罗氟司特获FDA批准将250 mcg作为初始剂量治疗慢性阻塞性肺病

2018-01-29 MedSci MedSci原创

罗氟司特为磷酸二酯酶- 4(PDE - 4)抑制剂,是新型慢性阻塞性肺病(COPD)治疗药物。罗氟司特目前被用于治疗严重COPD患者的支气管炎相关咳嗽和黏液过多等症状。该药物的所属公司阿斯利康近日宣布,美国FDA已经批准250 mcg的罗氟司特作为起始剂量,在治疗的前4周每天给药一次,其后以500 mcg的剂量每天给药一次来帮助降低患者的治疗中止率。 罗氟司特目前用于降低伴有慢性支气管炎并有加重病

罗氟司特为磷酸二酯酶- 4(PDE - 4)抑制剂,是新型慢性阻塞性肺病(COPD)治疗药物。罗氟司特目前被用于治疗严重COPD患者的支气管炎相关咳嗽和黏液过多等症状。该药物的所属公司阿斯利康近日宣布,美国FDA已经批准250 mcg的罗氟司特作为起始剂量,在治疗的前4周每天给药一次,其后以500 mcg的剂量每天给药一次来帮助降低患者的治疗中止率。 罗氟司特目前用于降低伴有慢性支气管炎并有加重病史的重度慢性阻塞性肺病(COPD)。值得注意的是,罗氟司特并不是支气管扩张剂,不能用于缓解急性支气管痉挛,同时250 mcg的罗氟司特是起始剂量,仅用于治疗的前4周,并不是有效治疗剂量。

结果显示,在12周的治疗期间,和罗氟司特500 mcg治疗12周组相比,起始接受罗氟司特250 mcg 治疗4周,其后500 mcg治疗8周组中患者的治疗中止率仅为18.4%,而前者的该数值为24.6%。最常见的不良反应分别是腹泻(500 mcg持续12周组与250 mcg初始剂量组对比,下同,9.5% vs 2.7%),体重减轻(7.5% vs 2.1%),恶心(4.7% vs 1.4%),头痛(4.1% vs 2.1%),腰痛(3.2% vs 2.2%),流感(2.8% vs 2.7%),失眠(2.4% vs 1.0%),头晕(2.1% vs 1.1%),食欲下降(2.1% vs 0.4%)。

因此以250 mcg作为初始剂量的罗氟司特治疗是安全有效的。
