Core Tip

Core tip: The herbal preparation STW 5, clinically used in functional dyspepsia and irritable bowel syndrome, was compared to omeprazole in protecting against diclofenac- induced gastro-duodenal lesions in rats. Both drugs were effective in preventing changes in the level of inflammatory mediators (tumor necrosis factor α, interleukins-1β and 10), in the level of the oxidative stress enzyme, heme oxygenase-1, and the apoptotic regulator (B-cell lymphoma 2) in both stomach and duodenum. However, STW 5 was more effective than omeprazole in protecting against the histological damage. The results emphasize the potential usefulness of STW 5 and its superiority over omeprazole in protecting against gastro-duodenal lesions induced by nonsteroidal anti-inflammatory drugs.
