Levothyroxine (also marketed as Levoxyl, Levothroid, Synthroid, or L-thyroxine sodium) is the only thyroid system prescription that has recently featured prominently among the top 200 medications in the United States. Thus, 75.1 million, 80.7 million, and 79.4 million levothyroxine prescriptions were dispensed in 2003, 2004, and 2005, respectively.

Thyroxine sodium, Ci5Hio04Nl4Na,5H20, Mol. Wt. 889-0, is the sodium salt of L-thyroxine. It may be assayed by the oxygen-flask combustion method as described in Appendix IV using about 13 mg and titrating with 0-02N sodium thiosulphate. 1 ml 0-02N = 0-0006657 g anhydrous. [Pg.641]

Tablets of Thyroxine Sodium, B.P. Usually contain 0-05 mg. These tablets contain too much organic matter for application of the flask-combustion method. Tablets of Thyroxine Sodium, B.P. Usually contain 0-05 mg. These tablets contain too much organic matter for application of the flask-combustion method.
Weigh an amount of powdered tablets equivalent to about 1-5 mg of thyroxine sodium into a nickel crucible about 6 mm in diameter and about 6 mm deep and add 3 ml of water followed by 5 g of sodium hydroxide in small pieces. Heat on a water-bath to remove the water, add a further 4 g of sodium hydroxide and heat over a Bunsen flame, at first gently and then sufficiently strongly to maintain the mixture in a... [Pg.641]
