Indication: It is suitable for long-term replacement therapy of congenital hypothyroidism (cretinism) and hypothyroidism caused by various reasons in children and adults. It can also be used for simple goiter, chronic lymphocytic thyroiditis, and suppression (and replacement) therapy after thyroid cancer surgery. It can sometimes be used as an adjuvant therapy for hyperthyroidism and can also be used for thyroid suppression tests.

Indication: 1. Diagnosis and differential diagnosis of coronary artery disease (myocardial ischemia, myocardial infarction), and guiding treatment, which helps to understand the effect of thrombolytic therapy; using gate circuit controlled imaging software, it can simultaneously measure the whole heart and local ejection fraction, evaluate local ventricular wall motion, and have a more comprehensive understanding of cardiac function; 2. Localization diagnosis of parathyroid hyperplasia adenoma; Localization of thyroid cancer (such as medullary carcinoma, lymphoma, Hurthle cell carcinoma).

Indication: INDICATIONS AND USAGE
ADTHYZAtrademark (thyroid tablets, USP) are indicated: As replacement or supplemental therapy in patients with hypothyroidism of any etiology, except transient hypothyroidism during the recovery phase of subacute thyroiditis. This category includes cretinism, myxedema, and ordinary hypothyroidism in patients of any age (children, adults, the elderly), or state (including pregnancy); primary hypothyroidism resulting from functional deficiency, primary atrophy, partial or total absence of thyroid gland, or the effects of surgery, radiation, or drugs, with or without the presence of goiter; and secondary (pituitary), or tertiary (hypothalamic) hypothyroidism (See WARNINGS As pituitary TSH suppressants, in the treatment or prevention of various types of euthyroid goiters, including thyroid nodules, subacute or chronic lymphocytic thyroiditis (Hashimoto''s), multinodular goiter, and in the management of thyroid cancer.
Hypothyroidism
Therapy is usually instituted using low doses, with increments which depend on the cardiovascular status of the patient. The usual starting dose is 32.5 mg ADTHYZAtrademark (thyroid tablets, USP), with increments of 16.25 mg every 2 to 3 weeks. A lower starting dosage, 16.25 mg/day, is recommended in patients with long-standing myxedema, particularly if cardiovascular impairment is suspected, in which case extreme caution is recommended. The appearance of angina is an indication for a reduction in dosage. Most patients require 65 to 130 mg/day. Failure to respond to doses of 195 mg suggests lack of compliance or malabsorption. Maintenance dosages 65 to 130 mg/day usually result in normal serum T4 and T3 levels. Adequate therapy usually results in normal TSH and T4 levels after 2 to 3 weeks of therapy. Readjustment of thyroid hormone dosage should be made within the first four weeks of therapy, after proper clinical and laboratory evaluations, including serum levels of T4, bound and free, and TSH. Liothyronine (T3) may be used in preference to levothyroxine (T4) during radio-isotope 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 levothyroxine (T4) and liothyronine (T3) is suspected.
Thyroid Cancer
Exogenous thyroid hormone may produce regression of metastases from follicular and papillary carcinoma of the thyroid and is used as ancillary therapy of these conditions with radioactive iodine. TSH should be suppressed to low or undetectable levels. Therefore, larger amounts of thyroid hormone than those used for replacement therapy are required. Medullary carcinoma of the thyroid is usually unresponsive to this therapy.

Indication: Liothyronine sodium is an L-triiodothyronine (T3) indicated for: 1. 3 Limitations of Use - Not indicated for suppression of benign thyroid nodules and nontoxic diffuse goiter in iodine-sufficient patients. ( 1 - Not indicated for treatment of hypothyroidism during the recovery phase of subacute thyroiditis. ( 1 Liothyronine sodium is indicated as a replacement therapy in primary (thyroidal), secondary (pituitary), and tertiary (hypothalamic) congenital or acquired hypothyroidism. Liothyronine sodium is indicated as an adjunct to surgery and radioiodine therapy in the management of well-differentiated thyroid cancer. Liothyronine sodium is indicated as a diagnostic agent in suppression tests to differentiate suspected mild hyperthyroidism or thyroid gland autonomy. Limitations of Use Liothyronine sodium is not indicated for suppression of benign thyroid nodules and nontoxic diffuse goiter in iodine-sufficient patients as there are no clinical benefits and overtreatment with liothyronine sodium may induce hyperthyroidism [see Warnings and Precautions (5. Liothyronine sodium is not indicated for treatment of hypothyroidism during the recovery phase of subacute thyroiditis.
