Upper gastrointestinal (GI) symptoms are common in patients using non-steroidal antiinflammatory drugs (NSAIDs) including selective cyclooxygenase (COX)-2 inhibitors and may be acid related. We therefore assessed esomeprazole treatment for upper GI symptoms in these patients.
A total of 794 and 848 continuous NSAID users, free of gastroduodenal ulcers, erosive esophagitis, and Helicobacter pylori, were enrolled into two identical, multinational, multicenter double-blind studies (NASA1, SPACE1). Moreover, 608 and 556 patients were randomized to receive 4 wk esomeprazole 20 mg, or 40 mg, or placebo once daily. The primary variable was the patient-reported change in the upper GI symptom (pain, discomfort, or burning in the upper abdomen) score on a 7-graded severity scale (0-6) from the 7 days prior to treatment to the last 7 days in the study.
Esomeprazole was associated with highly significant symptom improvement compared to placebo. Symptom improvements were 2.30 mean [SD 1.63] on esomeprazole 20 mg and 2.03 [1.56] on esomeprazole 40 mg versus 1.64 [1.57] on placebo in NASA1 and 2.17 [1.34] and 2.12 [1.48]versus 1.56 [1.26], respectively, in SPACE1 (all placebo comparisons at least p < 0.001). Esomeprazole-improved symptoms in patients taking selective COX-2 inhibitors, with changes of 2.21 [1.46] and 1.92 [1.38]versus 1.64 [1.46] in NASA1 and 2.20 [1.26] and 2.24 [1.62]versus 1.58 [1.37] in SPACE1 (all placebo comparisons at least p < 0.05), as well as those on non-selective NSAIDs. Esomeprazole was well tolerated and associated with significant improvements in HRQL.
Esomeprazole 20 mg and 40 mg improve upper GI symptoms associated with continuous, daily NSAID therapy, including selective COX-2 inhibitors.
上消化道(GI)症状在使用非甾体抗炎药(NSAIDs)包括选择性环氧化酶(COX)-2抑制剂的患者中很常见,且可能与胃酸有关。因此,我们评估了埃索美拉唑对这些患者上消化道症状的治疗效果。
共有794名和848名连续使用NSAIDs、无胃十二指肠溃疡、糜烂性食管炎和幽门螺杆菌感染的患者被纳入两项相同的、跨国的、多中心双盲研究(NASA1、SPACE1)。此外,608名和556名患者被随机分配接受4周的埃索美拉唑20毫克、或40毫克、或安慰剂,每日一次。主要变量是患者报告的上消化道症状(上腹部疼痛、不适或烧灼感)评分在7级严重程度量表(0-6)上从治疗前7天到研究最后7天的变化。
与安慰剂相比,埃索美拉唑使症状有高度显著改善。在NASA1研究中,埃索美拉唑20毫克组症状改善均值为2.30[标准差1.63],40毫克组为2.03[1.56],而安慰剂组为1.64[1.57];在SPACE1研究中,分别为2.17[1.34]、2.12[1.48]和1.56[1.26](所有与安慰剂比较均p<0.001)。埃索美拉唑改善了服用选择性COX-2抑制剂患者的症状,在NASA1研究中变化值为2.21[1.46]和1.92[1.38],而安慰剂组为1.64[1.46];在SPACE1研究中为2.20[1.26]和2.24[1.62],而安慰剂组为1.58[1.37](所有与安慰剂比较均p<0.05),服用非选择性NSAIDs的患者症状也有改善。埃索美拉唑耐受性良好,并与健康相关生活质量的显著改善相关。
埃索美拉唑20毫克和40毫克可改善与连续每日NSAID治疗相关的上消化道症状,包括选择性COX-2抑制剂。
