The effect of ketoprofen lysine salt on mucosa of rat stomach after ethyl alcohol intoxication

Introduction: Ketoprofen is a commonly used nonsteroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic properties. Side effects of ketoprofen occur mainly from the gastrointestinal tract due to the inhibition of cyclooxygenaze-1. Binge drinking at least once a week is reported by 80 million Europeans. On the day after many of them use NSAIDs. This increases the risk for damage of gastric mucosa. Aim: The aim of the study was to check if use of ketoprofen lysine salt (KLS) has any gastroprotective effect on mucosa of rat stomach after ethyl alcohol intoxication. Materials and methods: There were 6 groups of 6 male rats which received: 1. ethanol; 2. 0.9% NaCl; 3. 0.9% NaCl and ketoprofen; 4. ethanol and ketoprofen; 5. 0.9% NaCl and KLS; 6. ethanol and KLS. Results: In groups 1, 2 and 3 the histopathologic examination of the stomachs revealed normal picture, without signs of inflammation. In the group 4, 5 and 6 within the mucosa and submucosa there were visible numerous infiltrates of inflammatory cells, consisting mainly of lymphocytes, plasmocytes and eosinophilia. Total leukocyte count was elevated in group 3, 4, 6. There was a significant decrease of blood urea concentration in group 6 vs 2 and significant decrease of serum albumin in group 6 vs 1 and 2, and total protein vs group 1. Conclusion: Side effects of ketoprofen occur mainly from the gastrointestinal tract. KLS has no gastroprotective effect after ethanol-gastric injury and does not protect gastric mucosa from damage produced by binge drinking. Therefore it should not be used after drinking distilled spirits.

Automated summary

Ketoprofen is a commonly used NSAID with side effects mainly occurring in the gastrointestinal tract, and it does not have a gastroprotective effect on the stomach mucosa after ethanol-induced injury.
