現(xiàn)狀及發(fā)展方向2前言自氯丙嗪的抗精神病作用被發(fā)現(xiàn)60年來，已經(jīng)上市的精神藥物已經(jīng)達(dá)到130余種。這些藥物在精神疾病或癥候群的治療或緩解方面正在發(fā)揮愈來愈重要的作用。如何選好、用好精神藥物，保證精神疾病藥物治療的有效性和安全性是精神科面臨的一個重要問題。治療藥物監(jiān)測是實(shí)現(xiàn)精神疾病的個體化精準(zhǔn)藥物治療的重要手段。3對精神藥物實(shí)施TDM的必要性精神疾病多屬慢性病，需要長期用藥，而且精神藥物的不良反應(yīng)較多；精神藥物在藥動學(xué)上的個體差異明顯，相同劑量的血濃度可相差幾倍到幾十倍；起效時(shí)間長，通常給藥2~4周后起效；療效指標(biāo)不夠簡明，且受醫(yī)生主觀因素影響；精神病患者的服藥依從性差；中毒反應(yīng)可隱匿性出現(xiàn)，且不易與疾病本身癥狀的加重相區(qū)別；血藥濃度與療效和毒副作用相關(guān)，過高或過低療效均不好。BenefitsofTDMinPsychiatrydosagetitrationadversereactionandintoxication(overdose)identificationpharmacogeneticparticularityevaluationdruginteractionevaluationrelapsepreventionpatient’scomplianceassessment45需要進(jìn)行TDM的藥物種類抗抑郁藥物三環(huán)類抗抑郁藥新型抗抑郁藥抗精神病藥傳統(tǒng)抗精神病藥非典型抗精神病藥情感穩(wěn)定劑碳酸鋰、丙戊酸、卡馬西平、拉莫三嗪戒毒藥及其它6精神藥物TDM必要性的等級劃分最應(yīng)該監(jiān)測的藥物（15種）鋰鹽、阿米替林（去甲替林）、丙咪嗪（去甲丙咪嗪）、氯丙咪嗪（去甲氯丙咪嗪）、去甲替林、氟哌啶醇、奮乃靜、氟奮乃靜、甲硫噠嗪、甲哌丙嗪、氨磺必利、氯氮平（去甲氯氮平）、奧氮平、苯巴比妥、苯妥英鈉應(yīng)該監(jiān)測的藥物（52種）多慮平（去甲多慮平）、麥普替林、西酞普蘭、氟西?。ㄈゼ追魍。?、舍曲林、文拉法辛（o-去甲文拉法辛）、曲唑酮、度洛西汀、米氮平、依他普侖、米那普侖、氯丙嗪、舒必利、利培酮（9-羥利培酮）、喹硫平、舍吲哚、溴哌利多、阿立哌唑、齊拉西酮、氟哌噻噸、卡馬西平、拉莫三嗪、丙戊酸、美沙酮等監(jiān)測有用的藥物（44種）潛在有用的藥物（19種）HistoryofTDMinChinavd.HELMHJ,ANDRIESSED.ClinChimActa.1961;6:747-748.王見義;吳貞喜;葛志榮.
