This dose is taken until the hormone levels in your blood have stabilised, usually about four to eight weeks later. Medical therapy for hyperthyroidism typically involves either titrating the dose of Carbimazole until the patient becomes euthyroid or maintaining a high dose of Carbimazole to suppress endogenous thyroid production, and then replacing thyroid hormone with levothyroxine ("block and replace"). A model incubation system containing purified thyroid peroxidase (TPO) was used to study the mechanism of action of the thioureylene antithyroid drugs—propylthiouracil (PTU), methylmercapto imidazole (MMI) and carbimazole.

Neo-Mercazole is believed to exert its antithyroid effect by ‘blocking’ the organic binding of iodine through inhibition of the iodination of tyrosine. A severity rating for each drug interaction, from minor to major. Blocks synthesis of thyroxine and triiodothyronine (T3); does not inactivate circulating T4 and T3. 1979 Jun;10(6):637-48. Carbimazole has a higher molecular weight than methimazole, so 5 mg of carbimazole is equivalent to 3 mg of methimazole. It is also used to prepare patients for thyroidectomy. Together with the reported differential in remission rates between propranolol and anti-thyroid drugs, it is concluded that carbimazole does not act solely by inhibiting intrathyroid hormono-genesis, but more definitively by affecting thyroid hyperstimulation at a pre-biosynthetic level. 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. It is used to treat hyperthyroidism and thyrotoxicosis. Carbimazole should be used judiciously in pregnancy as it crosses the placenta.
