Journal ArticleDOI
An in vivo investigation into the suitability of pH dependent polymers for colonic targeting
TL;DR: In this article, the effect of a pH-dependent polymer coating, Eudragit S, on its ability to protect a model drug and control its release from rapidly disintegrating tablets has been examined in vitro.
Journal ArticleDOI
An evaluation of pectin as a carrier for drug targeting to the colon
TL;DR: In vitro experiments demonstrated that high methoxy pectin (pectin USP), when applied as a compression coat, proved capable of protecting a core tablet during conditions mimicking mouth-to-colon transit and was susceptible to enzymatic attack.
Journal ArticleDOI
Studies on pectin formulations for colonic drug delivery
TL;DR: It is suggested that either a high methoxy pectin formulation or a low methoxypectin with a carefully controlled amount of calcium should maximise colonie specificity by providing optimal protection of a drug during its transit to the colon and a high susceptibility to enzymic attack.
