They inhibit release of thyroid hormones by the thyroid gland.The most studied drug in this class is lithium, which inhibits thyroid hormone secretion by inhibiting iodotyrosine coupling, thyroidal iodide uptake, and alteration in structure of thyroglobulin, [10] a protein which acts as a substrate for the synthesis of thyroid hormones and storage of inactive forms of T3, T4 and iodine within ...
ATC code H03 Thyroid therapy is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products.
Analogues of peptides can also be used as drugs with an improved oral bioavailability. Thioamides inhibit the enzyme thyroid peroxidase in the thyroid, reducing the synthesis of triiodothyronine (T 3) and thyroxine (T 4), thereby blocking uptake of iodotyrosines from the colloid. They also block iodine release from peripheral hormone.
Thyroid diseases are highly prevalent worldwide, [10] [11] [12] and treatment varies based on the disorder. Levothyroxine is the mainstay of treatment for people with hypothyroidism, [13] while people with hyperthyroidism caused by Graves' disease can be managed with iodine therapy, antithyroid medication, or surgical removal of the thyroid ...
Antithyroid autoantibodies (or simply antithyroid antibodies) are autoantibodies targeted against one or more components on the thyroid. The most clinically relevant anti-thyroid autoantibodies are anti- thyroid peroxidase antibodies (anti-TPO antibodies, TPOAb), thyrotropin receptor antibodies (TRAb) and thyroglobulin antibodies (TgAb).
Thiamazole is a drug used to treat hyperthyroidism such as in Graves' disease, a condition that occurs when the thyroid gland begins to produce an excess of thyroid hormone. The drug may also be taken before thyroid surgery to lower thyroid hormone levels and minimize the effects of thyroid manipulation.
Propylthiouracil is in the antithyroid family of medications. [4] It works by decreasing the amount of thyroid hormone produced by the thyroid gland and blocking the conversion of thyroxine (T4) to triiodothyronine (T3). [3] Propylthiouracil came into medical use in the 1940s. [5] It is on the World Health Organization's List of Essential ...
Carbimazole is a pro-drug as after absorption it is converted to the active form, methimazole. Methimazole prevents thyroid peroxidase enzyme from iodinating and coupling the tyrosine residues on thyroglobulin, hence reducing the production of the thyroid hormones T 3 and T 4 . It is on the World Health Organization's List of Essential Medicines.
