low pH dependence of a basic drug or a salt thereof at the early stage of dissolution can be ensured in a dissolution test, and wherein as the dissolution test proceeds, a ratio of a dissolution rate of the basic drug or the salt thereof in an acidic test solution to a dissolution rate of the basic drug or the salt thereof in a neutral test solution (dissolution rate in the acidic test solution/dissolution rate in the neutral test solution) decreases with dissolution time at the late stage of dissolution, as compared to the early stage of dissolution. According to the present invention, the matrix type sustained-release preparation contains a basic drug or a salt thereof and at least one enteric polymer, in which solubility of the basic drug or the salt thereof in a 0.1 N hydrochloric acid solution and a neutral aqueous solution, pH 6.0 is higher than in a basic aqueous solution, pH 8.0.
