title: [Dissolution determination in the rotating flask model. Effect of rotation rate and fluid volume on the solubility determination of standard test tablets in the Resotest dissolution tester].
abstract: The influence of two important factors, the rotational speed and the fluid volume within the system, on the release characteristics of prednisone-test tablets in the rotating flask dissolution-tester (Resotest-apparatus after Koch) has been investigated. As a result, standard conditions for dissolution experiments with the rotating flask model, i.e. a mean rotation number of 30 r.p.m. and an actual fluid volume of 500 ml, are proposed.
