What is levothyroxine? Levothyroxine, marketed under the brand name Synthroid and others, is a medication that contains levothyroxine (T4) sodium. Synthetic T4 in levothyroxine is based on T4 produced by the thyroid gland. Oral levothyroxine sodium has the same physiological effect as endogenous T4 and helps maintain normal T4 levels in the setting of a T4 deficiency. As much as 80% of the T4 ingested orally is absorbed by the GI tract. Most T4 is bound by plasma proteins and, is this state, is not considered metabolically active. Much of the T4 in the body is broken down by the liver. T4 is eliminated through the urine and the stool. The adequacy of therapy with levothyroxine should be assessed through periodic monitoring of T4 and TSH test levels in addition to clinical status. Levothyroxine and a similar medication, liothyronine, differ in that levothyroxine is T4 while its counterpart is T3 thyroid hormone. Both hormones are found in Armour Thyroid medication.
