How do you make mucoadhesive tablets?
Preparation of mucoadhesive tablets
Mucoadhesive tablets were prepared by conventional wet granulation. The powder mix was granulated with 5% w/w PVP‐K30 in isopropyl alcohol. The wet mass was passed through sieve # 16 and the granules were dried at 60°C for 1 hrs in a hot air oven.

Diffusion Theory of Mucoadhesion
Diffusion theory describes that polymeric chains from the bioadhesive interpenetrate into glycoprotein mucin chains and reach a sufficient depth within the opposite matrix to allow formation of a semipermanent bond.

What is mucoadhesive tablet?
Abstract. Oral mucoadhesive tablets belong to modern dosage forms, which allow controlled drug release after buccal application. They are used for the treatment of oral cavity disorders or for systemic administration of drugs with high first-pass effect or drugs instable in gastrointestinal tract.
Is mucoadhesive and bioadhesive same?
Leung and Robinson[3] described mucoadhesion as the interaction between a mucin surface and a synthetic or natural polymer. Mucoadhesion should not be confused with bioadhesion; in bioadhesion, the polymer is attached to the biological membrane and if the substrate is mucus membrane the term mucoadhesion is used.
What are the stages in mucoadhesion?
The mechanism by which mucoadhesion takes place has been said to have two stages, the contact (wetting) stage followed by the consolidation stage (the establishment of the adhesive interactions). The relative importance of each stage will depend on the individual application.
