Classification Of Thyroid Inhibitors

Thyroid inhibitors are medications that slow down the function of the thyroid gland.
They are typically used to treat conditions such as hyperthyroidism, where the thyroid gland is overactive. Common thyroid inhibitors include propylthiouracil (PTU) and methimazole (Tapazole). These medications work by blocking the production of thyroid hormones, which helps to reduce symptoms of hyperthyroidism.
Side effects of thyroid inhibitors can include rash, nausea, and liver problems, so it’s important to talk to your doctor before taking them.
