Thyroid hormone receptor-beta agonists are used to treat conditions like metabolic dysfunction associated-steatohepatitis (MASH) with liver scarring. These medications work by activating thyroid hormone receptors in your liver, which helps to lessen the buildup of fatty substances in the liver. Thyroid hormone receptor-beta agonists are taken as oral pills. An example of this type of medication is Rezdiffra (resmetirom). You can take these medications as prescribed to help manage your condition effectively.
