Its for EMEA.

Not BE, but comparative BA. You can only hope for similar extent of absorption but never for rate of absorption in a comparison of ER vs IR. Furthermore, BE means similarity in PK metrics of interest if equimolar doses are administered. Sometimes one has to increase the ER dose to get similar AUCs… Whatever is applicable in your case, BE is the wrong term.


Can you please elaborate to understand. If you can provide me any supportive literature to go in detail its really helps me.
