Liothyronine is a synthetic form of thyroid hormone (T 3) used to treat hypothyroidism and myxedema coma. It is also used as an augmentation strategy in treating Major Depressive Disorder when used in combination with antidepressants. Liothyronine may cause a number of side effects, mostly similar to symptoms of hyperthyroidism, which include: 1  weight loss. 2  tremor. 3  headache. 4  upset stomach. 5  vomiting. 6  diarrhea. 7  stomach cramps. 8  nervousness. 9  irritability. 10  insomnia. 11  excessive sweating. 12  increased appetite. 13  fever. 14  changes in menstrual cycle. 15  sensitivity to heat. Thyroid hormone drugs are natural or synthetic preparations containing tetraiodothyronine (T 4, levothyroxine) sodium or triiodothyronine (T 3, liothyronine) sodium or both. T 4 and T 3 are produced in the human thyroid gland by the iodination and coupling of the amino acid tyrosine. Cytomel (liothyronine sodium) Tablets may be used in preference to levothyroxine (T 4) during radioisotope scanning procedures, since induction of hypothyroidism in those cases is more abrupt and can be of shorter duration. It may also be preferred when impairment of peripheral conversion of T 4 to T 3 is suspected. Cytomel (liothyronine sodium) Tablets may be used in preference to levothyroxine (T 4) during radioisotope scanning procedures, since induction of hypothyroidism in those cases is more abrupt and can be of shorter duration. It may also be preferred when impairment of peripheral conversion of T 4 to T 3 is suspected. Recommended starting dosage is 5 mcg daily, with a 5 mcg increment every 3 to 4 days until the desired response is achieved. Infants a few months old may require only 20 mcg daily for maintenance. At 1 year, 50 mcg daily may be required. Above 3 years, full adult dosage may be necessary (see Precautions; Pediatric Use). Iodine content is only an indirect indicator of true hormonal biologic activity. Cytomel (liothyronine sodium) (liothyronine sodium) Tablets contain liothyronine (L-triiodothyronine or LT3), a synthetic form of a natural thyroid hormone, and is available as the sodium salt. The structural and empirical formulas and molecular weight of liothyronine sodium are given below. Liothyronine Sodium. 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 BRAND NAME: Cytomel, Triostat. DRUG CLASS AND MECHANISM: Liothyronine sodium is a synthetic (man-made) version of one of the two hormones made by the thyroid gland, triiodothyronine. It is used for treating individuals who are hypothyroid (do not produce enough thyroid hormones). In adults, thyroid hormones help to maintain the function of the brain, the use of food by the body, and body temperature. The FDA approved liothyronine in May 1956. PRESCRIBED FOR: Liothyronine is used to treat hypothyroidism (low production of thyroid hormone) in adults and children. Cytomel (liothyronine sodium) Tablets contain liothyronine (L-triiodothyronine or LT 3), a synthetic form of a natural thyroid hormone, and is available as the sodium salt. The structural and empirical formulas and molecular weight of liothyronine sodium are given below. Cytomel (liothyronine sodium) Tablets may be used in preference to levothyroxine (T 4) during radioisotope scanning procedures, since induction of hypothyroidism in those cases is more abrupt and can be of shorter duration. It may also be preferred when impairment of peripheral conversion of T 4 to T 3 is suspected. Physicians can use this instead of or in addition to levothyroxine (T 4) for patients undergoing thyroid withdrawal. When a patient has thyroid cancer or Graves' disease, ablation therapy with radioactive iodine (131I) can be used to remove any trace thyroid tissue. Liothyronine may cause a number of side effects, mostly similar to symptoms of hyperthyroidism, which include: 1  weight loss. 2  tremor. 3  headache. 4  upset stomach. 5  vomiting. 6  diarrhea. 7  stomach cramps. 8  nervousness. 9  irritability. 10  insomnia. 11  excessive sweating. 12  increased appetite. 13  fever. 14  changes in menstrual cycle. 15  sensitivity to heat.

Levothyroxine (INN, USAN) or L-thyroxine is a synthetic thyroid hormone that is chemically identical to thyroxine (T 4), which is naturally secreted by the follicular cells of the thyroid gland. It is used to treat thyroid hormone deficiency, and occasionally to prevent the recurrence of thyroid cancer. Like its naturally secreted counterpart, levothyroxine is a chiral compound in the L-form. The related drug dextrothyroxine ( Liothyronine is given when the thyroid does not produce enough of this hormone on its own. Liothyronine treats hypothyroidism (low thyroid hormone). Liothyronine is also used to treat or prevent goiter (enlarged thyroid gland), and is also given as part of a medical tests for thyroid disorders. Liothyronine should not be used to treat obesity or weight problems. Liothyronine may also be used for purposes not listed in this medication guide.
