Plain-English summary
In this study, 40 cats with hyperthyroidism, a condition where the thyroid gland is overactive, were treated with a special form of iodine given by mouth. The dose used was between 200 to 300 millicuries, with 250 being the most common. After treatment, 36 of the cats, or 90%, showed improvement, meaning their symptoms went away and their thyroid hormone levels returned to normal or lower. While it seems that higher doses are needed when the iodine is given orally compared to through an injection, the oral method is less stressful for the cats and makes the treatment easier to provide. Overall, the treatment was successful for most of the cats involved in the study.
Abstract
SUMMARYForty cats with hyperthyroidism were treated using 200 to 300 (typically 250) mBq of orally administered131I. Thirty‐six cases (90%) were successfully treated, as assessed by resolution of clinical signs and reduction In plasma thyroxine concentrations to normal or reduced values after treatment. Although higher doses of131I appear to be required when the radioisotope is administered orally rather than Intravenously, a less stressful administration procedure and greater availability of therapy capsules offer useful advantages for treating thyrotoxic cats.
