Gastroretentive drug delivery systems are summarized, which includes floating drug delivery systems based on effervescence or hydrophilic polymers, high density systems, expandable systems, and bioadhesive systems. The mechanisms and illustrations of various gastroretentive technologies are presented in a lot less than 3 sentences.

eight) Protection margins of higher potency drugs may be greater and also the incidence of both equally local and systemic adverse Uncomfortable side effects is often decreased in sensitive individuals.

This document discusses mucoadhesive drug delivery systems (MDDS). It commences by defining MDDS as systems that make use of the bioadhesive properties of certain polymers to target and lengthen the release of drugs at mucous membranes.

They may be meant to be both dispersed or dissolved in drinking water before consumption to supply really speedy pill dispersion and dissolution and release on the drug.
