Preparation of ligustrazine solid lipid nanoparticles by film-ultrasonic wave dissolving techniques

[Objective] To prepare the ligustrazine solid lipid nanoparticles and investigate its entrapment efficiency and drug loading. [Methods] The ligustrazine solid lipid nanoparticles were prepared by film ultrasonic wave dissolving techniques. The optimum formula was selected through orthogonal design test according to the entrapment efficiency. [Results] The optimizing technique was using ligustrazine (30 mg),stearic acid (300 mg),lecithin (300 mg),mannitol (30g/L,15 mL). [Conclusion] The preparation technology of ligustrazine solid lipid nanoparticles by film ultrasonic wave dissolving technique is feasible.
