毒理性
  • 解毒与急救
由于抗组胺药过量没有特定的解毒剂,治疗是针对症状的支持性治疗,可能会使用以下方法:1)催吐(推荐使用吐根糖浆);然而,必须预防吸入,特别是在婴儿和儿童中。2)如果病人在摄入后三小时内无法呕吐,则进行洗胃(使用等渗或0.45%氯化钠溶液)。3)有时使用盐性泻药(乳剂)。4)使用血管加压药治疗低血压;然而,不应使用肾上腺素,因为它可能会进一步降低血压。5)氧气和静脉输液。6)预防使用刺激剂(兴奋剂),因为它们可能引起癫痫发作。/抗组胺药/
Since there is no specific antidote for overdose with antihistamines, treatment is symptomatic and supportive with possible utilization of the following: 1) Induction of emesis (syrup of ipecac recommended); however, precaution against aspiration necessary, especially in infants and children. 2) Gastric lavage (isotonic or 0.45% sodium chloride solution) if patient unable to vomit within three hours of ingestion. 3) Saline cathartics (milk of magnesia) are sometimes used. 4) Vasopressors to treat hypotension; however, epinephrine should not be used since it may further lower blood pressure. 5) Oxygen and intravenous fluids. 6) Precaution against use of stimulants (analeptic agents) because they may cause seizures. /Antihistamines/

毒理性
  • 非人类毒性摘录
在大鼠和家兔中使用口服富马酸氯马斯汀的剂量分别达到正常成人剂量的312倍和188倍进行的生殖研究没有发现对胎儿有害的证据。在大鼠和家兔中使用口服富马酸氯马斯汀盐酸丙醇胺以固定组合比例1:49,并且口服剂量达到100倍(大鼠)和67倍(家兔)正常成人剂量进行的生殖研究没有发现致畸效应。在大鼠中,将母体体重增加受损和死亡归因于在33倍正常成人剂量的盐酸丙醇胺,以及在100倍正常成人剂量的盐酸丙醇胺中发现的胎儿体重减轻和着床前损失以及产前死亡率的轻微增加。在家兔中,将母体死亡率的增加归因于20倍和67倍正常成人剂量的盐酸丙醇胺,以及在67倍正常成人剂量的盐酸丙醇胺中发现的母体体重减轻和产前死亡率的轻微(但在正常范围内)增加。
Reproduction studies in rats and rabbits using oral clemastine fumarate dosages up to 312 and 188 times the usual human adult dosage, respectively, have not revealed evidence of harm to the fetus. Reproduction studies in rats and rabbits using oral clemastine fumarate and phenylpropanolamine hydrochloride in a fixed combination ratio of 1:49 and at oral dosages up to 100 (in rats) and 67 (in rabbits) times the usual human dosage have not revealed evidence of teratogenic effects. Impaired maternal weight gain and death at 33 times the usual human dosage, and reduced fetal weight and slight increases in preimplantation loss and prenatal death at 100 times the usual human dosage were attributed to phenylpropanolamine in rats. Increased maternal death at dosages 20 and 67 times the usual human dosage, and maternal weight loss and a slight (but within normal limits) increase in prenatal death at a dosage 67 times the usual human dosage were attributed to phenylpropanolamine in rabbits.

吸收、分配和排泄
在12名健康受试者口服富马酸氯马斯汀后,血浆峰浓度在3到5小时后出现。在3名受试者静脉注射后,血浆浓度在前30分钟内迅速下降,然后在给药后2到3小时缓慢上升至峰值浓度。在5名给予富马酸氯马斯汀的受试者中,抑制组胺皮丘的能力与血浆浓度密切相关。
In 12 healthy subjects given clemastine fumarate by mouth peak plasma concentrations occurred after 3 to 5 hr. After intravenous injection in 3 subjects a rapid decline in plasma concentration during the first 30 minutes occurred followed by a slow rise to peak concentration 2 to 3 hours after administraton. In 5 subjects given clemastine fumarate the ability to inhibit histamine flares correlated well with plasma concentation.

吸收、分配和排泄
富马酸氯马斯汀能迅速且几乎完全从胃肠道吸收。单次口服给药后,药物在2-5小时内达到血浆峰浓度。口服富马酸氯马斯汀后,药物的的抗组胺效果(通过抑制皮内注射组胺引起的风团反应来衡量)在5-7小时内达到最大,并持续10-12小时,在某些人中可长达24小时。
Clemastine fumarate is rapidly and almost completely absorbed from the GI tract. Peak plasma concentrations of the drug are attained within 2-5 hours after a single oral dose. Following oral administration of clemastine fumarate, the antihistaminic effect of the drug (as measured by suppression of the wheal response induced by intradermal injection of histamine) is maximal within 5-7 hours and persists for 10-12 and, in some individuals, up to 24 hours.

吸收、分配和排泄
马斯汀在人体体液和组织中的分布尚未完全表征,但已经证明该药物可分布进入乳汁。在一项研究中,一名哺乳期妇女每天口服2.68毫克富马酸氯马斯汀,连续3天,最后一次给药后20小时,乳汁中马斯汀浓度约为5-10微克/毫升,约为同时期母体血浆药物浓度的25-50%;停止用药6天后,乳汁中检测不到马斯汀。
Distribution of clemastine into human body fluids and tissues has not been fully characterized, but the drug has been shown to distribute into milk. Following oral administration of 2.68 mg of clemastine fumarate daily for 3 days in one nursing woman, a milk clemastine concentration of about 5-10 ug/ml occurred 20 hours after the last dose of the drug and was about 25-50% of the stimultaneous maternal plasma drug concentration; clemastine was undetectable in milk 6 days after discontuance of the drug.

制备方法与用途

富马酸氯马斯汀是一种强效、长效、速效的组胺H1受体拮抗剂,临床主要用于过敏性皮肤病、过敏性鼻炎等过敏性疾病。它能够高选择性地阻断H1受体,并且对中枢神经系统的胆碱能受体没有抑制作用,无镇静和嗜睡作用,多用于过敏性鼻炎、抗过敏性哮喘、荨麻疹、湿疹、皮炎和皮肤瘙痒症等。近年来,“斯汀类”药物在局部给药方面日益受到重视,已开发出鼻用、眼科外用药,成为治疗过敏性鼻炎的一类非激素类药物。

药理作用

马斯汀属于二苯甲醚类组胺H1受体拮抗剂。它选择性地作用于H1受体,阻止组胺对靶细胞的作用,减少毛细血管通透性,并对抗5-羟色胺(5-HT)或胆碱的作用轻微。该药物具有较强的止痒效果,起效快,药效可持续12小时。

毒理作用

富马酸氯马斯汀在不同种属的动物中进行了毒理学试验,口服LD50为730~3550mg/kg,静脉注射LD50为19~82mg/kg。长期毒性试验显示,在大鼠和狗中服用不同剂量长达20-26周后未见明显毒性损害。此外,动物研究还表明马斯汀无胚胎毒性和致畸胎作用。

药代动力学

马斯汀能快速且几乎完全地被身体吸收,2-4小时达到血药浓度高峰,5-7小时抗组胺作用最强。其药效持续时间可达10-12小时,有时长达24小时。该药物的血浆蛋白结合率高达95%,其消除呈双相性,半衰期分别为3.6±0.9h和37±16h。活性物质主要在肝脏内代谢,约45-65%的代谢物通过肾脏排出,仅有少量以原形形式排出。

适应症

富马酸氯马斯汀适用于过敏性鼻炎、荨麻疹、湿疹及皮肤瘙痒症等过敏性疾病,还可用于支气管哮喘的抗过敏治疗。此外,它也可用于普通感冒引起的流鼻涕和打喷嚏。
