Disintegrants are substances that enable tablets to be rapidly cracked into fine particles in gastrointestinal fluids, thereby enabling the functional ingredients to be rapidly dissolved and absorbed and to function. Most of these substances have good water absorption and swelling properties, thus enabling the disintegration of tablets. Except for slow-release tablets and certain special-purpose tablets, disintegrating agents should be added to tablets in general. The disintegrating agent serves to remove the binding force due to the binder or high compression, thus disintegrating the tablet in water. The disintegration of tablets undergoes wetting, siphoning and breaking.
