cat

Plain-English summary

A group of 40 cats with hyperthyroidism (a condition where the thyroid gland is overactive) were treated with a radioactive iodine capsule. After receiving doses of 200 to 300 mBq, 36 of the cats, or 90%, showed improvement, with their symptoms resolving and thyroid hormone levels returning to normal. This method is less stressful for the cats compared to other treatments and provides a convenient option for managing this condition. Most cats responded well to the treatment and were healthier afterward.

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.
