Urine Clearance of 11C-Metformin, 51Cr-EDTA, Protein Binding, and Metabolites in Plasma from 2 Pigs
| Parameter | Pig no. 5 | Pig no. 6 |
| ClMET (mL/min) | 348, 388 | 334 |
| ClEDTA (mL/min) | 114, 117 | 91 |
| ClMET/ClEDTA | 3.05, 3.32 | 3.67 |
| Protein binding (%) | <0.5 | <0.5 |
| Metabolites | None | None |
ClMET = urine clearance of 11C-metformin; ClEDTA = urine clearance of 51Cr-EDTA = glomerular filtration rate.
Pigs underwent constant infusion clearance technique experiments.
