代谢
被肝脏和红细胞代谢,形成三乙醇,这是一种活性代谢物。这个反应是由醇脱氢酶和其他酶催化的。在肝脏和肾脏中,合物和三乙醇氧化成三氯乙酸的过程也有一定程度的进行。三乙醇还经历葡萄糖醛酸化,产生无活性的代谢物。
Metabolized by the liver and erythrocytes to form trichloroethanol, an active metabolite. This reaction is catalyzed by alcohol dehydrogenase and other enzymes. Oxidation of chloral hydrate and trichloroethanol to trichloroacetic acid in the liver and kidneys also occurs to a lesser extent. Trichloroethanol also undergoes glucuronidation to produce an inactive metabolism.

A small but variable amount of chloral hydrate and a larger portion of trichloroethanol are oxidized to trichloroacetic acid (an inactive metabolite), mainly in the liver and kidneys. Trichloroethanol may also be conjugated with glucuronic acid to form trichloroethanol glucuronide (urochloralic acid), an inactive metabolite. ...

代谢
在哺乳动物物种中,水合氯醛迅速还原为三乙醇,这种代谢物似乎是药物催眠特性的原因。在啮齿动物中,可以看到一种略有不同的代谢模式,因为水合氯醛直接被氧化成三氯乙酸,而在人类中观察到的从三乙醇三氯乙酸的氧化途径似乎不存在。
In mammalian species, chloral hydrate is rapidly reduced to trichloroethanol, the metabolite that appears to be responsible for the hypnotic properties of the drug. ... In rodents, a slightly different metabolic pattern is seen, as chloral hydrate is oxidized directly to trichloroacetic acid, and the oxidative pathway from trichloroethanol to trichloroacetate that is observed in humans seems to be absent.

  • 毒性总结
识别:水合氯醛在人类和兽药中被用作镇静剂和催眠药。人类暴露:普通公众的主要暴露途径是饮用,因为当饮用消毒时,会形成水合氯醛。由于水合氯醛三氯乙烯四氯乙烯的代谢物,如果人们暴露于这些化学物质,他们将会暴露于水合氯醛。公众也会暴露于水合氯醛的代谢物,三氯乙酸二氯乙酸,因为当饮用消毒时,这些化学物质也会形成。在其作为人类的镇静剂使用时,代谢物三乙醇负责药理效应。没有来自职业暴露的定量信息。水合氯醛对皮肤和粘膜有刺激性,在推荐的临床剂量下常引起胃部不适、恶心和呕吐。这种药物过量会导致(按进展顺序)共济失调、嗜睡、深度昏迷、呼吸抑制、低血压和心律失常。有一些证据表明,在幸存于近致命急性过量的情况下,人们会受到肝脏损伤。尽管水合氯醛在人类医学中使用了很长时间,但还没有关于长期暴露下人类对照研究的毒性的发表信息。水合氯醛在口服给药后会被完全吸收并迅速代谢。在人类中,三乙醇及其葡萄糖醛酸苷的半衰期约为8小时;三氯乙酸的半衰期约为4天。一些数据表明,早产儿和足月婴儿的三乙醇半衰期比幼儿和成人长几倍。水合氯醛代谢物的主要排泄途径是在尿液中排出。水合氯醛及其代谢物已在使用该药物的妇女的乳汁中发现。没有来自人类的致癌性数据。动物研究:给小鼠急性给药水合氯醛会导致失去协调(共济失调)。小鼠90天的研究没有显示出行为变化或其他神经毒性的证据。在大鼠和小鼠的慢性研究中,没有显示出行为变化和神经组织组织病理学变化的证据。在暴露于90天的小鼠中,观察到体液免疫力略有下降。在大鼠和小鼠中对该药物进行了发育效应测试。没有观察到结构异常。在小鼠的神经发育研究中,被动回避学习有轻微影响。在大鼠的两个生物鉴定中,没有在任何部位增加肿瘤。在雄性小鼠的三个独立生物鉴定中,肝脏肿瘤的发生率有所增加。这些数据中最具有决定性的研究表明,在三个暴露中,肝脏肿瘤的发生率和多发性在每个暴露中都有所增加。这些数据表明,水合氯醛在雄性小鼠中具有致癌性的提示性证据,但被认为不适合以线性响应进行低暴露的人类健康风险评估。各种结果表明,水合氯醛是一种弱基因突变剂和裂变剂。水合氯醛在多种细胞类型中诱导非整倍体。
IDENTIFICATION: Chloral hydrate is used in human and veterinary medicine as a sedative and hypnotic drug. HUMAN EXPOSURE: The major route of exposure of the general public is from drinking water, as chloral hydrate is formed when drinking water is disinfected with chlorine. Since chloral hydrate is a metabolite of trichloroethylene and tetrachloroethylene, people will be exposed to chloral hydrate if they are exposed to these chemicals. The public will be exposed to the metabolites of chloral hydrate, trichloroacetic acid and dichloroacetic acid, as these chemicals are also formed when drinking water is disinfected with chlorine. In its use as a sedative for people, the metabolite trichloroethanol is responsible for the pharmacologic effect. No quantitative information is available from occupational exposure. Chloral hydrate is irritating to the skin and mucous membranes and often causes gastric distress, nausea and vomiting at the recommended clinical dose. An overdose of this drug produces (in order of progression) ataxia, lethargy, deep coma, respiratory depression, hypotension and cardiac arrhythmia. There is some evidence of hepatic injury in people surviving near lethal acute overdoses. Despite its long use in human medicine there is no published information on toxicity in controlled studies in humans following extended exposure. Chloral hydrate is completely absorbed and rapidly metabolized following oral admin. In humans the half-life of trichloroethanol and its glucuronide is about 8 hr; the half-life of trichloroacetic acid is about 4 days. Some data suggest that half-life of trichloroethanol is incr several fold in pre-term and full term infants compared with toddlers and adults. The major routes of excretion of the metabolites of chloral hydrate is elimination in the urine.Chloral hydrate and its metabolites have been found in milk from women treated with this drug. There no carcinogenicity data from humans. ANIMAL STUDIES: Acute administration of chloral hydrate to mice causes loss of coordination (ataxia). A 90 day study in mice shows no evidence of behavioral changes or other neurotoxicity. Chronic studies in rats and mice show no evidence of behavioral changes and no evidence of histopathological changes in the nervous tissue. A slight detriment in humoral immunity was observed following exposure of mice for 90 days. This drug has been tested for developmental effects in rats and mice. No structural abnormalities were observed. In a neurodevelopmental study in mice, there was a slight effect in passive avoidance learning. Two bioassays in rats show no incr in tumors at any site. Three separate bioassays in male mice showed an incr incidence of liver tumors. The most definitive of these studies shows an incr incidence and multiplicity of liver tumors at each of three exposures. These data show suggestive evidence of carcinogenicity in male mice but are not considered appropriate for conducting a human health risk assessment with a linear response at low exposure. A variety of results show that chloral hydrate is a weak gene mutagen and clastogen. Chloral hydrate induces aneuploidy in a wide variety of cell types.

  • 肝毒性
水合氯醛已经在临床使用了几十年,并未发现与治疗期间血清酶平升高或临床上明显的肝脏损伤有关。尽管尚未进行水合氯醛对肝脏测试影响的前瞻性研究,但未见报告有归因于水合氯醛的肝脏损伤实例,这表明水合氯醛几乎或没有肝脏毒性。水合氯醛曾被报道与过敏反应有关,如皮疹、发热和嗜酸性粒细胞增多。水合氯醛还与口服抗凝剂、抗抑郁药和酒精有重大药物相互作用。在肝硬化及肝功能失代偿的患者中,水合氯醛可能触发或加重肝性脑病。 可能性评分:E(不太可能是临床上明显肝脏损伤的原因)。 药物类别:镇静剂和催眠药,其他。
Chloral hydrate has been in clinical use for many decades and has not been linked to serum enzyme elevations during therapy or instances of clinically apparent liver injury. While prospective studies of the effects of chloral hydrate on liver tests have not been done, the absence of reported instances of liver injury attributable to chloral hydrate suggests that it has little or no hepatic toxicity. Chloral hydrate has been linked to hypersensitivity reactions such as rash, fever and eosinophilia. Chloral hydrate also has major drug-drug interactions with oral anticoagulants, antidepressants and alcohol. In patients with cirrhosis and hepatic decompensation, chloral hydrate can trigger or worsen hepatic encephalopathy. Likelihood score: E (unlikely cause of clinically apparent liver injury). Drug Class: Sedatives and Hypnotics, Miscellaneous

  • 致癌性证据
证据权重特征:根据1986年的癌症指导方针(美国环保署),水合氯醛被归入C组,可能是人类致癌物。根据1996年提出的癌症风险评估指导方针(美国环保署),水合氯醛通过口服暴露途径显示出对人类致癌性的暗示性证据。目前没有来自人类的长肿瘤数据。两项通过饮用给予大鼠水合氯醛生物测定实验显示,在任何部位都没有肿瘤增加。因为这些生物测定实验中大鼠肝脏只观察到轻微的毒性,所以实验没有在最大耐受剂量下进行。一项对雌性小鼠的长期生物测定实验显示,在最高测试暴露平下,垂体前叶(pars distalis)腺瘤的严重程度等级略有增加,腺瘤的发生率也略有增加。有一些证据表明,水合氯醛会导致雄性小鼠肝细胞肿瘤。一项早期研究显示,单次大量暴露后肝细胞腺瘤或骨状细胞癌的增加无法在一项使用更多动物和高暴露的研究中得到证实。三项独立的、为期两年的雄性小鼠生物测定实验显示,肝细胞腺瘤或肝细胞癌的发生率增加。没有数据显示识别出肝细胞肿瘤的前兆病变。所使用的小鼠品系自发发生肝细胞肿瘤的几率非常高。水合氯醛的两个代谢物,三氯乙酸二氯乙酸,已被证明会在啮齿动物中引起肝细胞肿瘤。三氯乙酸只在小鼠中引起肝细胞肿瘤。二氯乙酸会在大鼠和小鼠中都引起肝细胞肿瘤。关于遗传毒性的数据库非常广泛。各种结果显示,水合氯醛是一种弱基因突变剂和断裂剂。水合氯醛会在多种细胞类型中诱导非整倍体。这些后期效应被认为是由纺锤体装置的破坏引起的。需要高浓度的水合氯醛才能引起可观察的效果。尽管这些数据表明遗传毒性可能在水合氯醛的毒性中发挥作用,但数据显示这些效果需要达到的浓度在生理条件下和通常从环境中遇到的暴露下不太可能发生。总的来说,这些数据提供了致癌性的暗示性证据,但证据权重不足以进行假设在低暴露下线性反应的风险评估。人类致癌性数据:无。动物致癌性数据:有限。
WEIGHT-OF-EVIDENCE CHARACTERIZATION: Under the 1986 cancer guidelines (EPA), chloral hydrate is assigned to Group C, possible human carcinogen. Under the 1996 proposed guidelines (EPA) for carcinogen risk assessment, chloral hydrate shows suggestive evidence of human carcinogenicity by the oral route of exposure. There are no carcinogenicity data from humans. Two bioassays in rats in which chloral hydrate was administered by drinking water show no increase in tumors at any site. Because only minimal toxicity was observed in the livers of the rats in these bioassays, the tests were not conducted at the maximum tolerated dose. A chronic bioassay in female mice showed a slight increase in the severity grade of hyperplasia and a slight increase in the incidence of adenoma in the pituatary gland pars distalis at the highest exposure tested. There is some evidence that chloral hydrate causes hepatocellular tumors in male mice. An earlier study showing an increase of hepatocellular adenomas or trabecular carcinomas following a single bolus exposure could not be confirmed in a study using more animals and higher exposures. Three separate 2-year bioassays in male mice show an increased incidence of hepatocellular adenoma or carcinoma. There are no data identifying a lesion that is a precursor to the hepatocellular tumors. The strain of mice used has a very high spontaneous incidence of hepatocellular tumors. Two of the matabolites of chloral hydrate, trichloroacetic acid and dichloroacetic acid, have been shown to cause hepatocellular tumors in rodents. Trichloroacetic acid causes hepatocellular tumors only in mice. Dichloroacetic acid causes hepatocellular tumors in both rats and mice. There is an extensive database on genetic toxicity. A variety of results show that chloral hydrate is a weak gene mutagen and clastogen. Chloral hydrate induces aneuploidy in a wide variety of cell types. These latter effects are thought to arise by disruption of the spindle apparatus. A high concentration of chloral hydrate is required to cause observable effects. Although these data suggest that genotoxicity may play a role in the toxicity of chloral hydrate, the data indicate that these effects require concentrations that are unlikely to occur under physiological conditions at the exposures typically encountered from the environment. Collectively, these data provide suggestive evidence of carcinogenicity, but the weight of evidence is not sufficient to conduct a risk assessment assuming a linear response at low exposure. HUMAN CARCINOGENICITY DATA: None. ANIMAL CARCINOGENICITY DATA: Limited.
