What is the role of disintegrants in tablets?

To add flavor
To increase viscosity
To facilitate breakup after oral admin
To prevent microorganism growth

The correct answer is: To facilitate breakup after oral admin

Disintegrants are added to tablets to facilitate their breakup after oral administration. This is important because disintegration allows the tablet to release the medication for absorption in the digestive tract. The disintegrants work by helping the tablet to rapidly break apart into smaller particles when it comes into contact with fluids in the stomach or intestines. This aids in the effective absorption of the medication. Options A, B, and D are incorrect: A. Adding flavor to tablets is typically done using flavoring agents and not disintegrants. B. Increasing viscosity is generally achieved using viscosity-enhancing agents and not disintegrants. D. Preventing microorganism growth is typically addressed by using preservatives or antimicrobial agents, not disintegrants.
