Abstract Non-steroidal anti-inflammatory drugs are the most commonly prescribed drugs for arthritis, inflammation, and cardiovascular protection.
In this regard, development of such new molecules that can sequester the unbound drug molecules is essential for addressing the NSAID-related GI damage.
Licofelone imparts significant analgesic and anti-inflammatory effects without any GI side-effects as observed in animal models [ ]. It is suggested that NSAIDs cause membrane permeabilization leading to disruption of epithelial barrier [ 46 ].
Nsair study in vitro using gastric RGM1 cells also confirmed that indomethacin treatment induced a decrease of mitochondrial transmembrane potential and induced apoptotic protein activations cleaved caspase 3 and 9which gasteopati inhibited by an antiulcer drug rebamipide Fig.
COX-1 is constitutively expressed and is responsible for the normal physiological protection of gastric mucosa. The acidic moiety is essential for COX inhibitory activity and is linked to a planar, aromatic group. Further clinical trials are in progress in osteoarthritis patients [ ]. Aspirin and non-aspirin non-steroidal anti-inflammatory drugs NSAIDs almost invariably cause acute gastroduodenal injury and probably account for approximately 12, ulcer bleeding episodes and deaths per annum in the United Kingdom.
Conclusion This review is focused on the pathophysiology of Naaid gastroenteropathy, especially on PG-independent, mitochondria-dependent small intestinal injury.
NSAIDs were also able to induce both necrosis and apoptosis in gastric mucosal cells [ 47 ]. Subscribe to Nsaod of Contents Alerts. By far, celecoxib and rofecoxib stand out as the most effective COX-2 inhibitors and show efficacy over nonselective NSAIDs in regard to GI complications including mucosal lesions and other adverse GI symptoms [ 8687 ]. Control of activity states of heart mitochondrial ATPase. Thus, there is no drug yet formulated that can avert the potential side-effects completely.
Crohn’s Disease is a type of inflammatory bowel disease which causes the gastrointestinal tract to be chronically inflammed. It seems that the gastorpati of pathophysiology of NSAID-induced mucosal injury may differ in stomach and in small intestine.
A number of strategies have been recommended by American College of Gastroenterology to decrease NSAID-induced GI damage including use of selective cyclooxygenase-2 inhibitors, coadministration of gastroprotective agents like misoprostol, PPIs, or histamine-2 receptor antagonists [ 20 ].
However, they cause gastrointestinal complications.
J Clin Biochem Nutr. Cryer B, Spechler SJ. Lansoprazole protects and heals gastric mucosa from non-steroidal anti-inflammatory drug NSAID -induced gastropathy by inhibiting mitochondrial as well as Fas-mediated death pathways with concurrent induction of mucosal cell renewal.
View at Google Scholar J. More recently, experimental data in animal demonstrated that for gastric ulceration to occur, both COX-1 and COX-2 must be inhibited. Non-steroidal anti-inflammatory drugs NSAIDs such as aspirin and indomethacin are the most commonly prescribed drugs for arthritis, inflammation, and cardiovascular protection. Other Synonyms of the Category: Mitochondria, lipid peroxidation, and apoptosis A mitochondrion is a membrane-enclosed organelle with 0.
Mitochondria, oxidative stress and cell death. The inflammation Once the intestinal barrier has been broken, the sequence of events leading to inflammation is determined by the luminal aggressive factors. Effect of salicylic acid and calcium on mitochondrial functions. Salicylate- and aspirin-induced uncoupling of oxidative phosphorylation in mitochondria isolated from the mucosal membrane of the stomach.

Animal data suggest that polymorphonuclear leukocytes PMNs are important for acute damage though the relevance to humans has yet to be established. Omeprazole was followed by other PPIs like lansoprazole, pantoprazole, rabeprazole, and so forth [ 66 ].
This process was also applied to gastric epithelial cells. PGs play a key role in gastric epithelial defense by enhancing the pre-epithelial, epithelial, post-epithelial defense mechanisms: Under these circumstances, careful prescription should be considered at the individual patient level.
Prostaglandins in the gastric system help maintain gastric blood flow, increase bicarbonate naid, and increase mucus that serves as a protective barrier against bacteria colonization and mechanical injury.
NSAIDs are commonly administered for treatment against inflammatory diseases, rheumatoid arthritis, osteoarthritis, dysmenorrhea, and ischemic cerebrovascular disorders [ 5 ]. Aspirin and NSAIDs act by inhibiting prostaglandin synthesis catalysed by two cyclooxygenase enzymes.
Current Perspectives in NSAID-Induced Gastropathy
Some of these potent drugs have even been withdrawn [ ]. It has been found to preferentially inhibit COX-2 but exhibited the anti-inflammatory, antipyretic, and analgesic activities of NSAIDs [ 869394 ]. Use case Healthcare Patents Pharma Others.

H2-receptor antagonists and proton pump inhibitors PPIs are most commonly used because they not only reduce acid secretion but also enhance gastric pH and have a role in scavenging-free radicals [ 5859 ]. Therefore, safe prescription is mandatory in order to prevent adverse events.
Further studies have demonstrated the role of recombinant human lactoferrin in decreasing acute NSAID-induced GI bleeding and reduction of gastric ulcers .
Scand J Rheumatol Suppl. The mechanisms that the inhibition of oxidative phophorylation increases intestinal permeability are not well understood, but are explained as follows:
