Continuous Methimazole Therapy and Its Effect on the Cure Rate of Hyperthyroidism Using Radioactive Iodine: An Evaluation by a Randomized Trial

Abstract

Continuous use of MTZ hinders an excessive increase of the thyroid hormones during (131)I therapy of hyperthyroid diseases. However, such a strategy seems to reduce the final cure rate, although this adverse effect paradoxically is attenuated by the concomitant reduction of the thyroid (131)I uptake.
