简介

部分中文硫酸长春新碱处方资料(仅供参考)

药物名称:硫酸长春新碱

英文名:Vincristine Sulfate

类别:抗肿瘤植物成分药

药理毒理:

长春新碱为夹竹桃科植物长春花中提取的有效成分。抗肿瘤作用靶点是微管,主要抑制微管蛋白的聚合而影响纺锤体微管的形成。使有丝分裂停止于中期。还可干扰蛋白质代谢及抑制RNA多聚酶的活力,并抑制细胞膜类脂质的合成和氨基酸在细胞膜上的转运。

长春新碱对移植性肿瘤的抑制作用大于长春花碱且抗瘤谱广。除对长春花碱敏感的瘤株有效外,对小鼠Ridgeway成骨肉瘤、Mecca淋巴肉瘤、X-5563骨髓瘤等也有作用。

长春新碱、长春花碱和长春地辛三者间无交叉耐药现象,长春新碱神经毒性在三者中最强。

药代动力学:

静注长春新碱后迅速分布于各组织,神经细胞内浓度较高,很少透过血脑屏障,脑脊液浓度是血浆浓度的1/30~1/20。蛋白结合率75%。在成人,t1/2α小于5分钟,t1/2β为50~155分钟,末梢消除相t1/2γ长达85小时。在肝内代谢,在胆汁中浓度最高,主要随胆汁排出,粪便排泄70%,尿中排泄5%~16%。长春新碱能选择性地集中在癌组织,可使增殖细胞同步化,进而使抗肿瘤药物增效。

适应症:

①.急性白血病,尤其是儿童急性白血病,对急性淋巴细胞白血病疗效显著。②.恶性淋巴瘤。③.生殖细胞肿瘤。④.小细胞肺癌,尤文肉瘤、肾母细胞瘤、神经母细胞瘤。⑤.乳腺癌、慢性淋巴细胞白血病、消化道癌、黑色素瘤及多发性骨髓瘤等。

用法用量:

成人剂量1~2mg(或1.4mg/m2)最大不大于2mg,年龄大于65岁者,最大每次1mg。儿童75μg/kg或2.0mg/m2,每周1次静脉注射或冲入。联合化疗是连用2周为一周期。

不良反应:

①.剂量限制性毒性是神经系统毒性,主要引起外周神经症状,如手指、神经毒性等,与累积量有关。足趾麻木、腱反射迟钝或消失,外周神经炎。腹痛、便秘,麻痹性肠梗阻偶见。运动神经、感觉神经和脑神经也可受到破环,并产生相应症状。神经毒性常发生于40岁以上者,儿童的耐受性好于成人,恶性淋巴瘤病人出现神经毒性的倾向高于其他肿瘤病人。

②.骨髓抑制和消化道反应较轻

。③.有局部组织刺激作用,药液不能外漏,否则可引起局部坏死。

④.可见脱发,偶见血压的改变。

注意事项:

①.仅用于静脉注射,漏于皮下可导致组织坏死、蜂窝织炎。一旦漏出或可疑外漏,应立即停止输液,并予相应处理(参考氮芥外漏的处理)。

②.防止药液溅入眼内,一旦发生应立即用大量生理盐水冲洗,以后应用地塞米松眼膏保护)。

③.冲入静脉时避免日光直接照射。

④.肝功能异常时减量使用。

药物相互作用:

1.吡咯系列抗真菌剂(伊曲康唑),增加肌肉神经系统的副作用。如发现有副作用,应进行减量、暂停或停药等适当处理。伊曲康唑有阻碍肝细胞色素P-450 3A的作用,长春新碱通过肝细胞染色素P-450 3A代谢,合用可使长春新碱代谢受抑制。

2.与苯妥英钠合用,降低苯妥英钠吸收,或使代谢亢进。

3.与含铂的抗亚、恶性肿瘤剂合用,可能增强第8对脑神经障碍。

4.与L-天冬酰胺酶合用,可能增强神经系统及血液系统的障碍。

为将毒性控制到最小,可将硫酸长春新碱在L-天冬酰胺酶给药前12-24小时以前使用。

贮藏:遮光,密闭,在冷处保存。
