Overview of Synthroid drug: when is it used and on what is it based
The medication you may know as Synthroid is a tableted medication Levothyroxine used in the insufficient function of thyroid gland. It is in fact sold under a variety of names with Synthroid being one of the most known in the U.S. and some other countries. It is permissible for other companies to make the same medicine because its formula was developed in the late twentieths of the 20th century. Therefore, it’s no longer protected by the exclusive patent. If you need to use Levothyroxine for your therapy, you can buy Generic Synthroid made by another company to save on the therapy as the less-known brands are sold at the lower prices.
The medications based on Levothyroxine are prescribed for the therapy of hypothyroidism of various genesis (including pregnancy), thyroid hormone deficiency, goitre recurrence (prophylaxis after resection), euthyroid benign goitre, additional thyrotoxicosis therapy with thyreostatic drugs following the achievement of the euthyroid status (not during pregnancy). It can be also used after the removal of thyroid due to cancer as a lifelong substitutive suppressive therapy. As a part of combination treatment, Synthroid and its analogs can be used for Graves' disease and autoimmune thyroiditis. Besides, the medication is used for thyroid function suppression test.
How does Synthroid act?
Synthroid or more precisely, the active agent of the medication promotes the replenishment of thyroid hormone deficiency. In little doses, it renders anabolic action, i.e. contributes to the growth of muscles. In average doses, the drug promotes growth and development and enhances the tissue need for oxygen. Besides, it regulates the metabolism of proteins, fats, and carbs, enhanced functional activity of the cardiovascular system and nervous system. In the large doses, it suppresses the production of thyrotropin-releasing and thyroid-stimulating hormones.
The effect of the medication in hypothyroidism occurs within three-five days of the therapy. Early diffuse hyperplastic goiter decreases or disappears within three to six months of the therapy. In the presence of nodes and late stages of the disease, a significant reduction in thyroid size is achieved in 30% of cases and virtually all patients are prevented from further growth of goiter.
Please, even if you believe that you may have been suffering from hypothyroidism, do not buy Synthroid if your doctor doesn’t appoint you the drug. It is a hormone-replacement medication which can be dangerous when used improperly or in the conditions it is contraindicated to be used.
