Abstract

Objective: to prepare and evaluate orally disintegrating films of liquorice inclusion complexes. Methods: the active components of Chinese liquorice were extracted by pressurised extraction technique, and the inclusion complexes were prepared by antisolvent method, while the buccal disintegration films of liquorice inclusion complexes were prepared by solvent casting method, and the prepared buccal disintegration films were evaluated. Results: the home-made liquorice inclusion complexes orally disintegrated films formed better films, had good hardness and toughness, the thickness was around 0.1 mm and could disintegrate within 40 s, and the dissolution was rapid, the cumulative release reached 80.1% within 10 min, reaching the immediate release effect. Conclusion: the prepared buccal disintegrating membranes of liquorice inclusion complexes, which are expected to provide new ideas for the development and study of other drugs in the future, deserve further investigation.
