Web(4)The BCS sorts compounds into four classes based on high/low permeability and solubility, in which BCS class 1 represents highly permeable and highly soluble compounds that will be well-absorbed after oral administration. In contrast, class 4 compounds have both low solubility and low permeability. Webpermeability classification is difficult to define as it depends on the individual assay variability. Inter-lab variability is considered high and potential sources of variability have been described (Volpe, J Pharm Sci (97), 2008;(Lee et al, Eur J Pharm&Biopharm (114), 2024). However, inter-lab variability is substantially lower for BCS lds john 15 https://zemakeupartistry.com
