药物剂型
1.注射剂:100mg(5ml);
2.胶囊:50mg,100mg。
药理作用
本品是鬼臼毒素的半合成衍生物,属细胞周期特异性药物,作用于晚S期及G2期,其作用位点是拓扑异构酶Ⅱ,形成本品、酶和DNA三者间稳定的可裂性复合物,干扰DNA拓扑异构酶Ⅱ的功能,使DNA损伤后难以重新修复。由于本品与DNA拓扑异构酶Ⅱ的结合是可逆的,并作用于细胞周期中持续时间较长的S期、G2期,因此血药浓度持续时间长短比峰浓度更重要,且高峰浓度(>5~10μg/ml)与严重的骨髓抑制有关,故一般采用静脉滴注,而不用静脉推注。口服Vp-16软胶囊疗程长,可提高抗肿瘤活性。临床前研究表明,对多种实验动物肿瘤有抑制作用,如L1210、P388、S37、S180、黑色素瘤B16、小鼠Lewis肺癌、艾氏腹水癌等。VP-16抗瘤谱广,并与CTX、Ara-C、DDP、BCNU等多种抗肿瘤药物有协同作用。本药为鬼臼毒素的半合成衍生物依托泊苷的水溶性酯,为静脉注射用抗肿瘤药,因其良好的水溶性而降低了因稀释或静脉注射时发生沉淀的可能性。其作用机制与依托泊苷相同。单次剂量瓶装含有相当于依托泊苷100mg的磷酸依托泊苷无菌冻干制剂和枸橼酸钠32.7mg、右旋糖酐40.3g。
药动学
口服约50%被吸收,tmax为1~2h。口服生物利用度48%(25%~74%)。静脉注射后97%与血浆蛋白结合。主要分布在胆汁、腹水、尿、胸腔积液和肺组织,进入脑脊液很少,大多数患者脑脊液中药物浓度低于血浆浓度的10%。用药后12h43%由尿排出体外,其中2/3为原形。另外尚可由胆道排出。本药静脉注射后在血浆中迅速而完全地转变成依托泊苷。依托泊苷难以进入脑脊液。在体外,依托泊苷与血浆蛋白结合率高(97%);癌症患者及正常志愿者,依托泊苷的蛋白结合率与血清蛋白浓度有关。依托泊苷的体内过程呈一双相形式,其分布半衰期约为1.5h,终末消除半衰期为4~11h,机体总清除率为min33~48ml/m2或每分钟16~36ml/m2,与剂量无关。主要经肾(42%~67%)及胆汁(0%~16%)排泄。
适应证
1.小细胞肺癌:单药有效率38%,与顺铂联用有效率近80%。
2.恶性淋巴瘤:单药有效率36%。
3.对急性白血病、绒毛膜上皮癌及恶性葡萄胎疗效较好。
4.对睾丸肿瘤、卵巢癌、膀胱癌、前列腺癌也有效。
禁忌证
1.对本药过敏者。
2.白细胞和血小板明显低下者。
3.心、肝、肾功能有严重不全者。
注意事项
1.孕妇及哺乳期妇女慎用。
2.药物对儿童的影响:尚未明确儿童使用本药的安全性和有效性,但已有儿童对本药过敏的报道。
3.药物对妊娠的影响:美国食品和药物管理局(FDA)将本药妊娠分类为D类。本药对小鼠及大鼠胚胎有致畸性,对人类胚胎很可能也有致畸性。
4.药物对哺乳的影响:本药可经乳汁排泄,哺乳期妇女应慎用。
5.药物对检验值或诊断的影响:使用本药可能致肝酶升高,如天门冬氨酸氨基转移酶(AST)、丙氨酶氨基转移酶(ALT)、碱性磷酸酶(ALP)、乳酸脱氢酶(LDH)。
6.用药期间应定期检查周围血象、肝肾及心脏功能。
7.本药不宜静脉推注,注意不要漏出血管外。
8.本品在葡萄糖溶液中不稳定,可形成细微沉淀,因此应使用生理盐水稀释。
9.本品不能肌内注射。
10.长春新碱能抑制可溶性微管蛋白二聚物进入微管的解聚作用,影响神经微管的功能与轴索的运输,替尼泊苷可增加微管蛋白对长春新碱的亲和力或增加微管蛋白对长春新碱解聚作用的敏感性,因而二者合用可增强长春新碱的神经毒性。
不良反应
1.骨髓抑制:主要是白细胞减少,是最常见的剂量限制原因,血小板下降少见。2.胃肠道反应:恶心、呕吐、口腔炎、腹泻,一般较轻。
3.低血压:静脉内推注可出现低血压,故应静脉点滴给药,至少0.5h。
4.皮肤反应:脱发较常见,偶见皮炎、瘙痒。
5.其他:头痛、发热、心悸、心电图异常、静脉炎等,也有神经系统毒性。罕见的有肝毒性、末梢神经感觉异常,也有视神经炎、放射触发性皮炎等报道。尚报道有后遗异味、发热、色素沉着、吞咽困难、一过性皮质盲等不良反应。此外,本药对人体具有潜在的致癌作用。
用法用量
1.成人:静脉给药:
(1)睾丸生殖细胞肿瘤:BEP方案,即博莱霉素(BLM)每周30mg,分3次静脉注射;本药每天100mg/m2,连用5天,或每天120mg/m2,连用3天;顺铂(DDP)每天20mg/m2,连用5天。
(2)体积大、预后差的肿瘤:可用双倍顺铂的PVeBV方案,即DDP每天40mg/m2,连用4天(溶于3%氯化钠溶液中静脉滴注);长春碱(VLB)0.2mg/m2,连用5天。
(3)小细胞肺癌:可用经典的CAV方案,即环磷酰胺(CTX)、阿霉素(ADM)及长春新碱(VCR),与PV方案(DDP60~120mg/m2,只用1天;本药每天100mg/m2,连用5天)交替作用。
(4)非小细胞肺癌:用PV方案(见小细胞肺癌)治疗。
(5)胃癌:EAP方案:第1、7天每天使用ADM 20mg/m2,第2、8天使用DDP每天40mg/m2,第4~6天本药每天120mg/m2,均静脉注射给药。ELF方案,亚叶酸钙(LV)、氟尿嘧啶(5-FU)每天分别为300mg/m2、500mg/m2,连用3天,第3、5天静脉注射本药每天120mg/m2。这两种方案的疗效均优于过去常用的FAM方案。
(6)霍金奇淋巴瘤:采用EVA方案,本药每天100mg/m2静脉注射,连用3天,VLB6mg/m2,ADM50mg/m2。口服给药:每天70~100mg/m2,连用5天,或30mg/m2,连用10天。每3~4周为1个疗程。
2.临床上常与其他化疗药合用组成联合化疗方案:
(1)小细胞肺癌:
①老年人小细胞肺癌:总量800mg/m2,连用5天。
②顽固性小细胞肺癌:采用共6个月的长疗程,即每天50mg/m2,连服3周,休息1周。过去多次化疗者使用此方案,部分病例仍有效。
(2)霍奇金淋巴瘤:采用EVA方案,本药每天200mg/m2,连用5天,VCR2mg/m2,ADM50mg/m2。
3.儿童:静脉滴注:每天100~150mg/m2,连用3~4天。
药物相应作用
1.与阿糖胞苷、环磷酰胺、卡莫司汀有协同作用。
2.与其他抗肿瘤药物合用,可能加重骨髓抑制的不良反应。
3.与环孢素合用,当环孢素的血药浓度大于2000ng/ml时,可增加本药的分布容积并降低其清除率,从而使本药毒性增加。
4.与valspodar合用时,valspodar可导致本药清除率明显降低(40%~60%),合用时应减少本药用量的66%。
5.与他莫昔芬合用,可增加本药的毒性,但原因不明。
6.本药血浆蛋白结合率高,故凡可与血浆蛋白结合的药物都可影响本药的排泄。7.使用本药时,将增加活疫苗所致感染的危险。故禁止同时接种活疫苗(如轮状病毒疫苗)。处于缓解期的白血病患者,化疗结束后间隔至少3个月才能接种活疫苗。
