Quantifying Amount of Adsorption of Levothyroxine by Percutaneous Endoscopic Gastrostomy Tubes

Abstract

Although the authors found statistically significant differences in mean drug concentrations, they conclude that the amount of uptake of levothyroxine by PEG tubes and adsorption of levothyroxine by PEG tubes is probably clinically insignificant. The differences found may be attributed to the amount of drug lost during crushing and transfer.
