Description;

 

Levothyroxine or L-thyroxine is a synthetic thyroid hormone that is chemically identical to thyroxine , which is naturally secreted by the follicular cells of the thyroid gland. It is used to treat thyroid hormone deficiency, and occasionally to prevent the recurrence of thyroid cancer. Like its naturally secreted counterpart, levothyroxine is a chiral compound in the L-form. The related drug dextrothyroxine was used in the past as a treatment for hypercholesterolemia but was withdrawn due to cardiac side effects

 

Levothyroxine is typically used to treat hypothyroidism and is the treatment of choice for people with hypothyroidism,who often require lifelong thyroid hormone therapy.It may also be used to treat goiter via its ability to lower thyroid-stimulating hormone, a hormone that is considered goiter-inducing.Levothyroxine is also used as interventional therapy in people with nodular thyroid disease or thyroid cancer to suppress thyroid-stimulating hormone secretion.A subset of people with hypothyroidism treated with an appropriate dose of levothyroxine will describe continuing symptoms despite TSH levels in the normal range.[6] In these people, further laboratory and clinical evaluation is warranted as they may have another cause for their symptoms.Furthermore, it is important to review their medications and possible dietary supplements as several medications can affect thyroid hormone levels.

 

Applications;

 

L-thyroxine as medication is identical to the L-thyroxine which is the major hormone made by the thyroid gland,L-thyroxine is the most commonly prescribed form of thyroid hormone replacement,Stable blood levels of thyroid hormone are achieved when L-thyroxine is taken at approximately the same time each day, ideally the first thing in the morning on an empty stomach.
Use of thyroid hormones to treat vague symptoms such as dry skin, fatigue, constipation, abnormalities of reproductive function, growth retardation, or obesity without laboratory confirmation of contributing hypothyroidism is inappropriate and may cause hyperthyroidism in euthyroid individuals.
