Twenty-four hour hormone profiles of TSH, Free T3 and free T4 in hypothyroid patients on combined T3/T4 therapy

This study examined the 24-hour hormone profiles of TSH, free T3, and free T4 in 20 hypothyroid patients, comparing those on combined T3/T4 therapy (n=10) with those on T4 monotherapy (n=10). Patients on combined therapy experienced a 42% increase in fT3 levels within 4 hours post-dose, while those on T4

Single-dose T3 administration: kinetics and effects on biochemical and physiological parameters

This study examined the effects of a single 50-mcg dose of liothyronine (T3) on thyroid hormones, thyroid-stimulating hormone (TSH), and vital signs over four days in 12 healthy euthyroid participants. Triiodothyronine levels peaked at 2.5 hours post-administration, while heart rate significantly increased within 5 hours (p=0.009). TSH suppression was observed
