Hyperthyroidism

Active Ingredient: Carbimazole

Indication for Carbimazole

Population group: only children (1 year - 12 years old) , adolescents (12 years - 18 years old) , adults (18 years old or older)
Therapeutic intent: Curative procedure

Carbimazole is an anti-thyroid agent. It is indicated in all conditions where reduction of thyroid function is required.

Such conditions are:

  • Hyperthyroidism.
  • Preparation for thyroidectomy in hyperthyroidism.
  • Therapy prior to and post radio-iodine treatment.

For this indication, competent medicine agencies globally authorize below treatments:

20-60 mg in 2-3 divided doses daily

For:

Route of admnistration

Oral

Defined daily dose

20 - 60 mg

Dosage regimen

From 6.667 To 20 mg 3 time(s) per day every day for 180 day(s)

Detailed description

The initial dose is in the range 20 mg to 60 mg, taken as two to three divided doses. The dose should be titrated against thyroid function until the patient is euthyroid in order to reduce the risk of over-treatment and resultant hypothyroidism.

Subsequent therapy may then be administered in one of two ways.

Maintenance regimen:

Final dosage is usually in the range 5 mg to 15 mg per day, which may be taken as a single daily dose. Therapy should be continued for at least six months and up to 18 months. Serial thyroid function monitoring is recommended, together with appropriate dosage modification in order to maintain a euthyroid state.

Blocking-replacement regimen:

Dosage is maintained at the initial level, i.e. 20 mg to 60 mg per day, and supplemental L-thyroxine, 50 mcg to 150 mcg per day, is administered concomitantly, in order to prevent hypothyroidism. Therapy should be continued for at least six months and up to 18 months. Where a single dosage of less than 20 mg is recommended, it is intended that carbimazole 5 mg should be taken.

15 mg daily

For:

Route of admnistration

Oral

Defined daily dose

15 - 15 mg

Dosage regimen

From 15 To 15 mg once every day

Detailed description

The usual initial daily dose is 15 mg per day adjusted according to response.

Safety and efficacy of carbimazole in children below 2 years of age have not been evaluated systematically. Use of carbimazole in children below 2 years of age is therefore not recommended.

Active ingredient

Carbimazole

Carbimazole, a thionamide, is a pro-drug which undergoes rapid and virtually complete metabolism to the active metabolite, thiamazole, also known as methimazole. 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.
