Neo-Mercazole is an antithyroid agent. Once converted to its active form of methimazole, it prevents the thyroid peroxidase enzyme from coupling and iodinating the tyrosine residues on thyroglobulin, hence reducing the … The introduction of an ethoxycarbonyl group in methimazole and its selenium analogue not only prevents the oxidation to the corresponding disulfide and diselenide but also reduces the zwitterionic character. Pharmacology: Pharmacodynamics: Carbimazole (Neomerdin) is a pro-drug which undergoes rapid and virtually complete metabolism to the active metabolite, Thiamazole also known as Methimazole.

It works by reducing the amount of thyroid hormones made in your thyroid gland; It can be used on its own, or with other treatments for an over-active thyroid gland; It can also be used before part of the thyroid gland has been removed by surgery.

Neo-Mercazole is an antithyroid agent. Methimazole prevents thyroid peroxidase enzyme from iodinating and coupling the tyrosine residues on thyroglobulin, hence reducing the production of the thyroid hormones T3 and T4 (thyroxine). SUMMARY Carbimazole (CBZ) is one of the major drugs currently used for the treatment of Graves' disease. For more information, visit PharmAcademy: sites.google.com/exeter.ac.uk/pharmacademy/home The method of action is believed to be inhibition of the organification of iodide and the coupling of iodothyronine residues which in turn suppress the synthesis of thyroid hormones.
