Formula Information

A small arrow pointing down

Liothyronine is a synthetic form of triiodothyronine (T3), a thyroid hormone that is used to treat various conditions such as hypothyroidism, myxedema coma, and certain types of depression. It is particularly beneficial for patients who do not respond well to levothyroxine (T4) alone. Liothyronine works by replenishing the levels of thyroid hormone in the body, thereby helping to regulate the body's energy and metabolism. The 30 mcg slow-release formulation of Liothyronine, encapsulated within Methocel E4M, is designed to provide a controlled release of the hormone over an extended period. This is particularly advantageous for maintaining steady hormone levels throughout the day, which can be critical for managing symptoms effectively.

The Methocel E4M polymer used in these capsules is a high-viscosity grade hydroxypropyl methylcellulose (HPMC), which forms a gel-like matrix when it comes into contact with gastric fluids. This matrix creates a barrier that slows the release of the active ingredient, allowing for a gradual absorption into the bloodstream. This slow-release mechanism can help minimize potential side effects associated with peak doses of thyroid hormones and can also reduce the frequency of dosing, which may improve patient adherence to the treatment regimen.

For patients with hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones, the slow-release Liothyronine can help to normalize the body's metabolism, energy levels, and overall well-being. In cases of myxedema coma, a severe form of hypothyroidism, Liothyronine can be a critical component of the emergency treatment, although the slow-release form may not be appropriate in such acute settings. Additionally, Liothyronine is sometimes used as an adjunct therapy for depression, particularly when patients do not fully respond to conventional antidepressants. The controlled release of Liothyronine may provide a more consistent therapeutic effect, potentially improving mood and cognitive function over time.

It is important for prescribers to consider the individual needs of their patients when choosing a thyroid hormone replacement therapy. The slow-release Liothyronine capsules may be particularly suitable for patients who experience fluctuations in their symptoms or have difficulty maintaining stable thyroid hormone levels with immediate-release formulations. As with any medication, monitoring of thyroid function tests is essential to ensure the dose of Liothyronine is optimized for the patient's specific condition.

Patients should be advised that it may take several weeks to notice the full benefits of the medication, and they should continue to take the capsules as prescribed, even if they feel well. They should also be aware of potential side effects, which may include symptoms of hyperthyroidism such as palpitations, nervousness, or insomnia, especially if the dose is too high. Regular follow-up appointments with their healthcare provider are crucial for monitoring the effectiveness of the treatment and making any necessary dosage adjustments.

Drug Interactions

A small arrow pointing down

Liothyronine is a synthetic form of triiodothyronine (T3), a thyroid hormone used to treat hypothyroidism and certain types of goiter. It is also used in the management of thyroid cancer and as a diagnostic agent in the suppression test for mild hyperthyroidism. The slow-release formulation of liothyronine 30 mcg in Methocel E4M (hydroxypropyl methylcellulose) is designed to maintain a steady level of the hormone in the bloodstream, which is crucial for patients requiring a consistent thyroid hormone level.

When considering drug interactions, it is important to note that thyroid hormones may increase the effect of anticoagulants, such as warfarin, which could lead to an increased risk of bleeding. Patients on anticoagulant therapy should have their clotting status closely monitored, and the dosage of the anticoagulant may need to be adjusted. Additionally, liothyronine may accelerate the metabolism of corticosteroids, so patients taking both may require an adjustment in their corticosteroid dosage.

Medications such as cholestyramine, colestipol, or aluminum-containing antacids can bind thyroid hormones in the gastrointestinal tract, reducing their absorption and efficacy. To minimize this interaction, it is recommended to administer liothyronine at least 4 hours before or after these agents. Similarly, calcium and iron supplements can impair the absorption of thyroid hormones, so a separation of administration times is advised.

Diabetes medications may also require adjustment when taken with liothyronine, as thyroid hormones can increase blood sugar levels. Patients with diabetes should monitor their blood glucose levels closely, and adjustments to antidiabetic medication dosages may be necessary. Conversely, liothyronine requirements may be increased in patients taking insulin or oral hypoglycemic agents.

Some drugs, such as phenytoin, carbamazepine, and rifampin, can increase the hepatic metabolism of thyroid hormones, potentially necessitating an increase in the liothyronine dose. Conversely, other medications like beta-blockers, amiodarone, and sertraline may decrease the peripheral conversion of T4 to T3 and could alter the effectiveness of liothyronine therapy.

It is also important to be aware that liothyronine can affect the action of sympathomimetic agents, leading to increased risk of coronary insufficiency in patients with cardiovascular disease. Caution is advised when initiating or adjusting the dose of liothyronine in these patients.

Lastly, patients should be counseled to avoid foods containing soybean flour, cottonseed meal, walnuts, dietary fiber, and grapefruits, as these can affect the absorption of thyroid hormones. Consistency in the timing of medication relative to food intake can help maintain therapeutic effectiveness.

Due to the complexity of these interactions, it is essential for prescribers to review all medications, including over-the-counter drugs and supplements, that a patient is taking before initiating liothyronine therapy. Adjustments to therapy should be made based on clinical response and laboratory parameters. For any questions or concerns regarding this formulation and its interactions, please reach out to us at Bayview Pharmacy for further assistance.

How Does it Work

A small arrow pointing down

Liothyronine is a synthetic form of triiodothyronine (T3), a thyroid hormone that is naturally produced by the thyroid gland. This hormone plays a crucial role in regulating the body's metabolic rate, heart and digestive functions, muscle control, brain development, and maintenance of bones. When the thyroid gland does not produce enough T3, either due to disease, surgery, or radiation treatment, it can lead to a condition known as hypothyroidism. Liothyronine 30 mcg Slow Release (MEM4) Oral Capsules are used to treat this condition by supplementing the levels of thyroid hormone in the body, thereby helping to restore normal metabolic activity and alleviate the symptoms of hypothyroidism, such as fatigue, weight gain, and depression.

The slow-release formulation of Liothyronine 30 mcg capsules is achieved through the use of Methocel E4M, which is a type of hydrophilic polymer known as hydroxypropyl methylcellulose (HPMC). Methocel E4M swells and forms a gel when it comes into contact with gastric fluids after the capsule is ingested. This gel matrix creates a barrier through which the liothyronine must diffuse to be released. The rate of drug release is controlled by the rate at which the gastric fluid penetrates the gel and the rate at which the drug diffuses through this gel layer. This results in a more consistent and prolonged release of liothyronine into the bloodstream, which can help maintain stable hormone levels throughout the day.

By using a slow-release formulation, patients may experience fewer fluctuations in hormone levels compared to immediate-release forms of the medication. This can lead to improved symptom control and may reduce the risk of potential side effects associated with peak levels of the hormone. Additionally, the reduced dosing frequency can enhance patient compliance, as patients need to remember to take their medication less often. This is particularly beneficial for chronic conditions like hypothyroidism, where long-term medication adherence is crucial for effective management.

It is important for both patients and prescribers to understand that the dosing of Liothyronine 30 mcg Slow Release (MEM4) Oral Capsules must be individualized based on the patient's thyroid hormone levels and clinical response. Regular monitoring of thyroid function tests is necessary to ensure the dose is appropriate. If you have any questions about this formulation or how it works, please reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is here to provide the information and support you need to effectively manage hypothyroidism with this specialized medication.

Other Uses

A small arrow pointing down

The Liothyronine 30 mcg Slow Release (MEM4) Oral Capsules have been designed primarily for the management of hypothyroidism, where they help in replenishing the deficient thyroid hormone levels. The use of controlled-release Methocel E4M in these capsules ensures a consistent release of liothyronine, the synthetic form of the T3 hormone, throughout the day, which mimics the body's natural secretion patterns, potentially leading to steadier hormone levels and reduced incidence of peak-trough fluctuations that can be associated with multiple dosing schedules.

However, beyond their primary indication, these slow-release capsules might serve other therapeutic purposes. In some cases, they may be used off-label to support the treatment of certain forms of depression where conventional antidepressants have not been fully effective, and the patient may have subclinical hypothyroidism or thyroid hormone resistance. Additionally, these capsules might be utilized as an adjunct therapy in the management of myxedema coma, a rare but severe manifestation of hypothyroidism, where a gradual control of the hormone levels is critical. Moreover, there is potential use in treating certain types of thyroid cancer where T3 levels need to be managed carefully after thyroidectomy to suppress thyroid-stimulating hormone (TSH) levels without inducing hyperthyroid symptoms.

Despite the possibilities, it is crucial to note that any off-label use should be undertaken with rigorous clinical oversight and only when the benefits outweigh the risks and contraindications. Patients considering this medication for uses beyond standard hypothyroidism treatment should consult with their healthcare provider, and a thorough examination of the patient’s medical history, underlying conditions, and current medication regimen should be conducted to prevent adverse effects and ensure the safe application of this formulation.
