Selective cyclooxygenase-2 (COX-2) inhibitors cause significantly fewer peptic ulcers than conventional nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) in patients at low risk or high risk for peptic ulcers. On the other hand, proton pump inhibitor co-therapy has also been shown to be effective in preventing relapse of peptic ulcers in high-risk patients using nonselective NSAIDs. We compared the efficacy of a selective COX-2 inhibitor with that of proton pump inhibitor co-therapy in the reduction in the incidence of ulcer relapse in patients with a history of NSAID-related peptic ulcers.
For this study, we recruited 224 patients who developed ulcer complications after NSAID use. We excluded patients who required concomitant aspirin treatment and who had renal impairment. After healing of ulcers and eradication of Helicobacter pylori, patients were randomly assigned to treatment with celecoxib 200 mg daily (n = 120) or naproxen 750 mg daily and lansoprazole 30 mg daily (n = 122) for 24 weeks. The primary endpoint was recurrent ulcer complications.
During a median follow-up of 24 weeks, 4 (3.7%, 95% confidence interval [CI] 0.0%-7.3%) patients in the celecoxib group, compared with 7 patients (6.3%, 95% CI 1.6%-11.1%) in the lansoprazole group, developed recurrent ulcer complications (absolute difference -2.6%; 95% CI for the difference -9.1%-3.7%). Celecoxib was statistically non-inferior to lansoprazole co-therapy in the prevention of recurrent ulcer complications. Concomitant illness (hazard ratio 4.72, 95% CI 1.24-18.18) and age 65 years or more (hazard ratio 18.52, 95% CI 2.26-142.86) were independent risk factors for ulcer recurrences. Significantly more patients receiving celecoxib (15.0%, 95% CI 9.7-22.5) developed dyspepsia than patients receiving lansoprazole (5.7%, 95% CI 2.8-11.4. P = .02).
Celecoxib was as effective as lansoprazole co-therapy in the prevention of recurrences of ulcer complications in subjects with a history of NSAID-related complicated peptic ulcers. However, celecoxib, similar to lansoprazole co-therapy, was still associated with a significant proportion of ulcer complication recurrences. In addition, more patients receiving celecoxib developed dyspepsia than patients receiving lansoprazole and naproxen.

    ABSTRACT: NSAIDs are prescribed widely but have rare serious gastrointestinal side effects. More recently, adverse cardiovascular effects of these drugs have also been recognized, leading to the withdrawal of some agents and continuing uncertainty about the best approach for patients requiring NSAID therapy. Proton pump inhibitors (PPIs) provide potent and long-lasting inhibition of gastric acid secretion and have proven efficacy in healing NSAID-associated ulcers, including those with continued exposure to NSAIDs. PPIs have also shown efficacy in reducing the risk of ulcerations due to NSAID use compared with NSAIDs alone in randomized controlled trials (RCTs) where endoscopic ulcers are used as the primary endpoint, albeit a surrogate marker for clinical ulcers and complications. Large RCT outcome trials comparing patients exposed to NSAIDs with and without PPI co-therapy have not been performed, but adequately powered RCTs in high-risk patients demonstrate that PPI + nonselective NSAID provides similar rates of symptomatic ulcer recurrence rates as the use of a cyclooxygenase (COX)-2 selective inhibitor. A RCT in high-risk patients with previous ulcer complications supports the additive bene3 t of two risk-reducing strategies, as ulcer complication recurrence was eliminated in high-risk patients who were given a COX-2 selective agent with a PPI. Helicobacter pylori, an independent risk factor for ulcers, should be sought out and eradicated in patients at increased gastrointestinal risk, typically those with an ulcer history. Following H. pylori eradication, however, patients remain at risk and co-therapy with a PPI is recommended. NSAID medication selection should consider both the individual patients' gastrointestinal and cardiovascular risks.

    • "Lansoprazole is a proton pump inhibitor (PPI) drug widely used in the treatment of peptic ulcer disease and other conditions where inhibition of gastric secretion may be beneficial [26], [27]. PPIs are generally well tolerated, and adverse effects are relatively infrequent [28], [29]. Yet, chronic administration of PPIs is becoming increasingly common, and there is a growing concern about potential unexplored adverse effects from such long-term therapy [30]. "

    ABSTRACT: A key event in the pathogenesis of Alzheimer's disease (AD) is the accumulation of amyloid-β (Aβ) species in the brain, derived from the sequential cleavage of the amyloid precursor protein (APP) by β- and γ-secretases. Based on a systems biology study to repurpose drugs for AD, we explore the effect of lansoprazole, and other proton-pump inhibitors (PPIs), on Aβ production in AD cellular and animal models. We found that lansoprazole enhances Aβ37, Aβ40 and Aβ42 production and lowers Aβ38 levels on amyloid cell models. Interestingly, acute lansoprazole treatment in wild type and AD transgenic mice promoted higher Aβ40 levels in brain, indicating that lansoprazole may also exacerbate Aβ production in vivo. Overall, our data presents for the first time that PPIs can affect amyloid metabolism, both in vitro and in vivo.

[27] reported that, in a 6-month treatment period, the proportions of patients who developed upper GI bleeding were 6.4 % in the omeprazole plus diclofenac group and 4.9 % in the celecoxib group (p = 0.60). Lai et al. [28] reported similar results using lansoprazole in a 6-month treatment period (lansoprazole plus naproxen 6.3 % vs. celecoxib 3.7 %, p = 0.37). Chan et al. [29] also reported that the proportions of patients who developed peptic ulcers confirmed by endoscopy at 6 months were 32.3 % in the omeprazole plus diclofenac group and 24.1 % in the celecoxib group (p = 0.15).

    ABSTRACT: As the aging of the population advances, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and/or low-dose aspirin (LDA) is increasing. Their use is accompanied by a risk of serious complications, such as hemorrhage or perforation of the gastrointestinal tract. Therefore, gastroprotective strategies upon the prescription of NSAIDs/LDA are outlined in several guidelines or recommendations. Because all NSAIDs including cyclooxygenase (COX)-2 inhibitors have cardiovascular (CV) toxicity, recent guidelines are based on not only GI risks but also CV risks of NSAID users. Assessment of the adherence to evidence-based guidelines or recommendations for the safe prescription of NSAIDs/LDA in clinical practice is an important issue. Here, we summarize randomized controlled trials (RCTs) on the preventive effects of antisecretory drugs for NSAID- or LDA-induced peptic ulcers. Then, we describe preventive strategies upon the prescription of NSAIDs/LDA outlined in several guidelines or recommendations, and describe studies on adherence and outcomes of adherence to these preventive strategies. Finally, we discuss strategies to increase the adherence rate, and changing pattern of GI events associated with NSAIDs/LDA. In Japan, the preventive strategies upon the prescription of NSAIDs/LDA are expected to spread rapidly because the use of proton pump inhibitors for the prevention of recurrence of NSAID- or LDA-induced peptic ulcers and the use of COX-2 for the palliation of acute pain were recently approved under the national health insurance system. Further studies on adherence to the preventive strategies and the outcomes of adherence, which include both GI events and CV events, in the Japanese population are required.
