Papp value permeability
WebJan 24, 2012 · Rh123 is a known ABC-transporter P-glycoprotein substrate. 19 Therefore, a net compound efflux should be seen when comparing Papp values for B-to-A transport to Papp values for A-to-B permeability. Apparent permeability values for A-to-B Rh123 movement, similar to LY, were low using the automated method. WebThe objective of this study was to investigate the relationship between in vitro permeability (Papp) values obtained from isolated nasal tissues and the absorption rates (ka) of the same compounds following nasal administration in animals and humans. The Papp of a set of 11 drug compounds was measur …
