Comparison of the ulcerogenicity of indomethacin and the gastric secretion in verapamil-treated rats.
The authors studied the effect of different doses of verapamil on the ulcerogenic activity of indomethacin (20 mg.kg-1) in rats. This was compared with the effect of verapamil on total gastric juice secretion, the amount of acid and the pH. It was found that, as distinct from total secretion and the amount of HCl, which verapamil reduced in correlation to the dose, ulcerogenicity after indomethacin was inhibited the most by a dose of 10 mg.kg-1 verapamil. Larger doses (20 and 30 mg.kg-1) did not increase the anti-ulcerogenic effect any further. This implies that verapamil-induced inhibition of the ulcerogenicity of indomethacin is not related directly to inhibition of total and acid gastric juice secretion.
