RegisterIn-vitro Dissolution complementary to BE [Regulatives / Guidelines]
Dear members,
Probably this is an old issue for most of you... The EMEA guideline on the investigation of BE states that "Similarity of in vitro dissolution should be demonstrated at all conditions within the applied product series, i.e. between additional strengths and the strength(s) (i.e. batch(es)) used for bioequivalence testing."... What about the QC dissolution method.... what I mean to ask is: would an in-vitro dissolution in SGF media, reflect bioequivalency if the three different buffers (pH 1.2, 4.5 and 6.8) demonstrated otherwise.
Also, some lectures state to conduct in-vitro dissolution profiles under similar conditions... does that mean within a certain period of time... can't I compare my current data against results from 2 years ago... Would that raise questions by regulatory authorities.
Apologies if such questions are depressingly not challenging for you, nevertheless, thank you for your comments...
