药理作用

喷司他丁是拟嘌呤类的抗代谢药,其抗肿瘤作用是通过抑制体内的腺苷脱氨酶(ADA)来实现的。ADA催化细胞内的腺苷和脱氧腺苷进行不可逆的脱氨基,从而控制细胞内的腺苷水平。喷司他丁抑制了ADA的活性,结果使细胞内脱氧腺苷和5′-三磷酸脱氧腺苷(dATP)大量积累,而dATP的积累将最终导致细胞的死亡,这一过程可能与DNA或RNA的合成受到抑制有关。据报道,单一剂量的喷司他丁对ADA具有1周以上的抑制作用。

药代动力学

特性静脉注射后,喷司他丁迅速分布于机体组织,平均稳态分布容积为20.1L.m-2,分布相(α相)大约为30~85min。喷司他丁主要由肾脏排泄,24h内约有50%~96%的药物以原型由尿中排出。原型药物的终末相半衰期为3~15h,静注喷司他丁250μg.kg-1,连续4~5d后,血浆浓度范围为12~36nmol.L-1。临床用途干细胞白血病(hairycell leukemia,HCL) 这是FDA指定的适应症。HCL是一种不常见的慢性淋巴组织增生症,多见于40~60岁的男性,曾用α干扰素或脾切除术予以治疗。喷司他丁对HCL有良好的疗效,其中完全有效率为60%,部分有效率为84%~90%。同时喷司他丁还成功地应用于那些α干扰素非应答的患者,补救率为74%~86%[3]。慢性淋巴细胞白血病(chromic lymphocyticleukemia,CLL) 尽管喷司他丁对CLL有一定的疗效,但一般被用作二线药物,主要用于复发的Ⅲ,Ⅳ期的CLL患者[2]。蕈样霉菌病(mycosis fungoides) 一项二期临床实验表明,喷司他丁合用α2a干扰素对重度顽固蕈样霉菌病/红皮病有效。全部41名患者第1~3天静注喷司他丁4mg.m-2.d-1,同时肌注干扰素1×107u.m-2连续22d,第23~26天肌注干扰素5×107u.m-2,结果总有效率为41%。

用法与用量

喷司他丁可以用0.9%氯化钠注射液或5%葡萄糖注射液配制,溶液浓度应≥0.05mg.ml-1,最大为2mg.ml-1。建议HCL患者用量为4mg.m-2,隔周1次。肾衰患者的剂量应根据肌酐清除率调整,如出现严重的皮疹、感染、神经中毒的迹象应减少剂量或停药。静注喷司他丁之前,建议先给予患者5%的葡萄糖溶液500~1000ml进行水化。化疗之后,再给予患者5%的葡萄糖溶液或等量其它液体500ml。

不良反应

像其它一些抗肿瘤药物一样喷司他丁有许多不良反应,对血液、心血管、中枢神经系统、泌尿生殖系统等有着不良的影响。可引起骨髓抑制、心率失常、恶心、呕吐、腹泻、肝功能异常以及角结膜炎、皮疹等不良反应。剂量大于4mg.m-2时,还可能会出现嗜睡、昏迷、癫痫发作、血尿、BUN升高、血肌酐升高等症,甚至出现急性肾功能衰竭。

药物相互作用

喷司他丁与其它抗肿瘤药物联合应用时可能会产生严重的毒副作用。与两性霉素B联用可产生肾毒性、低血压、支气管痉挛,与环磷酰胺合用产生心脏毒性,而与氟达拉滨合用可能会产生肺毒性。当喷司他丁与阿糖腺苷联用时将同时增强两药的不良反应。

规格与贮存

本品为注射用粉针,每安瓿含喷司他丁10mg,供静脉注射,其中主要非活性成分是甘露醇。本品应贮存于2℃~8℃,由于不含防腐剂,本品一经配制后应于8h内用完
