Metabolite Identification
Common NameCarbimazole
DescriptionCarbimazole is only found in individuals that have used or taken this drug. It is an imidazole antithyroid agent. Carbimazole is metabolized to methimazole, which is responsible for the antithyroid activity. [PubChem]Carbimazole is an aitithyroid agent that decreases the uptake and concentration of inorganic iodine by thyroid, it also reduces the formation of di-iodotyrosine and thyroxine. 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 production of the thyroid hormones T3 and T4.
