Propylthiouracil is also used for an overactive thyroid gland in pregnancy. MECHANISM OF ACTION OF THYROID HORMONES Act mainly by the binding of T 3 to a specific nuclear receptor T 4 is not biologically active in normal physiology When T 3 is bound, the gene transcription is activated, resulting in generation of mRNA and protein synthesis.
