Excellent mucoadhesive polymers rapidly adhere to mucosal layers with out interfering with drug release, are biodegradable and non-toxic, and greatly enhance drug penetration at delivery web pages. The mechanisms of bioadhesion require wetting, swelling, interpenetration and entanglement of polymer chains followed by secondary bonding formations. Essential components influencing bioadhesion are discussed.
Floating systems contain non-effervescent and effervescent styles that float because of reduced density or gasoline generation. High-density systems never float but stay in the abdomen as a result of bioadhesion, magnetic forces, swelling to a substantial measurement, or raft development on gastric fluids.
Zero-Order Release is commonly employed for drugs which has a slender therapeutic window wherever precise dosing is essential.
Controlled drug delivery is one which provides the drug at a predetermined amount, for locally or systemically, for just a specified stretch of time. Continuous oral delivery read more of drugs at predictable and reproducible kinetics for predetermined period of time throughout the program of GIT.
