| In vivo | Dalcotidine (10-50 mg/kg x 2/day; oral; rats)markedly promoted the well-balanced healing of gastric ulcers, as evidenced by the reduction of ulcers, regeneration of mucosa and proliferation of connective tissue. Dalcotidine caused an increase in gastric mucus secretion in the regenerated mucosa around the gastric ulcers. Dalcotidine is characterized by a potent promoting action on the healing of chronic ulcers, suggesting that the increase in gastric mucus secretion might be associated with the antiulcer actions of Dalcotidine in part.[2] |
