Used primarily in the treatment of hyperthyroidism, this compound functions by inhibiting the synthesis of thyroid hormones. It interferes with the enzyme thyroid peroxidase, which is essential for the production of thyroxine (T4) and triiodothyronine (T3). This action helps reduce the excessive metabolic activity seen in patients with overactive thyroid glands. Due to its antithyroid properties, it has been employed in managing conditions such as Graves' disease. However, its use has declined in favor of other agents with more favorable safety profiles. It may also find limited use in veterinary medicine and in research settings for inducing hypothyroidism in experimental models.
