 PK Parameters for Bioequivalent Criteria [Regulatives / Guidelines]

Dear Sir,

We have developed Paracetamol Sr 665mg tablets (Unilayer) versus Panadol 665mg tablets (bilayer, 31% IR + 69% SR).

Then what will be the primary PK parameters for Bio-equivalent criteria. Whether Cmax also compulsory to meet Bio-equivalent criteria then what will be the acceptance criteria. OR Only AUC is required as Bio-equivalent criteria?

Regards,

Om Prakash

 PK Parameters for Bioequivalent Criteria

Dear Om Prakash
To state which primary PK Parameters you need you need to know which territory is planned for submission (US, Europe, …).
However in each case you do not only show bioequivalence for Cmax but at least also for AUC (Cmin, partialAUC, … etc.). In General acceptance criteria 80 – 125% unless intraindividual variability allows to widen the acceptance range.

Kind regards and have a nice day

 PK Parameters for Bioequivalent Criteria

Dear Sir,

The European Union guidelines adopted in Australia
Primary PK Parameter: AUC0-t and Cmax
Secondary PK Parameter: Tmax

 Australia’s = EMA’s MR guideline

Hi Muthu Raj,

» The European Union guidelines adopted in Australia
» Primary PK Parameter: AUC0-t and Cmax
» Secondary PK Parameter: Tmax

Here you err. Om Prakash is dealing with a modified-release product. Hence, the respective guideline should be observed (as mentioned by Dan above).

The rise of biometry in this 20th century,
like that of geometry in the 3rd century before Christ,
seems to mark out one of the great ages or critical periods
in the advance of the human understanding.    R.A. Fisher
