Mucoadhesive polymers play a critical role in controlled-release tablets for buccal drug
delivery.
Objective:
This research aimed to investigate the characterization and mechanisms of solid lipid particle-based tablets with different
mucoadhesive polymers for buccal delivery.
Methods:
Prednisolone (PSL)-loaded solid lipid particles (SLPs) were conventionally prepared by ultrasonication. The freeze-drying
method was used to convert the SLP suspension into a solid dosage form for buccal delivery by using mucoadhesive polymers.
Results:
All formulations showed over 80% drug release after 6 h, which followed immediate and sustained release patterns depending on
the SLP type. However, the different polymers in the formulations resulted in different mucoadhesion times and drug release and drug
permeability profiles. HPMC 4000 showed higher drug permeation (3327 μg vs. 2589 μg after 6 h) but a shorter mucoadhesion time than
Carbopol (197 min vs. 361 min). In addition, surface morphology, swelling and erosion, particle size and zeta potential were also noted for
the different mechanisms for buccal tablet design with different controlled release profiles.
Conclusion:
The results of this work indicate a good strategy for the selection of mucoadhesive polymers for SLP-based tablets in
improving the bioavailability of poorly water-soluble drugs.
