From this IVIVC and the requirements
for bioequivalence (AUC0±1: 0.8±1.25 and Cmax : 0.75±1.35; 90% con®dence interval), a speci®cation for dissolution testing in SLS was
calculated as follows: `after 20 minutes, 34±99% dissolved'. Owing to the fact that the rate of absorption in vivo depends on i.a. the
dissolution rate in vivo, it can be concluded that with this speci®cation bioequivalence with respect to both rate of absorption and extent of
absorption is ensured. As this speci®cation is comparable with the USP speci®cation: `not less than 75% dissolved after 1 h', it is concluded
that the USP speci
