Carbimazole--resistant thyrotoxicosis.

Treatment of thyrotoxicosis resistant to carbimazole with corticosteroids.

We report two patients whose thyrotoxicosis failed to respond to conventional treatment with carbimazole. The patients remained persistently hyperthyroid, both clinically and biochemically, despite several months of carbimazole therapy at the maximum recommended doses. Prednisolone 20 mg per day was then given in addition to the antithyroid drug and a dramatic response observed in both cases. T...

Carbimazole (Neo-Mercazole) in Thyrotoxicosis

stressed the freedom from toxicity and potency of carbimazole as an anti-thyroid drug. Though potent, thiourea derivatives had proved to have a significant toxic risk. For this reason, most recent workers have concentrated on a comparison of carbimazole with thiourea drugs in regard to studies of toxicity. McGavack, et al. (1956), in describing their experiences in forty-one cases with special ...

Thyrotoxicosis: relations between clinical state and biochemical changes during carbimazole treatment.

The relation between clinical and biochemical changes in thyrotoxicosis were studied in 12 patients with Graves's disease who were being treated with carbimazole. Clinical assessment (using the Crooks-Wayne index) was combined with the measurement of free thyroxine and triiodothyronine indices (FT4I and FT3I) and the assessment of two tissue markers of thyroid hormone action--sex-hormone-bindin...

Comparison of the efficacy of single and multiple regimens of carbimazole in the treatment of thyrotoxicosis.

Carbimazole, in 3 divided daily doses, is commonly prescribed for the treatment of thyrotoxicosis. However, based on its long intra-thyroid half-life, the drug may be effective when used as a single or twice daily dose. This study was undertaken to determine the effect of once, twice or thrice daily doses of carbimazole on thyroid function in patients with thyrotoxicosis. Seventy previously unt...
