Liothyronine is the most potent form of thyroid hormone. Chemically, it is nearly identical to triiodothyronine (T3). そのような, it acts on the body to increase the basal metabolic rate, affect protein synthesis and increase the body's sensitivity to catecholamines (such as adrenaline) by permissiveness. The thyroid hormones are essential to proper development and differentiation of all cells of the human body. These hormones also regulate protein, fat, and carbohydrate metabolism, affecting how human cells use energetic compounds.
T3 is a regulator of the oxidative metabolism of energy. When you take liothyronine sodium it will increase the uptake of nutrients into the mitochondria, which raises activity in the oxidative metabolic pathway. This causes everything to work harder within the organism and makes the body demand more fuel.
Liothyronine is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally made by the thyroid gland. Liothyronine is a man-made form of thyroid hormone.
Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone helps you stay healthy. For children, having enough thyroid hormone helps them grow and learn normally.
This medication is also used to treat other types of thyroid problems (such as certain types of goiters, thyroid cancer).
It can also be used to test for certain types of thyroid disease.This medication should not be used to treat infertility unless it is caused by low thyroid hormone levels.
