Preparation of Breviscapine Microemulsion for Parenteral Injection / 医药导报

ABSTRACT

Objective To study the prescription and preparation technology of breviscapine microemulsion for parenteral injection,and to evaluate its quality.Methods The prescription was selected and optimized through single-factor test and the pseudo-ternary phase diagram method.The preparation technology was investigated,and the particle diameter,drug content,encapsulation efficiency and haemolyticus were evaluated.Results The prescription composition of breviscapine microemulsion was soybean oilphospholipidHS15PEG400water=10.10.550.556.64 (m/m),with the drug content of 4.01 mg·mL-1,the acquired breviscapine microemulsion exhibited light yellow,uniform and transparent,with average particle diameter of 92.1 nm and encapsulation efficiency of 96.8%.The compatibility test showed no drug precipitation and the preparation was no hemolytic crisis.Conclusion The preparation of breviscapine microemulsion injection is correspond to the main index of parenteral injection.
