Abstract:
Objective: To prepare and optimize the formulation of intranasal thermo-sensitive gel of Zhi Xiong San and to evaluate its in vitro release mechanism and nasal mucosa permeability. Methods: The formulations of poloxamer thermo-sensitive gel were optimized by a central composite design-response surface method and its in vitro release mechanism and nasal mucosa permeability were evaluated by Franz diffusion chambers. Results: The optimal formulation was Poloxamer 407 (P407) 20% and Poloxamer 188 (P188) 6.5%. Imperatorin was released from the thermo-sensitive gels approximately with a zero-order mechanism, while ferulic acid with a Higuchi model. The formulation demonstrated the enhancement of nasal mucosa permeability. Conclusion: The optimal formulation provides a basis for the development of new administration routes and dosage forms of Zhi Xiong San.
