    Abstract:
    The purpose of this study was to prepare and evaluate a taste-masked berberine hydrochloride orally disintegrating tablet for enhanced patient compliance. Taste masking was performed by coating berberine hydrochloride with Eudragit E100 using a fluidized bed. It was found that microcapsules with a drug-polymer ratio of 1:0.8 masked the bitter taste obviously. The microcapsules were formulated to orally disintegrating tablets and the optimized tablets containing 6% (w/w) crospovidone XL and 15% (w/w) microcrystalline cellulose showed the fastest disintegration, within 25.5 s, and had a pleasant taste. The dissolution profiles revealed that the taste-masked orally disintegrating tablets released the drug faster than commercial tablets in the first 10 min. However, their dissolution profiles were very similar after 10 min. The prepared taste-masked tablets remained stable after 6 months of storage. The pharmacokinetics of the taste-masked and commercial tablets was evaluated in rabbits. The Cmax, Tmax, and AUC0-24 values were not significantly different from each other, suggesting that the taste-masked orally disintegrating tablets are bioequivalent to commercial tablets in rabbits. These tablets will enhance patient compliance by masking taste and improve patients' quality of life.
