Levothyroxine Sodium 75 mcg/Liothyronine 10 mcg Oral Capsules

Levothyroxine Sodium 75 mcg/Liothyronine 10 mcg Oral Capsules are a solid dosage form consisting of two gelatin or vegetarian shells that encapsulate a combination of thyroid hormones. This precise formulation is designed for ease of swallowing and ensures accurate dosing of the active ingredients. Levothyroxine Sodium is a synthetic form of the thyroid hormone thyroxine (T4), while Liothyronine is the synthetic form of triiodothyronine (T3).

This medication is specifically indicated for the treatment of hypothyroidism, a condition where the thyroid gland does not produce sufficient thyroid hormones. It is also used in the management of thyroid cancer and in some cases, for the treatment of goiter and thyroid nodules. By providing both T4 and T3, the capsules help in restoring the normal balance of thyroid hormones in the body.

Formula Information

A small arrow pointing down

Levothyroxine Sodium 75 mcg/Liothyronine 10 mcg Oral Capsules are a specialized compounded medication designed to provide a precise dose of thyroid hormones for patients requiring thyroid hormone replacement therapy. This solid dosage form consists of two halves of either gelatin or vegetarian capsules that are filled with the active ingredients, levothyroxine sodium and liothyronine, and then sealed together. The capsules are intended to be swallowed whole, offering a convenient method of administration for patients.

Levothyroxine sodium is a synthetic form of thyroxine (T4), a hormone normally produced by the thyroid gland. It is the standard treatment for hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. Liothyronine is the synthetic form of triiodothyronine (T3), another hormone produced by the thyroid gland. The combination of levothyroxine and liothyronine in these capsules is used to provide a more comprehensive replacement therapy by supplying both T4 and T3, which can be beneficial for patients who do not adequately convert T4 to T3.

This compounded formulation is particularly useful for patients who have specific dosage requirements that are not met by commercially available medications. It also benefits those who may have allergies or sensitivities to certain excipients found in standard formulations. By compounding these medications into a single capsule, patients are able to take one pill instead of multiple, simplifying their medication regimen and potentially improving adherence to treatment.

The precise dosing of levothyroxine and liothyronine in these capsules is critical, as thyroid hormones have a narrow therapeutic index. The dosages must be individualized based on the patient's thyroid hormone levels, which are monitored through blood tests. It is important for prescribers to work closely with compounding pharmacists to determine the appropriate dose for each patient.

Patients and prescribers considering this formulation should be aware that consistent and correct dosing is essential for managing thyroid hormone levels and ensuring the effectiveness of the therapy. Regular monitoring and adjustments may be necessary, especially during the initial phase of treatment or when changing the dose.

Drug Interactions

A small arrow pointing down

Levothyroxine Sodium and Liothyronine are thyroid hormones used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. Levothyroxine is a synthetic form of thyroxine (T4), while Liothyronine is a synthetic form of triiodothyronine (T3). Together, they work by replacing or supplementing the natural thyroid hormones in the body, helping to regulate the body's energy and metabolism.

When taking Levothyroxine Sodium and Liothyronine, it is important to be aware of potential drug interactions that can affect the efficacy of the medication or cause adverse effects. Certain medications can decrease the absorption of thyroid hormones, such as calcium carbonate, ferrous sulfate (iron), and antacids containing aluminum or magnesium. To minimize this interaction, these medications should be taken at least 4 hours before or after the thyroid medication.

Other drugs, like estrogen-containing products, bile acid sequestrants (e.g., cholestyramine, colestipol), and ion exchange resins (e.g., sevelamer), can also affect thyroid hormone levels and may necessitate dosage adjustments. Medications such as amiodarone, lithium, and anti-thyroid agents (e.g., methimazole, propylthiouracil) can affect thyroid function and should be used cautiously in patients receiving thyroid hormone therapy.

Additionally, certain antidepressants, sympathomimetics, and ketamine may increase the effects of thyroid hormones, leading to symptoms of hyperthyroidism or increased cardiac stimulation. Conversely, medications like beta-blockers may decrease the effects of thyroid hormones. Blood thinners (anticoagulants) such as warfarin may have their effects enhanced by thyroid hormones, increasing the risk of bleeding; therefore, close monitoring and possible dose adjustments are necessary.

It is also important to note that foods containing soybean flour, cottonseed meal, walnuts, dietary fiber, and grapefruit juice may decrease the absorption of thyroid hormones. Patients should maintain a consistent diet and be aware of these potential interactions.

Patients should inform their healthcare provider of all medications, supplements, and over-the-counter products they are taking to ensure proper management of potential interactions. Regular monitoring of thyroid function tests is recommended to adjust the dose of Levothyroxine Sodium and Liothyronine as needed.

For any questions or concerns regarding this formulation or its interactions with other drugs, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide guidance and support to ensure safe and effective treatment with Levothyroxine Sodium and Liothyronine Oral Capsules.

How Does it Work

A small arrow pointing down

Levothyroxine Sodium and Liothyronine are synthetic forms of thyroid hormones used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones. Levothyroxine Sodium is a synthetic version of thyroxine (T4), while Liothyronine is a synthetic form of triiodothyronine (T3). These hormones are crucial for maintaining the body's metabolism, heart, and digestive function, muscle control, brain development, and bone maintenance.

When a patient has hypothyroidism, their metabolism slows down due to a lack of thyroid hormones. This can lead to symptoms such as fatigue, weight gain, cold intolerance, and depression. By providing the body with synthetic hormones, Levothyroxine Sodium and Liothyronine help to restore normal metabolic activity. Levothyroxine Sodium is converted into Liothyronine in the body, which is the more active form of the hormone and is responsible for providing the necessary metabolic rate boost.

The formulation of Levothyroxine Sodium 75 mcg/Liothyronine 10 mcg Oral Capsules is designed to deliver a precise dose of these hormones in a solid dosage form. The capsules are composed of two gelatin or vegetarian shells that enclose the medication. This design allows for the medication to be swallowed easily and ensures that the active ingredients are protected until they reach the stomach, where they can be absorbed into the bloodstream. The use of capsules also allows for a more precise dosage compared to other forms such as tablets, which may need to be split.

It is important for patients and prescribers to understand that the balance of T4 and T3 provided by this formulation is critical and should be tailored to the individual's needs. The ratio of Levothyroxine Sodium to Liothyronine in this formulation is designed to mimic the natural production of thyroid hormones in the body, which is roughly 14:1 in favor of T4. This combination therapy can be particularly beneficial for patients who do not respond adequately to Levothyroxine alone.

For optimal results, the capsules should be taken on an empty stomach, typically 30 minutes to an hour before breakfast. This ensures that the hormones are absorbed as efficiently as possible. Consistency in the timing of the dose is also important to maintain stable hormone levels throughout the day. Adjustments to the dosage should be made based on regular monitoring of thyroid function tests by a healthcare provider.

If you have any questions or require further information about this formulation and its use in treating hypothyroidism, please reach out to us at Bayview Pharmacy.

Other Uses

A small arrow pointing down

Levothyroxine sodium and liothyronine are synthetic forms of thyroid hormones that are primarily used in the management of hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormones. The combination of these two active ingredients is designed to provide both immediate and long-term replenishment of thyroid hormones in the body, making the oral capsules comprehensive for managing this condition.

Aside from their use in treating hypothyroidism, there could be potential off-label uses for this formulation under the guidance of a healthcare provider. For instance, it may be prescribed to patients who have undergone thyroidectomy (surgical removal of the thyroid gland) and in cases of thyroid cancer, where suppression of thyroid stimulating hormone (TSH) is necessary. Moreover, it is sometimes used in the treatment of myxedema coma, a severe form of hypothyroidism; however, in such cases, the route of administration may differ to achieve rapid therapeutic effects.

It is essential to emphasize that levothyroxine sodium and liothyronine capsules are not recommended for the treatment of obesity or for weight loss. Using thyroid hormones in normal euthyroid patients with the intent to achieve weight loss can lead to serious or life-threatening toxicity.

The formulation might be considered when a patient presents with both hypothyroidism and specific challenges with standard therapy that might warrant a compounded solution. This could include an inability to tolerate certain excipients contained in commercial products, a requirement for precise custom dosing outside the range of commercially available products, or allergic reactions to non-active ingredients in standard formulations. The encapsulated form is particularly suitable for patients who prefer not to take liquid medications or who require a combination of different drugs in one single dose.

Patient guidance is critical when taking levothyroxine sodium and liothyronine oral capsules. The medication should be taken at least 30 to 60 minutes before breakfast to enhance absorption. Consistent daily dosing is crucial for maintaining stable thyroid hormone levels. As with all medications, it is important to consult with a healthcare provider before starting, stopping, or changing the dose of the medication.

If you have any questions or would like further information about this formulation, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of experienced compounding pharmacists is here to provide personalized care and ensure that your medication needs are met safely and effectively.
