What is an NSAID? Nonsteroidal Anti-inflammatory drug. In this paper, the mechanism of action of NSAIDs and their critical gastrointestinal complications have been reviewed. This paper also provides. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most highly prescribed drugs to decrease NSAID-induced GI damage including use of.

The Expert Consensus Report has been prepared taking into account the potential risks and benefits from simultaneous intake of PPIs and thienopyridines. PG is one of the main mediators of inflammation, pain, and fever and is synthesized from arachidonic acid.
The important role of bile acid an aggravating factor of NSAID-induced small intestinal injury was suggested by the result of an in vivo study that gastorpati duct ligation reduced the prevalence of the lesions significantly.
This paper also provides the information on different preventive measures prescribed gastorpati minimize such adverse effects and analyses the new suggested strategies for development of novel drugs to maintain the anti-inflammatory functions of NSAIDs along with effective gastrointestinal protection. In human stomach, little or no COX-2 protein and activity gastropatk demonstrated, while abundant COX-1 protein and activity was demonstrated.
As a result, hastropati pH at the surface of gastric mucosal epithelial cells normally is maintained in the neutral range when the pH at the gastric luminal surface reaches 1 to 2. Other treatment options include misoprostol which is a synthetic prostaglandin designed to replace those loss by NSAIDs. Safe NSAID prescription should be straightforward since the most relevant aspects are clinical in nature.
Current Perspectives in NSAID-Induced Gastropathy
Further studies have demonstrated the role of recombinant human lactoferrin in decreasing acute NSAID-induced GI bleeding and reduction of gastric ulcers . NSAIDs inhibit the enzyme cyclooxygenase which is a necessary enzyme for the synthesis of prostaglandins from arachidonic acid. COX-1 is constitutively expressed in most of tissues including stomach and responsible for maintaining gastric mucosal integrity at base line, whereas COX-2 participates in inflammation.
A potential complication of ulcers left untreated is that the ulcer can perforate through the stomach mucosa and cause infection to spread or the ulcer can erode stomach arteries creating a life-threatening bleed. For those at the highest risk, a combination of PPI plus a coxib is the best option.
NSAIDs are generally chiral gastropwti except diclofenacbut mostly a single enantiomer is pharmacologically active [ 26 ]. Author information Article notes Copyright and License information Disclaimer.
In most cases Physiopedia articles are a secondary source and so should not be used as references. Clinically significant intestinal toxicity is also recognized but less clearly defined.
Leukotrienes cause inflammation and tissue ischaemia leading to gastric mucosal injury [ 5152 ].
Capsule endoscopic examinations revealed that NSAID induced mucosal damages including erosions and ulcerations in small intestines more often than previously expected. Further reports have shown that C-lobe of lactoferrin can also bind to COXspecific drugs and produce observable effects against gastric inflammation and bleeding [ ].
PGs play a key role in gastric epithelial defense by enhancing the pre-epithelial, epithelial, post-epithelial defense mechanisms: Use of these drugs in certain types of cancer treatment has also been reported recently [ 67 ].
In these pathophysiological processes, the NSAID-induced inhibition of oxidative phosphorylation in mitochondria is considered as the main underlying mechanism.

The therapeutic effects of NSAIDs have made these drugs extremely popular against inflammatory disorders for the past several decades.

Contents Editors Categories Share Cite. Therefore, safe prescription is mandatory in order to prevent adverse events. This led to the development of new therapeutic drugs: Recent insight into the mechanism of gastrointestinal tract ulceration. PPIs are found to be effective in reducing the risk of GI bleeding in such patients [ 23 ]. National Center for Biotechnology InformationU. The inflammation Once the intestinal barrier has been broken, the sequence of events leading to inflammation is determined by the luminal aggressive factors.
Prevention and Treatment of NSAID Gastropathy.
However, these methods also have limited potency because of their additional cardiovascular effects [ 16 — 19 ]. Along with this, there is also enhanced production of proinflammatory mediators such as tumour necrosis factors [ 53 ].
Robert A, Asano T. Gastric gastgopati apoptosis in guinea pig gastric mucosal cells in primary culture. NSAID induced gastropathy can result in stomach or duodenal ulcers which may even lead to death. This uncoulping causes dysfunction of the tight intracellular junctions and increases the intestinal permeability.
PPIs are generally prescribed for long-term use since they do not show any significant risk of any associated effects [ 6364 ]. View at Google Scholar W. The most common symptom is heartburn but those with GERD can also have a dry cough, asthma-like symptoms, and trouble swallowing.

The mechanism of NSAID-induced mucosal injury that is not dependent with systemic PG deficiency includes local injuries of these agents. NO aspirin has been found to impart an increased antithrombotic potency compared with conventional aspirin .
In the last two decades, new strategies and new drugs have been developed to reduce NSAID-associated upper gastrointestinal GI adverse events. In gastric juice, they are non-ionized and lipid soluble. Gastroduodenal mucosal injury in patients taking low-dose aspirin and the role of gastric mucoprotective drugs: It has been found to preferentially inhibit COX-2 but exhibited the anti-inflammatory, antipyretic, and analgesic activities of NSAIDs [ 869394 ].
This article has been cited by other articles in PMC. Therefore, it is essential that health care professionals assess each patient’s risk factors and recommend either discontinued use of an NSAID or inclusion an accompanying cytoprotectant agent in those patients considered high risk.
However, based on some reports suggesting possible interactions between PPIs and thienopyridines [ 2324 ], the expert guidelines have been further updated in [ 25 ].
