Omeprazole 我曾经翻阅过很多文章,类似《家庭医生》的科普文章，我也读过。我一直胃疼，发现它在美国的超市就有卖,不是处方药。买了一盒试了一下。 吃了有效果,但是，后来有胃疼有复发，再买来一看。需要坚持吃14天，后来不再胃疼了。我的症状是，肚子一饿就疼。 吃了后，它能附在胃上，隔离胃酸的刺激，不疼，坚持吃。胃及十二指肠溃疡慢慢修复就好了。下面是比较专业的说明，请看看，当然更重要的是，需要去看医生,问问医生的意见。

作用原理：
选择性地作用于胃粘膜壁细胞，抑制处于胃壁细胞顶端膜构成的分泌性微管和胞浆内的管状泡上的H+-K+-ATP酶的活性，从而有效地抑制胃酸的分泌，起效迅速，适用于胃及十二指肠溃疡，返流性食管炎和胃泌素瘤。由于H+、K+-ATP酶是壁细胞泌酸的最后一个过程，故本品抑酸能力强大，有强而持久的抑制基础胃酸及食物、五肽胃酸泌素所致的胃酸分泌的作用。 它不仅能非竞争性抑制促胃液素、组胺、胆碱及食物、刺激迷走神经等引起的胃酸分泌，而且能抑制不受胆碱或H2受体阻断剂影响的部分基础胃酸分泌，对H2受体拮抗剂不能抑制的由二丁基环腺苷酸（DcAMP）刺激引起的胃酸分泌也有强而持久的抑制作用。显效快，可逆，且无H2受体拮抗剂诱发精神方面的副作用。本品对胃蛋白酶分泌也有抑制作用，对胃黏膜血流量改变不明显，也不影响体温、胃腔温度、动脉血压、静脉血红蛋白、动脉氧分压、二氧化碳分压及动脉血pH。有强而持久的抑制基础胃酸及食物、五肽胃酸泌素所致的胃酸分泌的作用。显效快，可逆，且无H2受体拮抗剂诱发精神方面的副作用。用于胃及十二指肠溃疡、反流性或糜烂性食管炎、佐-埃二氏综合征等，对用H2受体拮抗剂无效的胃和十二指肠溃疡也有效。 用于胃及十二指肠溃疡、反流性或糜烂性食管炎、佐-埃二氏综合征等，对用H2受体拮抗剂无效的胃和十二指肠溃疡也有效。

作用与用途：
①消化性溃疡出血、吻合口溃疡出血。
②应激状态时并发的急性胃黏膜损害，和非甾体类抗炎药引起的急性胃黏膜损伤；
③亦常用于预防重症疾病（如 脑出血 、严重创伤等）胃手术后预防再出血等；
④全身麻醉或大手术后以及衰弱昏迷患者防止胃酸反流合并吸入性肺炎。
5、胃酸过多患者导致反流性胃炎的酸抑制，以及胃酸过多造成的严重烧心患者。
6、消化性溃疡胃十二指肠糜烂者，在治疗中也常常会用到奥美拉唑。

用法用量：
治疗胃溃疡、十二指肠溃疡、反流性食管炎：每日早晨吞服20mg(治疗十二指肠溃疡应于睡前服用，以减少空腹时十二指肠疼痛症状）。胃内食物充盈时，可减少吸收，故应餐前或空腹口服。本品治疗十二指肠溃疡疗程通常为2-4周，治疗胃溃疡及反流性食管炎疗程为4-8周.
