部分中文溴吡斯的明处方资料(仅供参考)

分类名称
一级分类:神经系统药物 二级分类:作用于自主神经系统的药物 三级分类:抗胆碱酯酶药 
 
药品英文名
Pyridostigmine Bromide
 
药品别名
吡斯的明、吡啶斯的明、溴化吡啶斯的明、美斯的侬、美定隆、溴吡啶斯的明、Bromurede、Mestinon、Regonol、Pyridostigmine bromide
 
药物剂型
1.片剂:60mg;
2.注射剂(粉):1mg,5mg,10mg;
3.糖浆剂:12mg(1ml);
4.缓释片:180mg。
 
药理作用
本品为季铵化合物。作用类似新斯的明。作用开始较迟,而持续时间较长。
 
药动学
本品难从胃肠道吸收。既被胆碱酯酶水解,也在肝内代谢。本品主要以原药和代谢物随尿排出。本品极少进入CSF,但可透过胎盘,少量进入乳汁。
 
适应证
重症肌无力、麻痹性肠梗阻,也可用于逆转非除极肌松药产生的神经肌肉阻滞,但一般认为其效力不如新斯的明。虽然也可用于术后尿潴留,但当前常被导尿管所取代。
 
禁忌证
1.对本品过敏者、孕妇和哺乳者禁用。
2.机械性肠梗阻和尿路梗阻者禁用。
 
注意事项
1.慎用:(1)支气管哮喘患者;(2)术后肺不张或肺炎患者;(3)心律失常尤其是房室传导阻滞者。
2.药物对妊娠的影响:孕妇给药后,由于子宫肌收缩,可引起早产。FDA妊娠分类为C类。
3.药物对哺乳的影响:少量可分泌入乳汁中。常用剂量时,婴儿通过乳汁摄入的药物量极少,乳母可安全用药。
4.重症肌无力患者:重症肌无力患者用药须谨慎,过量时可造成神经肌接头的除极型阻滞,出现肌无力现象,即“胆碱能危象”。
5.注射给药限用于拮抗非除极肌松药,注射给药后应作严密观察。
6.口服用的糖浆或缓释片一般仅供重症肌无力治疗用。因缓释片的用量大,毒性反应也较多发生,小儿一般不用。
7.本药的某些不良反应(如心动过缓,唾液多和胃肠道症状等)比新斯的明轻。
8.使用本药应严格遵守医嘱用药,并按时做记录;漏服药后不可服用双倍量;重症肌无力患者用量要恰到好处,过量时可发生胆碱能危象。
9.本药过量的特征有:视物模糊、恶心、呕吐或(和)腹泻,严重时可导致低血钾、呼吸短促、呼吸困难、喘鸣或(和)胸闷、唾液和气管支气管黏液分泌增多,甚至可引起肺不张、胃痉挛性疼痛、脉搏减慢等,由于毒蕈样作用,可导致上肢、颈、肩、舌等处肌肉出现麻痹状态,言语不清、行动不便、步态不稳、神志不清、抽搐或阵挛等。本药中毒量时出现胆碱能危象,临床表现系胆碱样和毒蕈样毒性反应的混合。使用阿托品或东莨菪碱均能予以解除。
 
不良反应
1.长期口服可出现溴化物的反应,如皮疹、乏力、恶心和呕吐等,且比溴新斯的明严重。
2.可出现轻度的抗胆碱酯酶的毒性反应,如腹痛、腹泻、唾液增多、气管内黏液分泌增加、出汗、缩瞳、血压下降和心动过缓等,一般均能自行消失。
3.凡是对溴化物过敏者,对本品也过敏。
 
用法用量
1.治疗重症肌无力:每天总量为0.3~1.2g,也有专家认为日总量不应超过720mg。全日用量,应分次给予,包括夜间;如有必要,在明显乏力的时候,应给予较大部分的药量。儿童用量为每天7mg/kg,5~6次分服。每天可逐步增加剂量15~30mg,总用量为每天30~360mg。也可采用肌内注射,严重病例还可很缓慢静脉注射。不过,静脉注射有一定的危险性,应备好阿托品,以抵消严重的毒蕈碱反应。
2.新生儿肌无力:可肌内注射50~150μg/kg,或口服5~10mg,每4~6小时1次。不过,临床更愿意使用新斯的明。
3.逆转由非除极肌松药产生的神经肌肉阻滞:可静脉给予本品10~20mg,此前,先给予阿托品0.6~1.2mg,以抵消任何毒蕈碱作用。格隆溴铵可用来替代阿托品。
4.治疗麻痹性肠梗阻和术后尿潴留:可口服本品60~240mg。
 
专家点评
本品起效缓慢,作用较溴化新斯的明弱但持续时间较久,引起的心动缓慢、唾液分泌和消化道反应较轻。一般认为本品对抗非除极化型肌松药过量的效果不如新斯的明好。
