ABSTRACT
Objective To screen the preparation process of 3,4,3″-trihydroxy p-terphenyl nanosuspension. Methods The nanosuspension was prepared in combination with the nanoprecipitation and microfluidization method. Taken the particle size for indicator, we investigated the stirring speed and precipitation temperature in the nanoprecipitation process, the homogeneous stress and cycles in the microfluidic process through single factor experiment. In addition, by factorial design, the variety and dosage of stabilizers are investigated. Results The excellent preparation condition of the nanosuspension are as follows 0 ℃ for the precipitation temperature, 900 rpm for the stirring speed, 1600 bar for the microfluidization pressure and 12 times for cycles. The ingredient ratio for drug poloxamer 188 lecithin is 1 0.8 0.8. Conclusion Through optimizing the preparation technology, we have successfully prepared nanosuspension with lower size , which will lay a foundation for further study.
