[Study on prescription of self-microemulsifying drug delivery system of mangiferin phospholipid complex].

ABSTRACT

OBJECTIVE: To study formulation of self-microemulsifying drug delivery system (SMEDDS) of mangiferin phospholipid complex and improve dissolution and bioavailability of mangiferin. METHODS: Ternary phase diagram was applied to optimize the prescription of self-microemulsifying drug delivery system of mangiferin phospholipid complex, and the best recipe was selected by comprehensive evaluation of the speed of microemulsifying, microemulsion size and electric potential. RESULTS: The optimum formulation of SMEDDS was composed of IPM-Cremphor EL35-labrasol = 2 4.8 3.2. CONCLUSION: Self-microemulsifying drug delivery system of mangiferin phospholipid complex can effectively improve the dissolution of Mangiferin.
