Problems solved by technology

[0002] Solifenacin succinate tablet is a prescription drug for treating symptoms such as overactive bladder, urgency, urinary incontinence, frequent urination, etc. The active ingredient is solifenacin succinate, and the clinical dosage of solifenacin succinate is Smaller, and solifenacin succinate has poor fluidity and compressibility, and has strong aggregation. It is difficult to ensure the uniformity of content by direct compression method, and the mixture will adhere to the On the punch, it is difficult to ensure the active ingredient content and uniformity of the prepared solifenacin succinate tablets; in addition, solifenacin succinate is extremely sensitive to water. Nasin crystals will be transformed into amorphous state in large quantities, and solifenacin succinate in amorphous state is easily degraded to generate impurities with no therapeutic effect, which seriously affects the efficacy and safety of medication
