RE: Simultaneous vs sequential for modeling parent AND metabolites in pop PK

Hello Alan I have used a sequential approach in the past as the model was more stable with lesser run time.

When you have to develop a pop PK model for both parent and active metabolites, which approach do you prefer or have you used most: simultaneous or sequential? Which way do you think is more scientific? I heard comments saying that the simultaneous approach is not scientific. Thanks, Alan
