哮喘治疗药物zileuton的缓释剂型

SkyePharmaPLC宣布与美国的私人公司Critical治疗公司(CTI)达成协议开发口服哮喘病和慢性阻塞性肺病(COPD)治疗药物zileuton的一个控释剂型。
Zileuton的速释制剂是每天服用4次,由雅培公司上市,商标名为ZyfloFilmtab。SkyePharma公司已经开发了一个该药的控释剂型,使用的是Geomatrix技术。雅培公司已经完成了该产品治疗哮喘的III期临床试验。

SkyePharma公司将与CTI公司合作,进一步开发该剂型,用于治疗中度到重度哮喘和COPD。一旦获得FDA批准,CTI将通过自己专业销售团队在美国上市该药。CTI将偿付SkyePharma的开发费用,而后者将获得zileuton的部分销售收入,SkyePharma将负责在法国生产该药。

Zileuton是一个口服5-脂加氧酶抑制剂,可以阻断白三烯形成。长期使用zileuton可以减少其他药物使用,如β受体阻断剂、口服或吸入激素,这些药物都有副作用。

美国FDA批准的ZyfloFilmtab标签中称zileuton不能用于急性哮喘发作治疗,处于肝病活动期的患者不能使用该药。在使用该药期间推荐进行肝功能监测。如果使用了Zyflo,茶碱的使用量可以减少50%,需要进行监测;使用普萘洛尔(propranolol)或华法令(warfarin)的患者也要接受监测,适当时候调整剂量。报告的唯一的与安慰剂组有显著性差异的不良反应为胃部不适,治疗组为8.2%,安慰剂组为2.9%。
