APPARATUS 2 Figure 1 Particle Sciences 2010 Particle Sciences, Inc. All rights drug substance and involves two steps: Dissolution and absorp-tion (or permeability). Understand-ing the multi-step Dissolution pro-cess is essential to proper in Vitro method development. Dissolution is the process of extracting the API out of the Dosage form Solid -state matrix into solution within the gastrointestinal tract. Absorption is the process of transporting the drug substance from the gastroin-testinal lumen into the systemic circulation. Dissolution Testing is an in vi-tro method that characterizes how an API is extracted out of a Solid Dosage form.
the USP recommended ionic strength.5 For APIs that exhibit low solubilities in aqueous me-dia throughout the pH range, the addition of surfactants is recom-mended.
