泮托拉唑钠肠溶片在临床中主要用于消化性溃疡等疾病。
【主要成分】泮托拉唑钠。
【适应症】用于十二指肠溃疡、胃溃疡、反流性食管炎、卓艾综合症感染。
【用法用量】口服，每次40mg，每日一次，早晨服用，疗程2～4周。
【不良反应】偶见头晕、失眠、嗜睡、恶心、腹泻、便秘、皮疹和肌肉疼痛等症状，大剂量使用时可出现心律不齐，转氨酶升高，肾功能改变，粒细胞降低等。
【禁忌】对本品过敏的患者禁用。
【注意事项】
1、当怀疑胃溃疡时，应首先排除癌症的可能性，因为本品可减轻其症状，从而延误诊断。
2、肝肾功能不全者慎用。因本品经肝脏代谢，肾脏排泄，故肝功能损害患者若使用本品应减量使用，同时监测肝脏酶谱的变化，若测定值升高则应停止用药。肾功能受损的患者对此药代谢的影响不太明显，但也应控制日使用剂量不超过40mg.
3、本品抑制胃酸分泌的作用强，时间长，故应用本品时不宜同时再服用其它抗酸剂或抑酸剂。为防止抑酸过度，在一般消化性溃疡等病时，不建议大剂量长期应用（卓-艾综合征例外）。
