Protective Effect of Piperine on Indomethacin-Induced Intestinal Damage

Area of Science:

• Pharmacology
• Gastroenterology
• Microbiology

Background:

• Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for pain and inflammation.
• Chronic NSAID use can lead to significant gastrointestinal adverse events, including damage to the gastric mucosa and small intestine.
• Investigating natural compounds for protective effects against NSAID-induced toxicity is crucial.

Purpose of the Study:

• To evaluate the protective potential of piperine against indomethacin-induced intestinal damage in a mouse model.
• To assess the impact of piperine cotreatment on biochemical markers, histopathology, and intestinal microbiota composition.
• To determine if piperine can mitigate NSAID-associated gastrointestinal side effects.

Main Methods:

• Male Mus musculus mice were administered indomethacin to induce intestinal damage, with a cotreatment group receiving piperine.
• Intestinal inflammation was assessed via macroscopic, histopathological, and metagenomic analyses.
• Biochemical serological analysis, including aspartate aminotransferase (AST) levels, and micronucleus formation were evaluated.

Main Results:

• Piperine treatment significantly reduced small intestine inflammation and necrosis in the large intestine.
• Histopathological analysis revealed increased crypt and villus measurements in the piperine-treated group.
• Piperine cotreatment led to increased intestinal genus diversity, a reduction in micronucleus formation, and normalized AST levels compared to indomethacin alone.

Conclusions:

• Piperine demonstrates significant potential in mitigating NSAID-induced intestinal damage.
• Cotreatment with piperine offers a protective effect against gastrointestinal toxicity associated with NSAIDs.
• Piperine may serve as a valuable adjunct therapy to reduce the adverse effects of chronic NSAID use.
