Thyrozol 5 mg film-coated tablets

Thyrozol is a brand of thiamazole (also known as methimazole), an antithyroid drug used in the treatment of hyperthyroidism. The brand has a long-standing history within the pharmaceutical industry, specifically associated with the German science and technology company Merck KGaA.

The product is primarily manufactured in Germany at Merck's central production facilities, though global distribution may involve local regional packaging centers depending on the market. As an established prescription medication, it fits into the broader portfolio of Merck's healthcare sector, which focuses on specialist pharmaceuticals and high-tech life science solutions.

Ownership of the Thyrozol brand remains with Merck KGaA, the world's oldest operating chemical and pharmaceutical company. It is important to distinguish this entity (Merck Group) from the American pharmaceutical giant Merck & Co. (MSD), as they have operated as separate companies since the end of World War I. Merck KGaA continues to lead the development and supply of this medication from its global headquarters in Darmstadt.
