ABSTRACT:
Solid dosage form for the controlled release of flavoxate hydrochloride is described. The dosage form includes a matrix allowing gradual release of the flavoxate hydrochloride contained within it, a suitable binder which limits the dimensions of the finished solid dosage form, and an acidifying agent which ensures stability of the flavoxate hydrochloride with time and improves its release profile by making it independent of pH.
