How effective are Levothyroxine Na tablets 50 mcg from Japan for thyroid hormone therapy?
Levothyroxine Na tablets contains levothyroxine sodium hydrate. It is a sodium salt of levothyroxine, the synthetic isomer of thyroxine which is similar to the endogenous hormone produced by the thyroid gland. Levothyroxine Na tablets are effective for the treatment of hypothyroidism and its consequences, such as myxedema or myxedema coma. They work by binding to thyroid receptor proteins in the cell nucleus, controlling DNA transcription and protein synthesis and subsequently causing metabolic effects.
Who should use Levothyroxine Na tablets 50 mcg from Japan?
Levothyroxine Na tablets are used both for relieving acute symptoms, such as skin swelling or seizures, and for long-term hormone replacement therapy. As the tablets have an ability to lower goiter-inducing thyroid-stimulating hormone, they are also used for treating goiter. Levothyroxine is prescribed as interventional therapy in patients with nodular thyroid disease or thyroid cancer for suppressing thyroid-stimulating hormone secretion (S. J. Mandel, G. A. Brent, P. R. Larsen. Levothyroxine therapy in patients with thyroid disease. Annals of Internal Medicine. 1993, September, 119(6): 492–502).
