可待因是通过肝代谢转换为吗啡和诺科丁的半衰期为2至4小时的。如果摄入可待因,在最初的24小时内,可待因与吗啡的比率通常超过尿液的1.0。24小时后,该比率可能低于1.0;30小时后,只能检测到吗啡。
吗啡是从罂粟植物获得的一种天然存在的麻醉镇痛药,Papaver somniferum。吗啡是通过肝代谢转化为2至4小时的正态的。尿液中吗啡的存在可能表明2至3天内暴露于吗啡,海洛因或可待因。摄入含有罂粟种子的面包产品也可能导致吗啡在尿液中排泄。如果消耗过多的量,这可能导致摄入后6至12小时的尿液吗啡浓度高达2000 ng/ml。
氢可酮表现出复杂的代谢模式,包括O-二甲基化,N-甲基化和6-酮对6β羟基甲替代谢物的还原。氢酮和非氢可酮都是氢可酮的代谢产物。二氢可碱也是次要代谢物。在存在大约100倍高的羟考酮或氢电话的情况下,还可以发现痕量的氢可酮,因为它可以是这些药物中的药物杂质。氢可酮的存在大于100 ng/mL,表明在试样收集前2至3天内暴露。
Hydromorphone is metabolized primarily in the liver and is excreted primarily as the glucuronidated conjugate, with small amounts of parent drug and minor amounts of 6-hydroxy reduction metabolites. The presence of hydromorphone greater than 100 ng/mL indicates exposure within 2 to 3 days prior to specimen collection. Hydromorphone is also a metabolite of hydrocodone; therefore, the presence of hydromorphone could also indicate exposure to hydrocodone.
Dihydrocodeine是一种通过可待因的氢化制备的半合成性麻醉镇痛药。它也是氢可酮的小型代谢物。它被代谢为二氢吗啡,半衰期为3.4至4.5小时。
羟考酮被代谢为Noroxycodone,oxymorphone及其葡萄糖醛酸酮,主要通过肾脏排出。大于100 ng/mL的羟考酮的存在表明在收集样品前2至3天内暴露于羟考酮。
矛盾is metabolized in the liver to noroxymorphone and excreted via the kidney primarily as the glucuronide conjugates. Oxymorphone is also a metabolite of oxycodone and, therefore, the presence of oxymorphone could also indicate exposure to oxycodone.
纳洛酮是一种合成的麻醉拮抗剂,用于自然或合成阿片类药物引起的阿片类药物抑郁症的部分或完全逆转。它也已被纳入阿片类药物的口服片以阻止滥用。作用的持续时间取决于给药的剂量和途径。成人的半衰期约为30至81分钟。
The detection interval for the opiates is generally 2 to 3 days after last ingestion.

鸦片中存在于患者尿液中,既是尿液,也存在于硫酸盐或葡萄糖醛酸糖偶联物中。标本最初由免疫测定法筛选。鸦片测定法基于通过光传输变化测量的溶液中微粒的动力学相互作用。在没有样品药物的情况下,可溶性药物结合物与抗体结合的微粒结合,导致颗粒聚集体的形成。随着聚集反应在没有样品药物的情况下进行的,吸光度会增加。当尿液样品含有所讨论的药物时,该药物会与用于结合微粒抗体的药物衍生物结合物竞争。与样品药物结合的抗体不再可用以促进颗粒聚集,随后抑制了颗粒晶格的形成。样品药物的存在减少了与样品中药物浓度成比例的吸光度增加。样品药物含量是根据已知的临界药物浓度获得的值确定的。
The NADH formed during the reaction, measured photometrically as a rate of change in absorbance, is directly proportional to the ethyl alcohol concentration.(Package insert: Opiates. Roche Diagnostics; 11/2017)
After screening, enzyme hydrolysis is used to liberate the conjugated drug. Specimens are then centrifuged, diluted, and the analytes are separated by liquid chromatography-tandem mass spectroscopy and analyzed by multiple reaction monitoring.(Unpublished Mayo method)
