MATRIX-TYPE SUSTAINED RELEASE PREPARATION CONTAINING BASIC ADDITIVE |
摘要 |
Disclosed is a matrix-type sustained release preparation containing a basic drug unstable against an acid as an active pharmaceutical ingredient, wherein the decomposition of the basic drug unstable against the acid can be prevented and therefore the pH-dependent release can be reduced. A hardly water-soluble basic normal salt is added to a matrix-type sustained release preparation containing a basic drug that is unstable against an acid.
