51-48-9 Anti Estrogen Steroids L-Thyroxine Medication Levothyroxine 51-48-9 Epinephrine Hydrochloride

White Powder Anesthetic Anodyne L-Thyroxine 51-48-9 Epinephrine Hydrochloride

Description:

Levothyroxine, also known as L-thyroxine, is a synthetic thyroid hormone that is chemically identical to

thyroxine (T₄), 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 drugdextrothyroxine

(D-thyroxine) was used in the past as a treatment for hypercholesterolemia (elevated cholesterol levels)

but was withdrawn due to cardiac side effects.

Usage:

One of the thyroid hormones involved in the maintenance of metabolic homeostasis. Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid. Synthesis and secretion are regulated by the people.

Applications

levothyroxine is typically used to treat hypothyroidism, and is the treatment of choice for patients 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 (tsh), a hormone that is considered goiter-inducing. levothyroxine is also used as interventional therapy in patients with nodular thyroid disease or thyroid cancer to suppress thyroid-stimulating hormone (tsh) secretion. in 1992, president george h. w. bush told television host larry king that he had been prescribed levothyroxine as part of a treatment regimen for graves' disease.
side effects: this medication should not be used for weight loss. normal doses of this medication will not work for weight loss, and large doses of this medication may cause serious, possibly fatal side effects, especially when taken with diet pills.

Side effects

Adverse events are generally caused by incorrect dosing. Long-term suppression of TSH values below normal values will frequently cause cardiac side-effects and contribute to decreases in bone mineral density (low TSH levels are also well known to contribute to osteoporosis).

Too high a dose of levothyroxine generates effects that mimic hyperthyroidism. Overdose can result in heart palpitations, abdominal pain, nausea, anxiousness, confusion, agitation, insomnia, weight loss, and increased appetite. Allergic reactions to the drug are characterized by symptoms such as difficulty breathing, shortness of breath, or swelling of the face and tongue. Acute overdose may cause fever, hypoglycemia, heart failure,coma, and unrecognized adrenal insufficiency.

Acute massive overdose may be life-threatening; treatment should be symptomatic and supportive. Massive overdose can be associated with increasedsympathetic activity and thus require treatment with beta-blockers.
