LIOTHYRONINE SODIUM TABLETS, USP
Drugs with thyroid hormone activity, alone or together with other
therapeutic agents, have been
used for the treatment of obesity. In euthyroid patients, doses within
the range of daily hormonal
requirements are ineffective for weight reduction. Larger doses may
produce serious or even
life-threatening manifestations of toxicity, particularly when given
in association with
sympathomimetic amines such as those used for their anorectic effects.
DESCRIPTION
Thyroid hormone drugs are natural or synthetic preparations containing
tetraiodothyronine (T
,
levothyroxine) sodium or triiodothyronine (T
, liothyronine) sodium or both. T
and T
are produced
in the human thyroid gland by the iodination and coupling of the amino
acid tyrosine. T
contains four
iodine atoms and is formed by the coupling of two molecules of
diiodotyrosine (DIT). T
contains
three atoms of iodine and is formed by the coupling of one molecule of
DIT with one molecule of
monoiodotyrosine (MIT). Both hormones are stored in the thyroid
colloid as thyroglobulin.
Thyroid hormone preparations belong to two categories: (1) natural
hormonal preparations derived from
animal thyroid, and (2) synthetic preparations. Natural preparations
include desiccated thyroid and
thyroglobulin. Desiccated thyroid is derived from domesticated animals
that are used for food by man
(either beef or hog thyroid), and thyroglobulin is derived from
thyroid glands of the hog. The United
States Pharmacopeia (USP) has standardized the total iodine content of
natural preparations. Thyroid
USP contains not less than (NLT) 0.17 percent and not more than (NMT)
0.23 percent iodine, and
thyroglobulin contains not less than (NLT) 0.7 percent of organically
bound iodine. Iodine content is
only an indirect indicator of true hormonal biologic activity.
Liothyronine Sodium Tablets, USP contain liothyronine
(L-triiodothyronine or LT
), a synthetic form
of a natural thyroid horm
