NSAIDs are commonly administered for treatment against inflammatory diseases, gastropatj arthritis, osteoarthritis, dysmenorrhea, and ischemic cerebrovascular disorders [ 5 ]. They concluded that the deficient endogenous PG production is not sufficient to alter intestinal permeability in short term.
This process was also applied to gastric epithelial cells. In the last two decades, new strategies and new drugs have been developed to reduce NSAID-associated upper gastrointestinal GI adverse events. Presently, the most common protective strategies adopted are 1 combination therapy of NSAIDs with gastroprotective agents and 2 use of selective COX-2 inhibitors Table 2. Mostly they are organic acids with pKa in the range of 3—5 [ 5 ].
Salicylate- and aspirin-induced uncoupling of oxidative phosphorylation in mitochondria isolated from the mucosal membrane of the stomach. In gastric juice, they are non-ionized and lipid soluble. Several strategies have been adapted to control the critical side-effects. Under these circumstances, careful prescription should be considered at the individual patient level. Capsule endoscopic examinations revealed that NSAID induced mucosal damages including erosions and ulcerations in small intestines more often than previously expected.
This further leads to occlusion of hastropati microvessels leading to reduced gastric blood flow and release of oxygen-derived-free radicals [ 54 ]. Therefore, the treatment for NSAID-induced small intestinal mucosal injuries should include medications other than conventional acid-reducing agents such as histamine 2 receptor antagonists H 2 RAs and proton pump inhibitors PPIs.
Prostaglandin E prevents indomethacin-induced gastric and intestinal damage through different EP receptor subtypes. View at Google Scholar M.
Patients taking aspirin represent a real challenge for treatment, since interaction with frequently prescribed NSAIDs e.

In this paper, the mechanism of action of NSAIDs and their critical gastrointestinal complications have been reviewed. Published online Feb Di Matteo, and A. Abstract Non-steroidal anti-inflammatory drugs are the most commonly prescribed drugs for arthritis, inflammation, and cardiovascular protection.
However, no signs of improvement were observed in cases of gastric bleeding, [ 62 ] gasyropati hence, these drugs are no longer recommended presently.
However, long-term administration of NSAIDs causes adverse gastrointestinal GI symptoms including mucosal lesions, bleeding, peptic ulcer, nsad inflammation in intestine leading to perforation, strictures in small and large intestines, leading to chronic problems [ 9 — 11 ]. Conclusion This review is focused on the pathophysiology of NSAID-induced gastroenteropathy, especially on PG-independent, mitochondria-dependent small intestinal injury.
Current Perspectives in NSAID-Induced Gastropathy

Non-steroidal anti-inflammatory drug gastropathy: causes and treatment.
NSAIDs were absorbed into the enterocytes, and uncouples the mitochondrial oxidative phosphorylation. However, recent clinical demonstrated the prevalence of non-steroidal anti-inflammatory drugs-induced small intestinal mucosal injury is more often than previously expected. Adams Nsald, Cobb R. The latter is also connected to a lipophilic part through a polar group. However, they cause gastrointestinal complications.
The difference in aggressive factors of mucosal epithelium may affect the pathophysiology of NSAID-induced mucosal injury: ROS from mitochondria play an important role in the release of cytochrome c and other pro-apoptotic proteins, which can trigger caspase activation and apoptosis. gastropzti

Generated ROS from activated neutrophils results in the mucosal damage, the finding experimentally confirmed that the prevention of neutrophil infiltration by induction of neutropenia inhibited NSAID-induced macroscopic mucosal damage.
The mechanism of NSAID-induced mucosal injury that is not dependent with systemic PG deficiency includes local injuries of these agents. Mucous and bicarbonate are secreted by gastropaati epithelial cells. COX-2 inhibitors are gaxtropati with fewer upper GI side effects, however, they are not as symptom free as hoped and still place people at risk of gastroduodenal mucosa injury.
