Total Dialysate Clearance for Automated Peritoneal Dialysis (CLDAPD) of Oseltamivir and Oseltamivir Carboxylate for 75 mg Dose
Query!
Assessment method [1]
0
0
CLDAPD is the total dialysate clearance for automated peritoneal dialysis, attributable to both continuous cycler-assisted peritoneal dialysis (CCPD) and continuous ambulatory peritoneal dialysis (CAPD), which was calculated with the recovery method over the dense blood sampling collection interval from 0 to 48 hours post-dose.
CLDAPD = the amount excreted into dialysate from 0 to 48 hours (Aed\[0-48\])/ plasma area under the concentration-time curve from time zero through 48 hours (AUC\[0-48\])
CLDCCPD = mean of CLDCCPD from the 2 CCPD sessions, calculated as CLDCCPD = (Aed\[0-8\]/AUC\[0-8\] + Aed\[24-32\]/AUC\[24-32\]) / 2
CLDCAPD = mean of CLDCAPD from the 3 CAPD sessions, calculated as CLDCAPD = (Aed\[8-16\]/AUC\[8-16\] + Aed\[16-24\]/AUC\[16-24\] + Aed\[32-48\]/AUC\[32-48\]) / 3

Laboratory analysis included: hematology (hemoglobin, hematocrit, reticulocyte, red blood cell, platelet and white blood cell count, mean corpuscular volume, mean corpuscular hemoglobin), prothrombin and activated partial thromboplastin time, biochemistry (sodium, potassium, bicarbonate, phosphate, chloride, calcium, urea, serum creatinine, bilirubin, cholesterol, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase \[ALT\], gamma-glutamyl transferase, protein, albumin, amylase, creatinine, lipase), random glucose, and urinalysis.
Laboratory test result values falling outside of the marked abnormality range that also represent a defined change from baseline were considered as marked laboratory abnormalities. A marked reference range for sodium is 130-150 millimole (mmol)/L, chloride is 95-115 mmol/L, phosphate is 0.75-1.60 mmol/L, calcium is 2-2.90 mmol/L, glucose is 2.8-11.10 mmol/L, bicarbonate is 18-28 mmol/L, and ALT is 0-110 Unit/L.
