The evaluations assistance ensure the TDDS will properly and effectively deliver the drug with the skin as meant.
The doc critiques gastrointestinal physiology and variables influencing gastric emptying. It also evaluates different GRDDS strategies and delivers illustrations of commercial gastroretentive formulations.
