WebOct 1, 2024 · A similar procedure was used for FeSSIF-v2, of which a blank buffer composed of sodium hydroxide (0.16 g), maleic acid (0.32 g), and sodium chloride (0.37 g) was adjusted to pH 5.8 with sodium hydroxide (1 N). FeSSIF v2 powder (0.49 g) was added to 25 ml of blank buffer. Both FaSSIF and FeSSIF solutions were stirred to dissolve the … WebIn comparison with the surfactant solutions or blank buffers, these media are able to better reflect the physiological solubility and dissolution behavior of poorly soluble active pharmaceutical ingredients (APIs). The aim of this investigation was to review the composition of FaSSIF and FaSSIF-V2 according to recently summarized data about the ...
