In vitro experiments demonstrate that the dissolution rates of both the ionizable compounds used in this study were slower in bicarbonate buffer than in phosphate buffer, with the same buffer concentration, because of the lower interfacial buffer capacity, a unique behavior of bicarbonate buffer. ...
The systematic shift in profiles, particularly with buffer capacity, underlines the sensitivity of IVIV relationship to medium composition and hence the current difficulties in making a rational choice of an appropriate single dissolution medium. 展开 关键词: Ketoprofen Dissolution Buffer capacity In ...
•The buffering capacity of a solution works best when the pH is near the pK a pK a or pK b •pK a = - log K a •pK b = - log K b Buffer Problems •Calculate the pH of a solution containing 0.10 M HAc in 0.10 M ...
