Levothyroxine
The synthetic form of thyroxine (T4), the thyroid hormone, used in hypothyroidism; thyroxine was isolated in 1914 by Edward Kendall. This family brings together the active ingredient, pharmacopoeial impurities, metabolites, labelled standards and other impurities.
Did you know?In the United States it has for years been among the most prescribed medicines of all, and its dose is adjusted in micrograms: even small differences matter.
