CS-526 is a potent, selective, reversible and orally active acid pump antagonist. CS-526 inhibits H+,K+-ATPase activity. CS-526 inhibits gastric acid secretion and prevents esophageal lesions. CS-526 has the potential for the research of gastroesophageal reflux disease[1]. | [in vivo]
CS-526 (1, 3, 10, 30 mg/kg; intraduodenal or p.o.) inhibits gastric acid secretion in a dose-dependent manner in pylorus-ligated rats[1].
CS-526 (1, 3, 10, 30 mg/kg; intrapouch; 180 min) dose-dependently inhibits the histamine-induced gastric acid secretion in the Heidenhain pouch dogs[1].
CS-526 (1, 3, 10, 30 mg/kg; intraduodenal or p.o.) prevents esophageal lesions and acute gastric mucosal lesions[1]. Animal Model: | Pylorus-Ligated Rats[1] | Dosage: | 1, 3, 10, 30 mg/kg | Administration: | Intraduodenal administration or p.o. | Result: | Dose-dependently inhibited gastric acid secretion with ID50 values of 2.8, 0.7 mg/kg for intraduodenal administration and oral administration, respectively. |
Animal Model: | Reflux Esophagitis Model in Rats[1] | Dosage: | 1, 3, 10 mg/kg | Administration: | Intraduodenal administration or p.o. | Result: | Significantly reduced the lesion scores with ID50 values of 5.4, 1.9 mg/kg for intraduodenal and p.o. respectively. |
