This doc gives an overview of transdermal drug delivery systems. It defines transdermal therapeutic systems as self-contained dosage varieties that deliver drugs with the pores and skin in a controlled price.
Techniques to style and design-controlled release formulations determined by diffusion, dissolution and ion Trade concepts. Physicochemical and Organic properties of drugs appropriate to controlled release formulations.
A phrase of caution: Although We've got just classified and defined the different types of drug delivery, to focus on different rules, it should be famous that for any offered dosage kind, a strict categorization can be much from easy.
