Fw: calculation of AUC

I second Bill's suggestion to work this out on your own for your specific problem. This forum can help you with general questions and overall approaches, but very specific queries like this are for you and your colleagues to hash out. ----- Forwarded by Michael J Fossler/PharmRD/GSK on 03/20/2009 09:40 AM ----- "Bill Bachman" <bachmanw Sent by: owner-nmusers 20-Mar-2009 09:17 To "'Martin Bergstrand'" <martin.bergstrand <ethan.wu75 cc Subject RE: [NMusers] calculation of AUC The easiest answer is to work it out. Do some simulations (without variability) with multiple subjects with identical PK parameters BUT different sampling times. Tabulate your AUCs and compare the results for different sampling times!

It is of course possible to calculate the AUC without any influence of the sampling frequency. You should be able to find examples of how to do this in the NMusers archive. See for example the answer from Mats Karlsson in this thread ( http://nonmem.org/nonmem/nm/98apr032002.html).
