简介

【药品名称】

商品名:Tarceva

通用名:盐酸厄洛替尼片

英文商品名:Tavceva

英文通用名:Erlotinib HCL Tablets

份子结构名:盐酸厄洛替尼片

【成份】每片内含150mg厄洛替尼(以盐酸厄洛替尼形式存在)

【作用机制】

Tarceva的抗肿瘤作用机制主要为抑制表皮生长因子(EGFR)酪氨酸激酶胞内磷酸化。

【药代动力学】

Tarceva口服后60%吸收,半衰期约36小时,主要由CYP3A4代谢清除。口服Tarceva150mg的生物利用度约60%,4小时后达血浆峰浓度。对591例接受单药Tarceva治疗的药代动力学分析显示,达到稳定血药浓度需7-8天,患者的年龄、体重、性别与药物的清除速率无显著关系,吸烟可使药物清除率增加24%。

【适应症】

Tarceva用于两个或两个以上化疗方案失败的局部晚期或转移的非小细胞肺癌的三线治疗。

【禁忌症】

对本品及成份过敏者禁用。

【不良反应】

最常见的不良反应是皮疹和腹泻,3/4度皮疹和腹泻的发生率分别为9%和6%,皮疹的中位出现时间是8天,腹泻中位出现时间为12天。

发生率大于10%的不良反应有:皮疹、腹泻、食欲减低、疲劳、呼吸困难、咳嗽、恶心、感染、呕吐、口腔炎、瘙痒、皮肤干燥、结膜炎、角膜结膜炎、腹痛。

【肺 毒 性】

有较少的报道提示在接受Tarceva治疗的NSCLC患者或其他实体瘤患者中可出现严重的间质性肺病(ILD),甚至导致死亡。在随机对照研究中,ILD的发生率是0.8%,并且这一发生率在Tarceva治疗组和安慰剂组是相同的。

报道的ILD包括:肺炎、间质性肺炎、间质性肺病、闭塞性细支气管炎、肺纤维化、急性呼吸应激综合征和肺渗出。症状发生于治疗后5天~超过9个月,中位发生时间为47天。多数患者常有混杂因素导致ILD发生,

如:之前有化疗/放疗、原有实质性肺疾病、肺转移或肺部感染。当有新出现的、难以解释的肺部症状,例如:呼吸困难、咳嗽、发热等,需进行检查评价,一旦诊断ILD,应停止继续使用Tarceva,并采取适当治疗。

【肝 毒 性】

Tarceva治疗可引起无症状的肝转氨酶升高,因此,治疗期间应定期复查肝功能,包括:转氨酶、胆红素、碱性磷酸酶等,如果肝功能损害严重应减量或停药。肝功能损害常为暂时性的或伴有肝转移。

较少报道有胃肠道出血,常发生于同时应用华法林的患者,所以,同时服用华法林或其他抗凝剂的患者应监测凝血酶原时间。

【老年患者】

安全性和药代动力学在年轻人和老年患者中无明显差异,因此,应用于老年患者时不建议调整剂量。

【注意事项】

本品必须在有此类药物使用经验的医生指导下使用,并仅在国家肿瘤药物临床试验基地或三级甲等医院使用。

【用法与用量】

本品必须在有此类药物使用经验的医生指导下使用,并仅在国家肿瘤药物临床试验基地或三级甲等医院使用。厄洛替尼单药用于非小细胞肺癌的推荐剂量为150mg/日,至少在进食前1小时或进食后2小时服用。持续用药直到疾病进展或出现不能耐受的毒性反应。无证据表明进展后继续治疗能使患者受益。

Indication and Usage for Lung Cancer PatientsTarceva monotherapy is indicated for the treatment of patients with locally advanced or metastatic non-small cell lung cancer after failure of at least one prior chemotherapy regimen.Results from two, multicenter, placebo-controlled, randomized, Phase 3 trials conducted in first-line patients with locally advanced or metastatic NSCLC showed no clinical benefit with the concurrent administration of Tarceva with platinum-based chemotherapy[carboplatin and paclitaxel or gemcitabine and cisplatin] and its use is not recommended in that setting.Indication and Usage for Pancreatic Cancer PatientsTarceva in combination with gemcitabine is indicated for the first-line treatment of patients with locally advanced, unresectable or metastatic pancreatic cancer.Important Information to KnowIn clinical studies, there were infrequent reports of serious lung injuries similar to Interstitial Lung Disease (ILD)-like events.Reports of ILD-like events have been serious and have included deaths in patients receiving Tarceva.Liver and/or kidney problems (including deaths) have been reported in some patients taking Tarceva. Let your doctor know if you have a history of liver or kidney disease.Patients receiving Tarceva plus gemcitabine were more likely to experience bleeding and clotting problems such as heart attack or stroke.Tarceva may cause harm to an unborn baby or may cause possible risk of pregnancy loss. Women should avoid becoming pregnant and avoid breastfeeding while taking Tarceva.You should call your doctor right away if you have these signs or symptoms: new or worsening skin rash; serious or ongoing diarrhea, nausea, loss of appetite, or vomiting; new or worsening shortness of breath or cough; fever; eye irritation.If you smoke, you should stop smoking while taking Tarceva, as it may affect how well Tarceva works for you.
