  • 毒性总结
托非索帕姆不与γ-氨基丁酸受体的苯二氮卓结合位点结合。一项研究(Rundfeldt C.等人)表明,托非索帕姆作为磷酸二酯酶(PDEs)的异酶选择性抑制剂,对PDE-4A1的亲和力最高(0.42微摩尔/升),其次是PDE-10A1(0.92微摩尔/升)、PDE-3(1.98微摩尔/升)和PDE-2A3(2.11微摩尔/升)。
Tofisopam does not bind to the benzodiazepine binding site of the gamma-aminobutyric acid receptor. One study (Rundfeldt C. et al.) has shown that tofisopam acts as an isoenzyme-selective inhibitor of phosphodiesterases (PDEs) with highest affinity to PDE-4A1 (0.42 _Мц_M) followed by PDE-10A1 (0.92 _Мц_M), PDE-3 (1.98 _Мц_M) and PDE-2A3 (2.11 _Мц_M).

毒理性
  • 症状
在苯二氮卓类药物中毒中,意识障碍的出现相对较快。剂量较大且作用时间较短的药物发生后,意识障碍出现得更快。最常见的初始症状是嗜睡。在摄入非常大的剂量后,这可能会进展为昏迷(一级或二级)。
The onset of impairment of consciousness is relatively rapid in benzodiazepine poisoning. Onset is more rapid following larger doses and with agents of shorter duration of action. The most common and initial symptom is somnolence. This may progress to coma (Grade I or Grade II) following very large ingestions.

  • 暴露处理
一般支持性措施应予以实施,同时静脉输液,并保持气道通畅。低血压可以通过使用去甲肾上腺素或美拉明来对抗。透析的价值有限。氟马西尼(安易醒)是一种竞争性的苯二氮卓受体拮抗剂,可以用作苯二氮卓过量的解毒剂。特别是,氟马西尼在逆转与苯二氮卓相关的中枢神经系统抑制方面非常有效,但在逆转呼吸抑制方面效果较差。然而,其使用存在争议,因为它有许多禁忌症。长期使用苯二氮卓的患者、摄入降低癫痫发作阈值的物质的患者、或有心动过速或癫痫病史的患者禁忌使用。通常情况下,医疗观察和支持性护理是治疗苯二氮卓过量的主要方法。尽管苯二氮卓可以通过活性炭吸收,但在纯苯二氮卓过量时,使用活性炭进行胃部净化并不有益,因为不良反应的风险通常超过了该程序可能带来的任何潜在益处。只有在苯二氮卓与其他可能从净化中受益的药物联合使用时,才建议使用。胃灌洗(胃抽吸)或全肠灌洗也不推荐。
General supportive measures should be employed, along with intravenous fluids, and an adequate airway maintained. Hypotension may be combated by the use of norepinephrine or metaraminol. Dialysis is of limited value. Flumazenil (Anexate) is a competitive benzodiazepine receptor antagonist that can be used as an antidote for benzodiazepine overdose. In particular, flumazenil is very effective at reversing the CNS depression associated with benzodiazepines but is less effective at reversing respiratory depression. Its use, however, is controversial as it has numerous contraindications. It is contraindicated in patients who are on long-term benzodiazepines, those who have ingested a substance that lowers the seizure threshold, or in patients who have tachycardia or a history of seizures. As a general rule, medical observation and supportive care are the mainstay of treatment of benzodiazepine overdose. Although benzodiazepines are absorbed by activated charcoal, gastric decontamination with activated charcoal is not beneficial in pure benzodiazepine overdose as the risk of adverse effects often outweigh any potential benefit from the procedure. It is recommended only if benzodiazepines have been taken in combination with other drugs that may benefit from decontamination. Gastric lavage (stomach pumping) or whole bowel irrigation are also not recommended.

制备方法与用途

性状:淡黄白色结晶粉末。溶于乙酸,微溶于丙酮、95%乙醇,难溶于乙醚。1%的95%乙醇溶液不显示旋光力。

药理作用:本品是一种短时效苯二氮卓类衍生物,具有类似于安西泮的抗焦虑活性,但肌肉松弛和睡眠增强效果较弱。适用于治疗更年期障碍及伴随自主神经症状(如心悸、多汗、头痛、体重变化及其他不适感)。

适应症:主要用于缓解头痛、头部沉重感、疲倦感、心动过速等症状;以及由自律神经失调引起的出汗等问题,也用于治疗因头部或颈部损伤导致的症状,更年期障碍和卵巢功能缺失等病症。

用法用量:成人每日口服3次,每次一片。可根据年龄与症状调整剂量。

不良反应:

  1. 易产生药物依赖。
  2. 神经系统:呼吸困难、头晕、摇晃、头痛、失眠、焦虑、躁狂症、抑郁症状、震颤、麻木等。
  3. 消化道:恶心、呕吐、口干、食欲不振、便秘、腹痛、腹泻等。
  4. 过敏反应:皮疹、瘙痒、发热、面部水肿等。
  5. 肝脏:AST(GOT)、ALT(GPT)水平上升等。
  6. 其他不适:乏力、心悸、血压升高、潮热、泌乳分泌增多及月经异常等。

孕妇及哺乳期妇女用药:

  1. 孕妇或可能怀孕的女性应权衡治疗益处与潜在风险后谨慎使用。苯并二氮类药物可能导致新生儿出现护理困难、呕吐、活动减少、肌张力下降、嗜睡、呼吸抑制/暂停,以及紫绀等症状。
  2. 哺乳期妇女若需服用此药,则应避免哺乳。
