QUICK LOOK AT THE CHAPTER AHEAD
Thyroid agents are used to treat hypothyroidism. Hypothyroidism is called myxedema in adults and cretinism in children. Goiter may also occur in some forms of hypothyroidism and results in an enlarged thyroid gland. Synthetic thyroid agents are usually more prescribed as they are more stable and standardized than desiccated or natural thyroid.1
Treatment of hypothyroidism is aimed at eliminating symptoms so that normal hormonal balance is restored.
