Applications:
To assure the effectiveness of the medicine,tablets and capsules are required to disintegrate within a certain time,if different adding methods of the disintegrating agent are used,the different disintegrating and dissolution speeds will be achieved.PVPP is regarded as the top disintegrating agent thanks to its excellent swelling characteristics after the absoption of moisture.
