| Description | Pumaprazole (BY-841) is an antagonist of a reversible proton pump. | 
| In vivo | Pumaprazole shows identical ID50 values on day 1 (11 μmol/kg, 95% confidence limits of 5 and 23), and on day 7 (10 μmol/kg, 95% confidence limits of 4 and 23) of a repeated dose study in this model. Basal acid secretion in the Ghosh-Schild rat is inhibited by Pumaprazole with a higher efficacy compared to ranitidine. The lower dose of Pumaprazole (27 μmol/kg) rapidly elevates luminal pH up to almost neutrality, the higher dose (54 μmol/kg) further prolongs this pH-elevating effect[1]. |
