简介

部分中文托烷司琼处方资料(仅供参考)欧必亭Navoban中文别名:托烷司琼药品类别:止吐、催吐药及胃肠动力药化学成分:盐酸托烷司琼 tropisetron HCl药理药动:托烷司琼是一种外周神经元及中枢神经系统5-HT3受体的高效、高选择性竞争拮抗剂。某些常用癌症化疗药物可引起肠粘膜类嗜铬细胞释放出5 -羟色胺(5-HT),从而诱发伴恶心的呕吐反射。托烷司琼能选择性地阻断外周神经元突触前5-HT3受体的兴奋;在中枢神经系统内,本品对调节传入最后区的迷走神经活动的5-HT3受体可能有直接作用。本药的作用时限为24小时,故只需每天给药一次。本药的临床研究表明,在2-3个癌症化疗周期中连续使用本品也不会减低疗效。本药用于预防细胞毒药物引起的恶心和呕吐。临床研究表明不引起锥体外系副作用。

适应症:预防细胞毒药物引起的恶心和呕吐。

用法用量:在每一个治疗周期中,最多可以连续应用本品6天。成人 每日剂量为5 mg。建议在治疗的第1-6日静脉给药。2岁以上儿童 推荐剂量为200 μg/kg,最大剂量为5mg/日,最好静脉给药,疗程为6天,用法如成人。本药也可以作为口服液给药,应至少于早餐前1小时服用。如果单独使用本药反应不佳,可以通过同时应用地塞米松提高抗呕吐疗效,不需要增加剂量。肝、肾功能不全患者静脉给药时剂量应减半。高血压未控制的患者,用量不宜超过10 mg。

不良反应:临床研究中最常见的不良反应为,应用2 mg时的头痛(22%)和应用5mg时的便秘(11%)。这些反应在代谢不良者中的发生率更高。偶有关于头晕、疲劳和腹痛、腹泻等胃肠功能紊乱的报道(0.1-5%)。与其它5-HT3受体拮抗剂相似,个别病例出现虚脱、晕厥、心血管意外,但未明确本药与这些不良反应的关系,有可能是由于细胞毒药物或原有疾病所引起。与其它5 -HT3受体拮抗剂相似,有包括以下一种或多种表现的I型过敏反应的个别报道:面色潮红和/或全身荨麻疹,胸部压迫感,呼吸困难,急性支气管痉挛和低血压。

禁忌症:对托烷司琼或其它5-HT3受体拮抗剂(如恩丹西酮和格拉司琼)过敏者,以及孕妇禁用。

注意事项:对于金雀花碱/异喹胍代谢不良患者(约8%的白种人),虽然其清除半衰期与代谢正常者相比长4-5倍,应用本药的推荐剂量时未见药物引起的毒性副作用的报道,故不需减量。在急性肝炎或脂肪肝患者中,托烷司琼的药代动力学无改变,但肝硬化或肾功能损害患者与金雀花碱/异喹胍代谢正常的健康志愿者相比,血浆药物浓度高50%,因此,静脉给药时需降低剂量50%。因本药有引起血压进一步升高的危险,故高血压未控制的患者用量不宜超过10 mg。本药对驾车或操作机器的能力无影响,但应注意本药的不良反应有疲劳和头晕。

用药须知:化疗前,将1安瓿药物溶于100mL常用的输注液如生理盐水、林格氏液或5%葡萄糖液中,缓慢静脉滴注,不少于15分钟,或缓慢静脉注射(2mg/分,每安瓿约注射3分钟),也可缓慢加入已有滴注液中。口服本药时,可从安瓿中取所用量,用橙汁或可乐稀释后立即服用,至少在早餐前1小时服用。

药物相互作用:托烷司琼胶囊与食物同时摄入可能延缓吸收,绝对生物利用度有轻度增加(从约60%至约80%),但无相应的临床表现。与利福平或其它肝酶诱导药物(如苯巴比妥和保泰松)合用,可使托烷司琼的血浆浓度降低。细胞色素P450抑制剂如西米替丁对托烷司琼的血浆浓度影响极微,无需调整剂量。

药品过量:大剂量长期用药可导致幻视,并可使高血压患者的血压升高。出现用药过量时应对症治疗,应严密监测患者重要的生命体征。

贮藏:30°C以下贮存。
