THE DESCRIPTION

Thyroid hormone medicines are natural or synthetic preparations that contain tetrabiodothyronine sodium (T4, levothyroxine) or triiodothyronine sodium (T3, liothyronine) or both. T4 and T3 are produced in the human thyroid gland by iodination and binding of the amino acid tyrosine. T4 contains four iodine atoms and is formed by the combination of two molecules of diiodothyrosine (DIT). T3 contains three iodine atoms and is formed by combining a DIT molecule with a monoiodothyrosine (MIT) molecule. Both hormones are stored in the thyroid colloid as thyroglobulin.

Thyroid hormone preparations are divided into two categories: (1) natural hormonal preparations derived from the thyroid gland of animals and (2) synthetic preparations. Herbal remedies include dried thyroid and thyroglobulin. The dried thyroid gland comes from domestic animals used by humans for food (cow or pig thyroid), and thyroglobulin comes from the pig thyroid gland. The United States Pharmacopoeia (USP) has standardized the total iodine content of natural preparations. Thyroid gland USP contains at least (NLT) 0.17 percent and not more (NMT) 0.23 percent iodine and thyroglobulin contains at least (NLT) 0.7 percent organically bound iodine. The iodine content is only an indirect indicator of actual hormonal biological activity.

Cytomel (liothyronine sodium) tablets contain liothyronine (L-triiodothyronine or LT3), a synthetic form of the natural thyroid hormone, and are available as the sodium salt.

The structural and empirical formulas and molecular weights of liothyronine sodium are shown below.
