 Concerta individual profiles [Study Per­for­mance]

Concerta is a well-known modified release formulation of methylphenidate. Routinely one sees mean plasma concentration time information from studies in the literature. I am looking for a reference to a publication where individual plasma concentration information is reported either as individual profiles or individual plasma concentration time values. My interest lies in the variability in individual profile shape.

Hi Angus,

» I am looking for a reference to a publication where individual plasma concentration information is reported either as individual profiles or individual plasma concentration time values.

I don’t know any… Maybe John can help?

» My interest lies in the variability in individual profile shape.

To give you an idea, one of mine (18 male subjects, Concerta 36 mg, fed state [normal breakfast]; d-MPH base by enantio­selective GC/MS, LLOQ 49 pg/mL):

Helmut: Thank you. Your data set as a spaghetti plot looks quite good, but it is difficult to find individual data sets.

I know. Sorry, I can’t disclose subjects’ data.
