Abstract:
Mucoadhesive drug delivery systems interact with the mucus layer covering the mucosal epithelial surface, and mucin molecules and increase the residence time of the dosage form at the site of absorption. The drugs which have local action or those which have maximum absorption in gastrointestinal tract (GIT) require increased duration of stay in GIT. Thus, mucoadhesive dosage forms are advantageous in increasing the drug plasma concentrations and also therapeutic activity. In this regard, this review covers the areas of mechanisms and theories of mucoadhesion, factors influencing the mucoadhesive devices and also various mucoadhesive dosage forms.
Insights
Mucoadhesive drug delivery systems enhance drug absorption by increasing residence time at the absorption site. This review explores mucoadhesion mechanisms, influencing factors, and various dosage forms for improved therapeutic outcomes.
Area of Science:
- Pharmaceutics
- Biomaterials Science
Background:
- Mucoadhesive drug delivery systems interact with mucosal surfaces, prolonging drug contact time.
- Increased residence time is crucial for drugs requiring local action or enhanced absorption in the gastrointestinal tract (GIT).
Purpose of the Study:
- To review the fundamental mechanisms and theories behind mucoadhesion.
- To identify key factors influencing the performance of mucoadhesive devices.
- To provide an overview of various mucoadhesive dosage forms.
Main Methods:
- Literature review of scientific publications on mucoadhesion.
- Synthesis of information on mucoadhesion theories and influencing factors.
- Categorization and description of different mucoadhesive dosage forms.
Main Results:
- Mucoadhesion relies on interactions between dosage forms and mucin molecules.
- Factors such as contact time, surface area, and environmental conditions affect mucoadhesion.
- Various mucoadhesive systems, including gels, films, and nanoparticles, have been developed.
Conclusions:
- Mucoadhesive systems offer significant advantages for drug delivery, improving drug plasma concentrations and therapeutic efficacy.
- Understanding mucoadhesion mechanisms and influencing factors is key to designing effective mucoadhesive dosage forms.
- Further research into novel mucoadhesive materials and formulations can optimize drug delivery.
