Levothyroxine Sodium: The Hormone for Hypothyroidism

Overview of Levotoid Levothyroxine Sodium Tablets:

Levothyroxine sodium is the sodium salt of the synthetic, pure levo T4 hormone, that is identical with the one produced by the human thyoid gland. It is particularly effective in treating individual suffering from hypothyroidism which is a condition whereby the thyroid gland is less active than normal.

Key points include:

  • Indications: These drugs are used in clients with hypothyroidism, clients with goiter and for management of thyroid cancer
  • Mechanism of Action: It helps maintain the metabolic activity of the body, as it provides the missing T4 to the appropriate tissues.
  • Administration: Comes in the form of tablet, capsule and injectable.
  • Monitoring: It has special family and patient education that involves regular blood work for level determination.

Levothyroxine sodium Statistical Development:

Thyroid hormones play a crucial role in the normal functioning of the human body, and scientists synthesized levothyroxine sodium, along with other synthetic preparations of this hormone, in the mid-20th century. These developments have significantly impacted the treatment of thyroid disorders, particularly hypothyroidism.Levothyroxine sodium 3

  • 1930’s: Synthesis of thyroxine met its first unprecedented completion.
  • 1950’s: Baby levothyroxine synthesis gets practical scope
  • 1960’s-1970’s: Getting various potencies and dosage forms to the market
  • 1980’s: Extensively using levothyroxine for the treatment of low metabolic activity of the thyroid gland.

The main objective of this research was to improve undesirabilities seen in many thyroid hormone replacement treatment at that time. This enables manufacturers to have levothyroxine sodium that has all the desirable characteristics including being stable and potent as well as bioavailable. Their synthesis has become more sophisticated over these years, enhancing efficiency and safety to the patients.

Levothyroxine sodium Chemical Composition and Properties:

Levothyroxine sodium, a artificial version of the hormone thyroxine (T4) is as L-3,3′,5,5′-tetraiodothyronine sodium salt. The molecular formula of this substance is C15H10I4NNaO4. These properties possess:

  • Molecular Weight: The molecular weight is about 798.85 g/mol.
  • Appearance: The powder resembles whitish to pale yellowish brown colors.
  • Solubility: Soluble in water, slightly soluble in ethanol but insoluble in most of the organic solvents.
  • pH: Slightly acidic to neutral conditions.
  • Stability: The product is stable within the prescribed conditions of storage.

Levothyroxine sodium is very potent and the product is light, moisture and heat sensitive.

Mechanism of Action:

Levothyroxine sodium is a synthetic form of a thyroid hormone known as thyroxine (T4). The T4 produced endogenously by the thyroid gland is further metabolised peripherally into triiodothyronine T3. Thus levothyroxine sodium has the following actions:

  • It enters into the nuclei of the cells and attaches to the thyroid hormone receptors.
  • It helps modulate the expression of genes that are necessary for normal growth and development.
  • It increases the basal metabolic rate.
  • It also modulates carbohydrate, lipid and protein metabolism.
  • It modulates growth and differentiation of tissues.

Levothyroxine-sodium replaces deficient endogenous T4 thus correcting the metabolic rates and normal physiological function of patients with hypothyroidism.

Levothyroxine sodium Indications for Use:

Levothyroxine Sodium is indicated for a variety of thyroid disorders such as:

  • Hypothyroidism: Helps in the management of primary, secondary, and tertiary hypothyroid states.
  • Goiter: Used to decrease enlargement of the thyroid gland.
  • Thyroid Cancer: Supportive therapy in management.
  • Myxedema Coma: Considered in the management as an adjunct.
  • Thyroid Function Test: As a suppression test for diagnostic purposes.
  • Subclinical Hypothyroidism: Provides treatment of milder forms of hypothyroidism with certain signs.
  • Pregnancy-related Hypothyroidism: Safe treatment for the cause of hypothyroidism during pregnancy.

Redirecting relies on medical expertise, the results of thyroid function tests, and existing co-morbidities of the patients.

Benefits and Therapeutic Uses:

It has great benefits and therapeutic uses in the management of thyroid disorders:

  • Hypothyroidism: Employed for the use in patients who lack enough thyroid hormone.
  • Thyroid Cancer: Administered after an operation to inhibit Thyroid Stimulating Hormone (TSH).
  • Goiter: Aids and partially prevents the development and reappearance of goiters.
  • Congenital Hypothyroidism: Very crucial to infants for normal growth and maturation.
  • Thyroiditis: Reduces inflammatory symptoms of the thyroid gland.

Metabolic activities of the body including and not limited to metabolic rates, thermal regulation, functioning of cardio vascular and nerve systems are some of the other functions of levothyroxine sodium beyond thyroid relations.

Levothyroxine sodium: Dosage and Administration Guidelines

Levothyroxine Sodium requires a fixed dosage in order to ensure that optimum therapeutic outcomes are realized.

  • Initial Dosage:
    • Adults: Usually begins with a dose of 25 to 50mcg per day.
    • Children: Depending on age and weight standard and modified doses are calculated.

Maintenance Dosage:

  • Adults: 1.6mcg/kgbw per day.
  • These were converted every 4 to 6 weeks depending on TSH levels.

Administration:

  • Given orally and preferably swallowed on an empty stomach.
  • The same hour of the day (usually morning) and same day each week.

Missed Dose:

  • When it is not too close to the next dose, take it as soon as possible.
  • Two doses should not be taken at the same time.

Keep watch for signs of under or overdosage.

Adverse Effects of Thyroid Hormones (Levothyroxine sodium):

Levothyroxin has several adverse reactions with:

  • Antidepressants.
  • Anticoagulants.
  • Antidiabetics.
  • Antihyperlipidemic agents.

Levothyroxine sodium: Monitoring and Adjusting Treatment

Patients on Levothyroxine Sodium are likely to have regular blood tests carried out. These patients are also supposed to carry blood tests in monitoring the levels of Thyroid Stimulating Hormone (TSH) and free thyroxin (T4) levels on a frequent basis.

Key Points:

  • Initial Testing: Typically, blood tests begin from six to eight weeks after commencement of treatment.
  • Follow-up: All patients are asked to undergo a blood test once a year or two times a year in order to maintain good thyroid function.
  • Dose Adjustments: Usually the change of speed manifests through the results of the medical investigation and accordingly dosage may need adjustment.
  • Symptoms Monitoring: Ensure that empty or full states of the body do not go unnoticed and there are no signs of over or under treatment management, for example fatigue, weight increases, or heart pounding.
  • Special Populations: Women in the family way and those with heart ailments are counselled to have closer monitoring.
  • Drug Interactions: There are some drugs that may alter how Levothyroxine works that will require changes in Levothyroxine dosage.
