Gastroretentive drug delivery systems are also summarized, including floating drug delivery systems based on effervescence or hydrophilic polymers, substantial density systems, expandable systems, and bioadhesive systems. The mechanisms and illustrations of different gastroretentive technologies are presented in less than 3 sentences.
LiverLips 29 Nov 2011 WOW!!! What an incredible, indepth solution Rajive. Thank you ever so much for explaining the differences so really informatively. I will be sure to mark this a single to be a favorite as a way to return to it for upcoming viewings.
Beneficial to grasp the overview of mechanism of boosting the skin penetration with their examples.
Some important advantages of these routes include speedy onset of motion, avoidance of very first-pass metabolism, and enhanced bioavailability about oral delivery.
