Mucoadhesive Pellets for Drug Delivery Applications: A Critical Review
Pellets are spherical shaped multiparticulate drug delivery systems with size ranging between 0.5-2.0 mm. Free flow, good mechanical properties, improved physical and chemical properties of powder, and stability are some advantages of pellets. Mucoadhesive pellets could be developed
by using appropriate concentration and type of mucoadhesive polymer. Mucoadhesive pellets can be used for delivery of drugs to gastric, colonic, and vaginal regions. Immediate release, sustained/controlled release and implantable delivery could be incorporated using mucoadhesive pellets. Reproducibility,
ease of scalability, quality control checks and significant mechanical strength are some advantages making pellets widely acceptable by pharmaceutical industry. In the present review, mucoadhesion process and theories, mucoadhesive polymers, pelletization process, evaluation of pellets and
reported research/patents on mucoadhesive pellets for delivery of different categories of drugs have been presented.
期刊介绍：
With the explosion of research activity and reports, the need for concise and critical reviews of topics of contemporary research interest is manifest. Reviews of Adhesion and Adhesives (RAA) provides in-depth, incisive, illuminating and thought-provoking reviews written by subject matter experts covering all aspects of adhesion science and adhesive technology. Each review will be imbued with the author’s experience so that the reader will be able to assimilate the research in the area discussed easily and will be able to apply it in practice.The journal has relevance to a myriad of industries including textiles, printing, coatings, aerospace, medical, nanotechnology, biotechnology, building and construction, and microelectronics. The topics to be covered include, but not limited to, basic and theoretical aspects of adhesion; modeling of adhesion phenomena; mecha¬nisms of adhesion; surface and interfacial analysis and characterization; unraveling of events at interfaces; characterization of interphases; adhesion of thin films and coatings; adhesion aspects in reinforced composites; formation, characterization and durability of adhesive joints; surface preparation methods; polymer surface modification; biological adhesion; particle adhesion; adhesion of metallized plastics; adhesion of diamond-like films; adhesion pro¬moters; contact angle, wettability· and adhesion; superhydrophobicity and superhydrophilicity. With regard to adhesives, RAA will include, but not limited to, green adhesives; novel and high-performance adhesives; and medical adhesive applications.
