Brand: Thyreostat II
Category: Antithyroid Agents, Antimetabolites
CAS number: 51-52-5
Pharmacology
Indication: Used to manage hyperthyroidism which is due to an overactive thyroid gland (Grave's disease).
Pharmacology:
Propylthiouracil is a thiourea antithyroid agent. Grave's disease is the most common cause of hyperthyroidism. It is an autoimmune disease where an individual's own antibodies attach to thyroid stimulating hormone receptors within cells of the thyroid gland and then trigger overproduction of thyroid hormone. The two thyroid hormones manufactured by...

Mechanism of Action:
Propylthiouracil binds to thyroid peroxidase and thereby inhibits the conversion of iodide to iodine. Thyroid peroxidase normally converts iodide to iodine (via hydrogen peroxide as a cofactor) and also catalyzes the incorporation of the resulting iodide molecule onto both the 3 and/or 5 positions of the phenol rings of tyrosines found in thyroglob...
