Levothyroxine is a synthetic homologue of the naturally occurring thyroid hormone, thyroxine (T4). It is converted to the more biologically active triiodothyronine (T3). Levothyroxine affects the metabolism of carbohydrates, proteins, fats, vitamins, nucleic acids and ions. Levothyroxine stimulates the consumption of oxygen and causes an increased metabolic activity by increasing the number of mitochondria. Protein synthesis is stimulated and the consumption of carbohydrates increases. The fat metabolism is stimulated.
