Which medication is commonly used for treating hyperthyroidism?

Methimazole is commonly used for treating hyperthyroidism because it functions as an antithyroid medication, inhibiting the synthesis of thyroid hormones. By blocking the action of an enzyme called thyroid peroxidase, methimazole reduces the production of hormones thyroxine (T4) and triiodothyronine (T3), which are often produced in excess in hyperthyroid conditions.

This medication is specifically favored for managing conditions like Graves' disease and toxic nodular goiter, as it effectively helps to lower hormone levels and mitigate symptoms of hyperthyroidism such as weight loss, rapid heartbeat, and anxiety. It is crucial for the management of this condition because it targets the underlying issue rather than simply alleviating symptoms.

Levothyroxine is used to treat hypothyroidism and is the synthetic form of the thyroid hormone, working opposite to what is required for hyperthyroidism. Carbimazole is another antithyroid medication similar to methimazole, but it is not as commonly used in some regions. Propranolol, while it can be used to address symptoms of hyperthyroidism (such as rapid heart rate), does not treat the actual hormonal imbalance. Thus, methimazole is the most appropriate choice for
