Abstract:

The paper presents the results of in vitro dissolution testing for oral solid dosage forms containing three representative oxicams in blank or standard, fast and fed state simulated intestinal fluids (FaSSIF/FeSSIF). Non-compendial PeakTM vessel were used in combination with an adapted composition of biorelevant media (1:2 dilution with the corresponding aqueous buffer system). The results revealed a significant contribution of the improved stirring profile to the release process in FeSSIF, counterbalancing the decreased concentration of endogenous tensioactive compounds. The dissolution efficiency was comparable for the two blank media. The implemented changes in composition of the biorelevant media and experimental design leaded to comparable variability of data, but
request further evaluation of the discriminatory character for internal, formulationcontrolled factors.
