Objective: To investigate rapid dissolution mechanism of α-asarone by liquisolid compacts. Method: α-Asarone liquisolid tablets were prepared with solid-liquid ratio of 1:4
tween-80 as liquid excipient
microcrystalline cellulose PH-101 as carrier material
aerosil®200 as coating material.Dissolution of these liquisolid tablets and common tablets was compared
rapid release mechanism of these liquisolid tablets was investigated by measuring X-ray diffraction (XRD) and disintegration time. Result: Dissolution of α-asarone in liquisolid tablets was more than 80% in 5 min.XRD showed that there was no characteristic peaks of α-asarone in liquisolid tablets. Conclusion: Liquisolid compacts could improve drugs wetting properties and increase effective surface area of drugs dissolution
then allowing rapid dissolution of poorly soluble drugs.
