Many works have been reported so far on various drugs belonging to many categories like anihypetensives, anti-lipidemia, etc etc. But i want to know if any of the drugs have been marketed?
Dear Raja,
The attached publication cover some marketed oral hydrogel with sustained properties:
Hydrogels: from controlled release to
pH-responsive drug delivery

Hydrogels are one of the upcoming classes of polymer-based controlledrelease
drug delivery systems. Besides exhibiting swelling-controlled drug
release, hydrogels also show stimuli-responsive changes in their structural
network and hence, the drug release. Because of large variations in
physiological pH at various body sites in normal as well as pathological
conditions, pH-responsive polymeric networks have been extensively
studied. This review highlights the use of hydrogels (a class of polymeric
systems) in controlled drug delivery, and their application in stimuliresponsive,
especially pH-responsive, drug release
Hoping this will be helpful,
