The purpose of this study is to measure the area under the curve (AUC0-48h; extent of
systemic availability) and the maxi-mum concentrations (Cmax) of total serum levothyroxine
(TT4, bound and free fraction) after a single pharmacological dose of 600 μg administered as
tablets also containing iodine supple-ments vs. the same dose of levothyroxine administered
as a reference solution without iodine.
