The Irrelevance of In Vitro Dissolution in Setting Product Specifications for Drugs Like Dextromethorphan That are Subject to Lysosomal Trapping

The purpose of the present study was to develop a physiologically based pharmacokinetic model for dextromethorphan (DEX) and its metabolites in extensive and poor metabolizers. The model was used to study the influence of dissolution rates on the sensitivity of maximum plasma concentration and area...
