Bioequivalence and Bioavailability Forum

Hi! I would like to get your thoughts on this. During the BE study, while lying in bed or in supine position is Not allowed after drug intake for at least 2 hours, can the volunteer subjects be allowed to stay standing, sitting or walking i.e. limited activity around the room where they stay after dose?

I understand that posture and physical activity of the subjects must be standardized, meals and fluid intake as well, during the study as the bioavailability of an active moiety from a dosage form could be dependent upon GI transit times, posture and physical activity.

I appreciate inputs on the above. Thanks.
