Carbon-14 164-167 serpin family F member 2 Homo sapiens 181-184 28155137-3 2017 METHODS: Infants admitted to the intensive care unit received a single oral [14C]AAP microdose while receiving intravenous therapeutic AAP every 6 h. [14C]AAP pharmacokinetic parameters were estimated. Carbon-14 77-80 serpin family F member 2 Homo sapiens 81-84 28155137-4 2017 [14C]AAP and metabolites were measured with accelerator mass spectrometry. Carbon-14 1-4 serpin family F member 2 Homo sapiens 5-8 28155137-7 2017 Plasma [14C]AAP apparent total clearance was 0.4 (0.1-2.6) L/h/kg, apparent volume of distribution was 1.7 (0.9-8.2) L/kg, and the half-life was 2.8 (1-7) h. With increasing age, plasma and urinary AAP-glu/AAP and AAP-glu/AAP-sul ratios significantly increased by four fold, while the AAP-sul/AAP ratio significantly decreased. Carbon-14 8-11 serpin family F member 2 Homo sapiens 12-15 28155137-7 2017 Plasma [14C]AAP apparent total clearance was 0.4 (0.1-2.6) L/h/kg, apparent volume of distribution was 1.7 (0.9-8.2) L/kg, and the half-life was 2.8 (1-7) h. With increasing age, plasma and urinary AAP-glu/AAP and AAP-glu/AAP-sul ratios significantly increased by four fold, while the AAP-sul/AAP ratio significantly decreased. Carbon-14 8-11 serpin family F member 2 Homo sapiens 198-201 28155137-7 2017 Plasma [14C]AAP apparent total clearance was 0.4 (0.1-2.6) L/h/kg, apparent volume of distribution was 1.7 (0.9-8.2) L/kg, and the half-life was 2.8 (1-7) h. With increasing age, plasma and urinary AAP-glu/AAP and AAP-glu/AAP-sul ratios significantly increased by four fold, while the AAP-sul/AAP ratio significantly decreased.

Carbon-14 8-11 serpin family F member 2 Homo sapiens 198-201 28155137-8 2017 CONCLUSION: Using [14C]labeled microdosing, the effect of age on orally administered AAP metabolism was successfully elucidated in both plasma and urine.
