 BCS for Extended-release Formulations [Dissolution / BCS / IVIVC]

Good morning Europe!

Anyone aware of the state of the BCS as it concerns extended-release formulations? Is there any regulatory movement on this?

Can someone suggest any good articles that deals with the BCS and extended-release formulatons?

Thank you.

By definition the BCS is only applicable to immediate relase formulations. Or to be more precise: For IR products marketing authorization may be granted based on in vitro studies alone. If it comes to MR-formulations, you will need to perform at least one conventional in vivo study, and may apply for biowaivers for different strenghts - given the conditions in guidelines (proportionality of contents of API, excipients, etc.).

 BCS for Extended-release Formulations

Good afternoon!

The WHO Technical Report Series 937 specifies in Annex 7, sections 9.3.3.2 - 9.3.3.4 the requirements for biowaivers in the cases of delayed-release and extended-release tablets and capsules. However, it is not clear to me whether these specifications would be accepted by EMA. Have somebody any experience in this field?
