AUC passes, Cmax fails: biopharmaceutical difference [PK / PD]
Merhaba akif,
Only if your drug is in BCS class I or – under certain conditions – in class III, dissolution plays a major rule. If in class II/IV, dissolution is not predictive. There are a manifold of reasons with the absorption rate differs between products. Even if excipients and their amount are identical, differences in the manufacturing process may explain the different absorption.
No.
Only if you have problems with a “first point Cmax”.
No.
❝ I want to know that why while auc with in spect Cmax out of it? its means that test has higher dissolution rate everytime, …
