TTR stabilizers are used to treat cardiomyopathy, or problems with the heart muscle, related to transthyretin-mediated amyloidosis. TTR stabilizers work by stabilizing the transthyretin protein, preventing it from breaking down and forming amyloid deposits in the heart. These medications are available in oral forms. Examples include tafamidis (Vyndamax, Vyndaqel). You can take these medications as prescribed to help manage your condition effectively.
