Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit the synthesis of prostaglandins and thereby make the stomach more susceptible to injury. [2] Gastric cytoprotective drugs include carbenoxolone , deglycyrrhizinised liquorice , sucralfate (aluminium hydroxide and sulphated sucrose ), misoprostol (a prostaglandin analogue), bismuth chelate ...
The gastric mucosal barrier is the property of the stomach that allows it to safely contain the gastric acid required for digestion. If the barrier is broken, as by acetylsalicylic acid (ASA, aspirin) in acid solution, acid diffuses back into the mucosa where it can cause damage to the stomach itself.
An estimated 10–20% of NSAID patient's experience dyspepsia, and NSAID-associated upper gastrointestinal adverse events are estimated to result in 103,000 hospitalizations and 16,500 deaths per year in the United States, and represent 43% of drug-related emergency visits. Many of these events are avoidable; a review of physician visits and ...
An enteric coating is a polymer barrier applied to oral medication that prevents its dissolution or disintegration in the gastric environment. [1] This helps by either protecting drugs from the acidity of the stomach, the stomach from the detrimental effects of the drug, or to release the drug after the stomach (usually in the upper tract of the intestine). [2]
Aspirin "weakens the stomach's protective lining against stomach acid, making the stomach and intestines more vulnerable to ulcers, which can bleed," according to Harvard Health.
Prostaglandin inhibitors are drugs that inhibit the synthesis of prostaglandin in human body. [1] There are various types of prostaglandins responsible for different physiological reactions such as maintaining the blood flow in stomach and kidney, regulating the contraction of involuntary muscles and blood vessels, and act as a mediator of inflammation and pain.
NSAIDs inhibit cyclooxygenase-1, or COX-1, an enzyme responsible for the biosynthesis of eicosanoids in the stomach, which increases the possibility of peptic ulcers forming. [21] [22] [23] Also, NSAIDs, such as aspirin, reduce a substance that protects the stomach called prostaglandin. These drugs used in a short period are not typically ...
Long-term use of NSAIDs can cause gastric erosions, which can become stomach ulcers and in extreme cases can cause severe haemorrhage, resulting in death. The risk of death as a result of GI bleeding caused by the use of NSAIDs is 1 in 12,000 for adults aged 16–45. [5] The risk increases almost twentyfold for those over 75. [5]
