摘    要:为增加难溶性药物妥曲珠利的溶出度,加速药物在体内的溶解,吸收,提高妥曲珠利的生物利用度。以聚乙二醇6000为载体,加入助溶剂Z,采用了熔融法来制备妥曲珠利固体分散体,用正交设计方法优选制剂工艺,确定出最优处方为:妥曲珠利:PEG-6000:助溶剂Z=1:6:1.6(g/g)。妥曲珠利原料药在水中溶解度为4.12×10^-4g/L;妥曲珠利-PEG-6000(1:6)的溶解度为0.78g/L,体外溶出度达到88.75%。初步稳定性实验结果表明妥曲珠利固体分散物比较稳定,在水溶液中可以稳定存在,将妥曲珠利制备成固体分散剂可以很好的提高其溶出度。

关 键 词:妥曲珠利  固体分散物  溶出度  稳定性

Abstract:In order to increase the dissolution of toltrazuril, accelerate the dissolution and absorption of the drug in vivo and improve the bioavailability of tohrazuril. PEG - 6000 as the carrier, adding hydrotropy agent Z, using of the melting method to prepare toltrazuril solid dispersion. The orthogonal design was used for improvement of process, the optimal condition was: toltrazuril: PEG -6000: hydrotropy agent Z = 1: 6:1.6 (g/g). Tohrazuril in water was 4.12 × 10^-4 g/L, the solubility of tohrazuril - PEG -6000 ( 1:6 ) was 0. 078 g/L, and the toltrazuril solid dispersion' s dissolution in vitro was 88.75% , the result showed that toltrazuril solid dispersion was relatively stable and it could exist in water steadily. Toltrazuril solid dispersion can increase its dissolution .
Keywords:Toltrazuril  Solid dispersion  Dissolution  Stability
