Abstract
Dissolution profiles in 0β1N hydrochloric acid using both the paddle stirrer apparatus and the spin filter apparatus were obtained for prednisone tablets made by seven different manufacturers and prednisolone tablets made by eight different manufacturers. Dissolution parameters were correlated with results obtained in three human bioavailability trials which were previously reported. Also, results obtained in one apparatus were correlated with those obtained in the other apparatus. Such correlations may be useful in the setting of in vitro dissolution rate specifications for commercial prednisone and prednisolone tablets.

The object of the study was to develop an oral dosage form of aminorex which would produce prolonged, stable plasma levels of total drug. Since no definite set of dissolution conditions exists for the evaluation of the in uiuo availability of a given drug, an arbitrary set of dissolution conditions
This article considers the in vivo significance attached to in vitro dissolution testing. Almost invariably, the in vitro dissolution test is interpreted in terms of bioequivalence. The literature that describes methods for setting in vitro dissolution specifications is reviewed. The most common int
