Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The pharmacokinetic study relates to a single HDF session, where the antibiotic (meropenem or tazocin) will be administered intravenously at 30 minutes prior to the start of the dialysis session. Basline bloods are taken. The anitbiotic is administered followed by a 15 and 30 minute sample. The dialysis session is then started and samples are then taken (15 min, 30 min, 60 min, 2 hours and 4 hours) to measure antibiotic concentrations over time during the 4 hour dialysis session followed by a post dialysis sample 1 hour after completion..
Dose of Meropenem is 1gm IV (session 1)
Dose of tazocin 4.5gms IV (session 2).
Each participant will undergo 2 pharmacokinetic clearance studies on HDF. One for meropenem pharmacokinetics and one for Tazocin pharmacokinetics These studies will be separated by at least a week.

Outcomes
Primary outcome [1] 297098 0
Determination of pharmacokinetics of meropenem or tazocin for stable haemodialysis patients during a single session of haemodiafiltration.
The pharmacokinetics of these drugs during a HDF session will be estimated using a population pharmacokinetic approach with the standard software NONMEM (ver 7.2.0).
Cmax, Tmax, AUC and clearances will all be measured.
Timepoint [1] 297098 0
Timed sampling across a dialysis session.
Baseline pre-antibiotic dose, then at 15min,prior to commencement of HDF.
Following commencement of HDF, blood samples will be collected at 15 min, 30 min, 45 min, 60 min, 2hours, and 4hours (completion of HDF session and a final sample 1 hour post HDF.
Blood samples wil be taken before and after dialysis membrane.
Dialysate samples: baseline, 30 mins, 60 mins, 2 hours, 4 hours.

Intervention assignment
Other design features
Phase
Type of endpoint/s
Statistical methods / analysis
There is no data on the pharmacokinetics of meropenem or tazocin for patients on haemodiafiltration, so a power calculation is not appropriate. with the multiple blood sampling.
6 participants will provide sufficient pharmacokinetic data to undertake modeling.using a population pharmacokinetic approach with the standard software NONMEM (ver 7.2.0).
