Abstract

The aim of this research is to calculate human intestinal permeability in silico and correlate results with those measured in vivo. Optimized human intestinal permeability values were calculated for 16 drugs by de-convolution of human plasma profiles using Parameter Estimation module of SimCYP program V13. Results showed high in silico-in vivo correlation coefficient of 0.89 for drugs with high/low permeability values. In silico permeability, if properly optimized, can be used as surrogate for in vivo permeability for BCS class I drugs and hence is suggested that such methodology could be employed as a support for waiver of in vivo studies.
