药理作用:泊沙康唑(posaconazole)是由伊曲康唑衍生而来。目前正在进行Ⅲ期临床试验。药理作用同唑类药物,但与伊曲康唑相比,其抑制固醇C14脱甲基作用更强,尤其对曲霉。
临床适应证及用法:临床上可用于曲霉病、接合菌病及镰刀菌病的治疗,亦可用于部分氟康唑耐药的念珠菌属感染的治疗。研究表明,泊沙康唑能广泛有效地治疗暗色丝孢霉病,提高皮炎外瓶霉感染者的生存率,作用呈剂量依赖性。该药作为二线用药,对两性霉素B或伊曲康唑耐药的侵袭性曲霉病的有效率为44%~78%,对接合菌感染的有效率为71%。该药为口服混悬剂,推荐剂量为200mg,每日4次,随餐口服7~10天,以后可维持此剂量,也可改为400mg,每日2次口服。7~10天内可获得稳态血药浓度。
