Bioavailability is 48% to 79%. Fasting increases absorption. Effective by parenteral route. Circulating thyroid hormones are greater than 99% bound to plasma proteins, including thyroxine-binding globulin TBG thyroxine-binding prealbumin TBPA and albumin TBA whose capacities and affinities vary for each hormone. The higher affinity of both TBG and TBPA for T 4 partially explains the higher serum levels, slower metabolic clearance, and longer half-life of T 4 compared to T 3. Protein-bound thyroid hormones exist in reverse equilibrium with small amounts of free hormone. Only unbound hormone is metabolically active. azulfidine
