Hi John!

❝ Does anyone know if FDA has a guidance on overage of a drug product?

None I'm aware of.

❝ Example, OROS drug products have overage.

Didn’t know that! The NDA of Concerta (01/2000) states in the first label:

Each extended release tablet for once-a-day oral administration contains 18 or 36 mg of methylphenidate HCl USP […]

In the Clinical Pharmacology Biopharmaceutics Reviews we read:

The OROS^® system delivers 18 or 36 mg of methylphenidate HCl […]

So my first idea was that – by design – not the entire dose is released. But in three studies (18 mg, fasting and fed) retrieved capsules were analysed for drug content, which was <1.2%.
So: how much overage have you measured? We have just finished a study with 36 mg; I’ll have a look into the CoAs. :-D

❝ Is there a limit as to how much overage is allowed?

No idea.
