Product Name: T3 (Liothyronine Sodium)
Active Ingredient:
Liothyronine Sodium (T3)
Description:
Liothyronine sodium (T3) is a synthetic form of the thyroid hormone triiodothyronine, which plays a crucial role in regulating metabolism, energy production, and the development of the central nervous system. T3 is involved in the control of protein synthesis, carbohydrate metabolism, and fat metabolism. The medication is commonly prescribed for hypothyroidism, a condition where the thyroid does not produce sufficient thyroid hormones. T3 is more potent and has a faster onset of action compared to thyroxine (T4), another thyroid hormone.
Quantitative and Qualitative Composition:
- Active Substance: Each tablet contains 25 μg of liothyronine sodium (T3).
- Excipients: Lactose, cellulose, magnesium stearate, and other excipients.
Pharmaceutical Form:
White, round tablets for oral administration.
Packaging:
100 tablets per container.
Pharmacotherapeutic Classification:
Thyroid hormones (ATC Code: H03AA01)
Therapeutic Indications:
- Hypothyroidism: T3 is primarily used in the treatment of hypothyroidism (underactive thyroid), where the thyroid gland produces insufficient thyroid hormones. It helps normalize thyroid hormone levels and restore normal metabolic function.
- Thyroid Hormone Replacement Therapy: T3 can be used as part of thyroid hormone replacement therapy for individuals with thyroid disorders such as Hashimoto’s thyroiditis, following thyroidectomy, or in other conditions causing thyroid hormone deficiency.
- Off-label Uses: T3 is sometimes used off-label for weight loss or fat burning, although its use for this purpose is controversial and should only be under medical supervision due to potential risks.
Dosage and Administration:
The dosage of T3 varies depending on the condition being treated:
- For hypothyroidism: The usual starting dose is 25 μg per day, which may be increased gradually depending on the patient’s response and thyroid hormone levels. The typical maintenance dose ranges from 25–75 μg per day.
- Thyroid hormone replacement: Doses are individualized based on thyroid function tests, and the goal is to achieve a euthyroid state (normal thyroid function).
- Off-label use (e.g., for weight loss): Doses vary and should be prescribed with caution. The use of T3 for fat loss should be supervised by a healthcare provider, as improper use can lead to serious side effects.
