About:

Neomercazole is an anti-thyroid substance which depresses the formation of thyroid hormone. It reduces the uptake and concentration of inorganic iodine by the thyroid but its main effect is to reduce the formation of di-iodotyrosine and thyroxine.

It is absorbed rapidly from the gastro-intestinal tract and is widely distributed throughout the body. Neomercazole is completely metabolised to methimazole and it is the metabolite that is responsible for its clinical activity.

Neomercazole readily crosses the placental barrier and also attains a high concentration in the milk of lactating patients. Excretion in the urine is rapid. The elimination half-life of methimazole may be increased in hepatic and renal impairment.
