.0.5-5% Mineral salts……………………………1% No cost proteins…………………………..0.five-1% The system dependable during the formation of mucoadhesive bond Phase one : Wetting and swelling of your polymer(Get in touch with stage) Action 2 : Interpenetration involving the polymer chains and the mucosal membrane Move 3 : Development of bonds among the entangled chains (each often known as consolidation stage) Digital concept Wetting principle Adsorption idea Diffusion concept Fracture idea Rewards in excess of other controlled oral controlled release systems by advantage of prolongation of residence of drug in GIT. Concentrating on & localization of your dosage kind at a particular web site -Pain-free administration. -Very low enzymatic exercise & keep away from of first go metabolism If MDDS are adhere as well tightlgy since it is undesirable to exert an excessive amount of drive to get rid of the formulation right after use,if not the mucosa could be wounded. -Some client suffers unpleasent feeling. -Sad to say ,The dearth of standardized approaches frequently contributes to unclear success. -highly-priced drug delivery system
