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 witll be achieved.PolyKoVidone is regarded as the top disintegrating agent thanks to its excellent swelling characteristics after the absoption of moisture.

Highly efficient disintegrating agent:Makes all excipients swell quickly,effective for wet & dry granulations and direct compression formulations,PolyKoVidone can be added before or after granulation.Its swelling action and disintegration time will be not impacted by wetting or drying.
Suspension stabilizer:PolyKoVidone acts as a hydrophilic polymer,increasing the viscosity,improving the dispersal capacity,reducing the sedimentation rate of drugs,meanwhile,increasing the redispersal capacity of the solution sediment,suitable for liquid prepara
