药品介绍
商標名
ELPLAT I. V. INFUSION SOLUTION
药品英文名
Paclitaxel
药理作用
紫杉醇是一种新型的抗微管药物,可促进微管双聚体装配成微管,而后通过防止去多聚化过程而使微管稳定,这种稳定化作用抑制微管网正常动力学重组,而微管网的重组对于细胞生命间期和分裂功能是必要的。除此之外,本药还可导致整个细胞周期微管“束”的排列异常和细胞分裂期间微管多发性星状体的产生。体外实验表明紫杉醇具有显著的放射增敏作用,可能是使细胞活动停止于放射敏感的G2和M期。
药动学
静脉给药后,血浆浓度呈一双相性降低曲线。第一个快速下降表示药物分布到周边室和大量的清除,后一个时相部分是由于药物从周边室相对低速地流出。绝大多数与血浆蛋白结合,组织分布广。在肝脏代谢,主要经胆道排泄,很少从肾脏排出。
适应证
1.卵巢癌、乳腺癌,作为一线或二线药物。
2.肺癌。
3.头颈部癌
4.其他肿瘤:对恶性黑素瘤、晚期食管癌、胃癌、膀胱癌、精原细胞瘤、复发性非霍奇金淋巴瘤、脑瘤等有效。
禁忌证
1.对本药或聚氧乙烯化蓖麻油过敏者。
2.妊娠及哺乳妇女。
3.白细胞计数低于1.5×10^9/L的严重骨髓抑制者。
4.中性粒细胞计数低于1.0×10^9/L的艾滋病相关性卡波西肉瘤患者。
注意事项
1.以下情况慎用:
(1)有心脏传导功能异常者;
(2)有低血压或心动过缓者;
(4)有周围神经病变者。
2.使用本品前必须预防用药。
3.对聚氧乙基代蓖麻油过敏者忌用本品。
4.用药期间应进行心电监护。
5.用药期间及用药后应注意监测血象,中性粒细胞计数低于1.5×10^9/L或血小板低于100×10^9/L的患者禁用本品。
6.本品不能接触含聚氯乙烯的塑料制品,只能用玻璃瓶或聚乙烯输液器;静脉滴注时应先经过直径不超过0.22微米微孔膜的滤过。
不良反应
1.骨髓抑制:
是本品的主要剂量限制性毒性。常见中性粒细胞减少,且与剂量有关,低谷平均出现在给药后第11天。血小板减少较少见。贫血发生率和严重程度随着接受本品量的增多而增加,血红蛋白小于80g/L者约24%。用药期间,使用细胞集落刺激因子(如G-CSF)可有效地预防严重骨髓抑制的发生。
2.过敏反应:
可能与稀释剂—聚氧乙基代蓖麻油有关,多发生在用药后最初的10min内。发生率为39%,其中严重者2%。最常见的症状为皮肤潮红、皮疹,严重者出现呼吸困难、低血压、休克,甚至出现血管神经性水肿,可致死亡。
3.心血管毒性:
低血压(25%)、心动过缓(12%),33%的患者出现心电图异常,少数患者可发生完全性房室传导阻滞。
4.神经毒性:
62%出现周围神经毒性,最常见的表现为轻度麻木,约4%的患者有严重的神经系统症状。另外,尚有本药致癫痫大发作的报道。出现神经毒性者在以后的治疗中减少20%的本品用量。同时服用烟酰胺及维生素B1可能减少神经毒性的发生。
5.胃肠道反应:
恶心、呕吐等较常见,一般为轻度至中度。
6.其他:
脱发几乎发生于所有患者。关节痛、肌肉痛常见,几天内恢复。少数患者有肝功能异常。
用法用量
1.单药剂量:135~200mg/m2,加入生理盐水或5%葡萄糖溶液250~500ml中静脉滴注3h,每3周给药1次。2.联合用药:剂量为135~175mg/m2,3~4周重复。3.每周疗法:60~90mg/m2,每周1次,连用6周休2周为1个周期。研究证明,此方法疗效较好而不良反应较轻。
4.为防止过敏反应,给药前应预防用药:地塞米松10~20mg,于给本药前12h和6h各1次,口服;用药前0.5h口服或肌内注射苯海拉明50mg,并静脉注射西咪替丁300mg。
药物相应作用
1.由于奎奴普丁/达福普汀是细胞色素P450-3A4酶抑制剂,同时给药可增加本药血药浓度。
2.与特拉珠玛合用,特拉珠玛的血清谷浓度水平增加约1.5倍。临床试验证明二者合用效果较好。
3.顺铂可使本药的清除率降低约1/3,若使用顺铂后再给本药,可产生更为严重的骨髓抑制。
4.与阿霉素合用,研究表明先给本药24h持续滴注,再给阿霉素48h持续滴注,可明显降低阿霉素的清除率,加重中性粒细胞减少和口腔炎。
5.使用本药后立即给予表柔比星,可加重本药毒性。
6.酮康唑可抑制本药的代谢。
7.磷苯妥英钠、苯妥英钠可通过诱导细胞色素P450而降低本药作用。
8.使用本药时接种活疫苗(如轮状病毒疫苗),可增加活疫苗感染的风险。国外资料建议使用本药时禁止接种活疫苗。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。
专家点评
紫杉醇是近年来备受关注的一种新型植物抗肿瘤药,目前已成为卵巢癌及乳腺癌的一线治疗药物;紫杉醇加顺铂是目前治疗非小细胞肺癌最有效的方案之一;该药对头颈部癌、食管癌、胃癌等也显示较好疗效。体外实验表明,紫杉醇具有显著的放射增敏作用,因此常与放疗联合用于治疗肺癌、头颈部肿瘤等。该药的独特不良反因为过敏反应,初期应用有致死的报道,故使用时必须预防用药。


IMPORTANT WARNING:
Paclitaxel injection must be given in a hospital or medical facility under the supervision of a doctor who is experienced in giving chemotherapy medications for cancer.
Paclitaxel injection may cause a large decrease in the number of white blood cells (a type of blood cell that is needed to fight infection) in your blood. This increases the risk that you will develop a serious infection. You should not receive paclitaxel if you already have a low number of white blood cells. Your doctor will order laboratory tests before and during your treatment to check the number of white blood cells in your blood. Your doctor will delay or interrupt your treatment if the number of white blood cells is too low. Call your doctor immediately if you develop a temperature greater than 100.4 °F (38 °C); a sore throat; cough; chills; difficult, frequent, or painful urination; or other signs of infection during your treatment with paclitaxel injection.
Paclitaxel injection is manufactured with additional ingredients to allow the medication to reach parts of the body where it is needed. One form of paclitaxel injection (Abraxane) is manufactured with human albumin, and the other form of paclitaxel injection (Onxol, Taxol) is manufactured with a solvent called polyoxyethylated castor oil. There are important differences between the two forms of paclitaxel, so these products should not be substituted for each other.
If you are using the form of paclitaxel injection that is manufactured with polyoxyethylated castor oil, you may experience a serious or life-threatening allergic reaction. You will receive certain medications to help prevent an allergic reaction before you receive each dose of paclitaxel. Tell your doctor if you experience any of the following symptoms of an allergic reaction: rash; hives; itching; swelling of the eyes, face, throat, lips, tongue, hands, arms, feet, or ankles; difficulty breathing or swallowing; flushing; fast heartbeat; dizziness; or fainting.
Keep all appointments with your doctor and the laboratory. Your doctor will order certain tests to check your body's response to paclitaxel injection.
Talk to your doctor about the risks of receiving paclitaxel injection.
Why is this medication prescribed?.Paclitaxel injection manufactured with human albumin is used to treat breast cancer that has not improved or that has come back after treatment with other medications. Paclitaxel injection manufactured with polyoxyethylated castor oil is used to treat ovarian cancer (cancer that begins in the female reproductive organs where eggs are formed), breast cancer, and lung cancer. Paclitaxel injection with polyoxyethylated castor oil is also used to treat Kaposi's sarcoma (a type of cancer that causes patches of abnormal tissue to grow under the skin) in people who have acquired immunodeficiency syndrome (AIDS). Paclitaxel is in a class of medications called antimicrotubule agents. It works by stopping the growth and spread of cancer cells.
How should this medicine be used?.Paclitaxel injection comes as a liquid to be given intravenously (into a vein) by a doctor or nurse in a hospital or clinic. It is usually given once every 3 weeks. When paclitaxel injection manufactured with polyoxyethylated castor oil is used to treat Kaposi's sarcoma, it may be given once every 2 or 3 weeks.
Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
Other uses for this medicineReturn to top .
Paclitaxel injection is also sometimes used to treat cancer of the head and neck, esophagus (tube that connects the mouth and stomach), bladder, endometrium (lining of the uterus), and cervix (opening of the uterus). Talk to your doctor about the risks of using this medication for your condition.
