 FDA guide methylphenidate oral ER tablet - subject-by-formulation has gone? [Regulatives / Guidelines]

Hy!

Brand new FDA guideline on methylphenidate

https://www.fda.gov/downloads/Drugs/GuidanceComplianceRegulatoryInformation/Guidances/UCM581432.pdf

...apparently they skipped this "subject-by-formulation" part of the thing...

Hi No-wan kenobi,

» ...apparently they skipped this "subject-by-formulation" part of the thing...

What??!!!??! Are you seriously saying someone applied some degree of common sense in the guidance??

I could be wrong, but…


Best regards,

No, I still don't believe much in the usefulness of IVIVCs for OIPs when it comes to picking candidate formulations for the next trial. This is not the same as saying I don't believe in IVIVCs.

Yes for Ritalin SR. I've said it many times to people. That Sub-by-form interaction testing part is really only applicable to Concerta! If one tried to make sense of it.
