The protective effect of benfotiamine on gastric ulcers in male rats: an experimental study

Gastric ulcers are a common gastrointestinal disorder associated with significant morbidity and mortality. It can also increase the risk of gastric cancer. This study aimed to investigate the effect of benfotiamine on experimentally-induced gastric ulcers in male rats. In this study, 30 Wistar male rats were divided randomly into six groups: control (normal), indomethacin, omeprazole, and treatment groups, including 50, 100, and 200 mg/kg of benfotiamine. Gastric ulcer was induced by indomethacin gavage. Omeprazole and different therapeutic doses of benfotiamine were administered for three days. Twenty-four hours after the last treatment, the rats were euthanized, and samples were collected.

The results demonstrated that 100 and 200 mg/kg of benfotiamine treatment significantly improved indomethacin-induced gastric tissue damage. Moreover, benfotiamine at 100 and 200 mg/kg effectively attenuated the levels of pro-inflammatory cytokines IL-6 and TNF-α and oxidative stress markers MDA and ROS while increasing the antioxidant GSH. These findings suggest that benfotiamine’s gastroprotective effects are mediated through its antioxidant and anti-inflammatory properties, which help mitigate the tissue damage and inflammatory response associated with indomethacin-induced gastric ulcers.

However, further research is needed to elucidate the precise molecular mechanisms underlying these beneficial effects and to evaluate the potential therapeutic application of benfotiamine in clinical settings.
