Abstract
含有下列物质的药用组合物:i)基本为惰性的珠粒;其中所述珠粒为用ii)包被的;ii)为(-)-(2R-顺式)-4-[4-[4-[4-[[5-(2,4-二氟苯基)-四氢-5-(1H-1,2,4-三唑-1-基甲基)呋喃-3-基]甲氧基]苯基]-1-哌嗪基]苯基]-2,4-二氢-2-[(S)-1-乙基-2(S)-羟基丙基]-3H-1,2,4-三唑-3-酮抗真菌剂;iii)粘合剂,以使所述抗真菌化合物粘附于所述珠粒上。该组合物能使具有极低水溶性的抗真菌化合物在哺乳动物例如人体中提高其生物利用度。
Description
本发明的背景
本发明涉及增加或提高新三唑类抗真菌化合物的生物利用度的组合物。
国际专利公开号WO 95/17407(1995年6月29日公开)提出了一类新的四氢呋喃/三唑类抗真菌化合物。发现其中的一个特殊化合物(2R-顺式)-4-[4-[4-[4-[[5-(2,4-二氟苯基)-四氢-5-(1H-1,2,4-三唑-1-基甲基)呋喃-3-基]甲氧基]苯基]-1-哌嗪基]苯基]-2,4-二氢-2-[(S)-1-乙基-2(S)-羟基丙基]-3H-1,2,4-三唑-3-酮(“抗真菌化合物”)在悬浮液中对机会性真菌例如曲霉菌、假丝酵母菌、隐球酵母菌及其它的机会性真菌具有有效的抗真菌活性。然而,发现固体组合物例如粉末剂或颗粒剂的抗真菌活性和/或生物利用度降低,推测是由于该化合物在水中的溶解度极低的缘故。因此需要提供在药用组合物中能增加或提高抗真菌活性和/或生物利用度的该抗真菌化合物。
本发明的简述
本发明涉及含有下列物质的药用组合物:
和ⅲ)使所述抗真菌化合物粘附于所述珠粒上的粘合剂。
该药用组合物也可以含有其它的赋形剂例如ⅳ)表面活性剂,ⅴ)增塑剂,ⅵ)消泡剂和着色剂。该药用组合物也可以制成其它合适的释放体系或剂型,例如胶囊剂、片剂或复制珠粒。
也令人吃惊和出人意料地发现用适当的粘合剂对珠粒用抗真菌化合物进行包被可以增加或相当于悬浮液中的抗真菌化合物的生物利用度。由于已知的参考文献,例如Peter G.Welling(Pharmacokinetics,Processes and Mathematics,American Chemical Society,Washingtion DC,ACS Monograph 185,1986,第57页)提出溶液和悬浮液一般比胶囊剂或片剂产生更令人满意的生物利用度,所以这些结果实在令人吃惊和出乎意料。J.G.Naim(Remington’s Pharmaceutical Sciences,18版,1990,Mack Publishing Co.,第83章,第1519页)也提出由于药物在其溶解状态被吸收,因而常常发现口服剂型的吸收速率按下列顺序降低:水溶液>含水悬浮液>胶囊或片剂。
本发明具有可以提供在药用组合物中的抗真菌化合物的优点,该药用组合物可以方便地配制成固体或“干”释放体系或剂型,例如胶囊剂、片剂或具有有效抗真菌活性和/或生物利用度的松散珠粒。
