Γειά σου κανείς & Outlaw Torn,

❝ If both (T and R) are solutions (not suspensions) and exhibit no excipients influencing absorption, no need for BE (or BCS biowaiver), in my opinion.

I agree. Sometimes the API tastes terrible (e.g., bitter) and a lot of excipients are added to mask it. Mannitol is not unusual (as a sweetener and to increase viscosity). Then you would be out of the game ⇒ in vivo study.
If not, dissolution testing is possible but technically demanding.

❝ OT: How to get this cool little EU-flag in the "latest posts" overview on the forum? Do you have an EU-IP or how does this work?

The IP geolocation (under ) used in the forum is only ~98% accurate. The commercial product (99.8% accurate) would cost more than my entire domain & webspace. No way.
As of today 0.44% of posts are located in the . Might be false positives. Duno.

❝ Not sure about the flag thing (I can't see any flags);

There.
