Abstract: Mucoadhesive formulations have been demonstrated to result in efficient drug delivery systems with
advantages over existing systems such as increased local retention and sustained drug release via adhesiveness
to mucosal tissues. The controlled release of colon-targeted, orally administered drugs has recently attracted a
number of studies investigating mucoadhesive systems. Consequently, substantial designs, from mucoadhesive
cores to shells of particles, have been studied with promising applications. This review will provide an
overview of specific strategies for developing mucoadhesive systems for colon-targeted oral delivery with controlled
drug release, including mucoadhesive matrices, cross-linked mucoadhesive microparticles, coatings and
mucoadhesive nanoparticles. The understanding of the basic principle of these designs and advanced formulations
throughout will lead to the development of products with efficient drug delivery at the colon for therapies
for different diseases.
