Carbimazole and the Thioamide/Thioureylene family
The antithyroidal drugs <A HREF="http://www.hotsprings.freeserve.co.uk/#carbimazole">Carbimazole</A>, <A HREF="http://www.hotsprings.freeserve.co.uk/#carbimazole">Methimazole</A> and <A HREF="http://www.hotsprings.freeserve.co.uk/#propylthiouracil">Propylthiouracil</A> all
contain a thioamide group which is essential for antithyroid action.
Carbimazole, which is converted to Methimazole in the body is widely used in
the UK. <A HREF="http://www.hotsprings.freeserve.co.uk/#treatment">[Treatment]</A> Action
Decreases output of thyroid hormones from thyroid leading to a gradual
reduction in symptoms.
BMR and pulse rate return to normal over 3-4 weeks as stores of hormones must
be used up first.
Prevent hormone synthesis by blocking thyroid peroxidase catalysed reactions,
hence I2 and thyroglobulin do not complex and MIT and DIT are not formed.
They also block the coupling of iodotyrosines.
Propylthiouracil also reduces the de-iodination of T4 to T3. Methimazole does
this to a much lesser extent.
There is little evidence that the bulging
