体内研究 |
Pumaprazole is a reversible proton pump antagonist.Basal acid secretion in the Ghosh-Schild rat is inhibited by Pumaprazole with a higher efficacy compare to ranitidine.Pumaprazole displays identical ID50 values on day 1 (11μmol/kg,95% confidence limits of 5 and 23) and on day 7 (10μmol/kg,95% confidence limits of 4 and 23) of a repeated dose study in this model.The lower dose of Pumaprazole (27μmol/kg) rapidly elevates luminal pH up to almost neutrality,the higher dose (54μmol/kg) further prolongs this pH-elevating effect. |
推荐实验方法(仅供参考)
动物实验: |
|
The pylorus of female Sprague-Dawley rats (160 to 220g body weight) is ligated under ether anesthesia,the abdomen is closed and 100mg/kg of acetylsalicylic acid (ASA) in 10mL/kg are given orally.Following ASA administration,Pumaprazole (solution) or vehicle (i.v.saline or tap water in case of oral administration) is given i.v.in 1mL/kg or i.d.in 2.5mL/kg.Oral drug administration (in 10mL/kg) is 1h before pylorus ligation.Four hours after pylorus ligation,the stomach is excised,carefully keeping the esophagus closed,opened along the greater curvature and the luminal contents are removed,centrifuged,the volume is measured and the acidity determined by titration with 0.1 N NaOH to pH 7. |
本计算器可帮助您计算出特定溶液中溶质的质量、溶液浓度和体积之间的关系,公式为:
质量 (g) = 浓度 (mol/L) x 体积 (L) x 分子量 (g/mol)
