Heart Disease. Heart, or cardiovascular, disease is responsible for nearly half of all deaths in the United States each year, killing nearly one million people each year, and afflicting over 60 million others.
In adults, thyroid hormones help to maintain the function of the brain, the use of food by the body, and body temperature. The FDA approved liothyronine in May 1956. PRESCRIBED FOR: Liothyronine is used to treat hypothyroidism (low production of thyroid hormone) in adults and children. Prolonged hypothyroidism can result in a condition called myxedema in which patients develop swollen lips, thickened nose, and unusual deposits of material in the skin that are dry and waxy.
Levothyroxine is typically used to treat hypothyroidism, and is the treatment of choice for people with hypothyroidism, who often require lifelong thyroid hormone therapy. It may also be used to treat goiter via its ability to lower thyroid-stimulating hormone (TSH), a hormone that is considered goiter-inducing.
