Chitosan is a biocompatible and biodegradable amino polysaccharide, which is soluble in aqueous solutions at pH < 6.5. It has been widely used for developing drug delivery systems because of its excellent mucoadhesive properties. Although many studies report on chitosan being mucoadhesive, the nature of interactions between chitosan and mucin remains ...

The adhesive properties of certain types of biopolymer can be used to increase the residence time of orally or nasally administered drugs. A fuller understanding of the molecular processes underpinning such ‘mucoadhesive’ phenomena will help in the optimal design of delivery systems.

Mucoadhesion and Characterization of Mucoadhesive Properties
2014Mucoadhesive dosage forms may improve both in vitro and in vivo performance of products due to their propensity to enhance the retention of the dosage form at the site of application. The appropriate and reliable characterization of mucoadhesive systems is crucial to enable the identification of the appropriate formulations for in vivo use.

Advances in Mucoadhesion and Mucoadhesive Polymers
Macromolecular Bioscience, 2010AbstractMucoadhesion is the ability of materials to adhere to mucosal membranes in the human body and provide a temporary retention. This property has been widely used to develop polymeric dosage forms for buccal, oral, nasal, ocular and vaginal drug delivery.

Mucoadhesive Drug Delivery Systems
2009The uptake of drugs is often limited by the short contact time between the formulation and the absorption membrane and by a fast washout. Using mucoadhesive polymers, however, the residence time of the dosage form on the mucosa can be significantly increased.

Mucoadhesive nanomedicines: characterization and modulation of mucoadhesion at the nanoscale
Expert Opinion on Drug Delivery, 2011The benefits of mucoadhesive systems are related to the increased in situ residence and intimate contact of the delivery vehicle with the mucosa. The recent emergence of nanomedicine and the properties of nanoparticulate systems have created new challenges in understanding the nature and mechanisms of nanoscale mucoadhesion and in the development of ...

Mucoadhesive Micropatterns for Enhanced Grip
2007 29th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2007The main challenge in designing diagnostic devices able to move along the colon is their locomotion method. Manipulating friction with the colonic surface is a key requirement for their safe and atraumatic propagation. One possible solution is to generate friction by means of adhesive forces.

Quantitative evaluation of mucoadhesive polymers to compare the mucoadhesion
Journal of Pharmaceutical Investigation, 2016Mucoadhesive drug delivery systems has received noticeable attentions in the pharmaceutical field, resulted in the adhesion of the drug to the tissue for a prolonged period of time. Three kinds of methods such as tensile strength test, mucin particle method and rheology were used to compare the quantitative mucoadhesion of mucoadhesive polymers ...

Drug Development and Industrial Pharmacy, 2007
The aim of this study was to characterize a buccal mucoadhesive film using lidocaine and its hydrochloride salt (LDHCL) as a model drug. Buccal films were developed using carbopol 971P as a mucoadhesive polymer, and glycerol as a plasticizer. Scanning Electron Microscope, Differential Scanning Calorimetry, X-ray powder diffraction, and Fourier ...

Mucoadhesion and the Gastrointestinal Tract
Critical Reviews in Therapeutic Drug Carrier Systems, 2008The concept of mucoadhesion is one that has the potential to improve the highly variable residence times experienced by drugs and dosage forms at various sites in the gastrointestinal tract, and consequently, to reduce variability and improve efficacy. Intimate contact with the mucosa should enhance absorption or improve topical therapy.
