Hi everyone, Some dosage forms like buccal tablets, rectal suppositories are not listed in Table -1 and 2 of Compliance Policy for the Quantity of Bioavailability and Bioequivalence Samples Retained Under 21 CFR 320.38(c). However as per note:11, can we proceed for minimum sample retention quantity of 30 units each for test and reference products? Thanks in advance Edit: Guidance linked. [Helmut] |

Hi Vuas, ❝ … can we proceed for minimum sample retention quantity of 30 units each for test and reference products? See lines 63–65: 21 CFR 320.38(c) requires that applicants retain reserve samples of the test product and reference standard used in a BA or BE study that consist of a sufficient quantity to perform five times all the release tests required in the application or supplemental application. (my emphasis)If your test requires six units, 30 are fine. See also the guidance Handling and Retention of BA and BE Testing Samples.

But for vaginal suppositories retention is given 30 units so we did studies with retention of 30 for rectal suppositories as well. Edit: Full quote removed.
