Objective: The primary aim of the present investigation was to determine and compare the pharmacokinetic (PK) profiles of inorganic phosphate in serum and urine after intravenous administration of sodium glycerophosphate and inorganic sodium phosphate. Additionally, study product safety profiles were evaluated.
Subjects And Methods: In total, 27 healthy, white volunteers (17 male/10 female) were enrolled in this double-blinded, randomized, 2-sequence, crossover study and were assigned to receive an organic test drug (sodium glycerophosphate) and an inorganic reference preparation (sodium phosphate) on 2 occasions.
Background/aims: The primary objective of this study was to determine and compare the pharmacokinetic (PK) profiles of inorganic phosphate in the serum after continuous administration of pure glycerophosphate and glycerophosphate contained in total parenteral nutrition (TPN) emulsions. This approach was selected to identify potential PK interactions between TPN components and glycerophosphate.
Methods: The serum PK profile of inorganic phosphate after continuous intravenous administration of a sodium glycerophosphate containing TPN emulsion was determined in 10 healthy, white (5 male/5 female) volunteers.
