Picoprazole is substituted benzimidazole. Picoprazole inhibited the gastric (H+ + K+)-ATPase in a concentration-and time-dependent manner, which may explain its inhibitory action on acid secretion in vitro and in vivo. This compound inhibits acid secretion at the level of the parietal cell by its ability to inhibit the gastric proton pump. Picoprazole affects pepsin secretion probably indirectly via its effect on the parietal cell. Studies on the (Na+ + K+)-ATPase indicated that this enzyme was unaffected by picoprazole.
