阿米替林（Amitriptyline）^[5]，商品名稱Elavil，是使用最广泛的一种止痛药。^[6] 阿米替林可以治疗许多精神障碍^[7]，包括重度抑郁症和焦虑症，有时候也用来治疗精神病、注意力缺陷多动障碍（ADHD，多动症）和双相情感障碍^[7]^[8]。阿米替林也可以預防偏头痛、治療包括纖維肌痛症及疱疹後神經痛（英语：postherpetic neuralgia）在内的神經性疼痛，偶爾也會被用於治療失眠^[7]^[9]。該藥屬於口服藥物^[7]。

常見的副作用包含口乾、視覺障礙、姿位性低血壓、嗜睡，以及便秘等等。嚴重的副作用可能會造成癲癇發作、尿滯留、青光眼，或是其他心臟問題，25歲以下的用藥者甚至會有增加自殺念頭的風險。該藥切忌與单胺氧化酶抑制剂或希塞菩（英语：cisapride）等藥物合用^[7]。妊娠時服用阿米替林可能具有風險^[10]^[7]，哺乳期間用藥目前認為是安全的^[11]。該藥為使用最廣泛的一種三環類抗抑鬱藥（TCA），然其詳細機轉仍不清楚^[7]。

在1960年首次發現阿米替林^[12]，並於1961年被美國食品藥品監督管理局核准^[13]。該藥列名世界衛生組織基本藥物標準清單當中，為基礎醫療體系的必備用藥之一^[14]。該藥屬於通用名藥物^[7]，2014年每劑的批發價價格區間位於0.01至0.04美金之間^[15]，美國境內則約一劑0.20美金左右^[7]。
