What is the connection between synthroid and cytomel?

Synthroid® and Cytomel® are synthetic copies of two thyroid hormones known as T4 and T3. T4 and T3 are made by the thyroid gland, which is located in the throat. In a state known as hypothyroidism, the thyroid ceases to function and the body does not receive enough thyroid hormones. Because thyroid hormones are involved in the regulation of metabolism and energy, there may be a lack of symptoms such as weight gain, fatigue, dry skin and constipation. Hydroid drugs such as Synthroid® and Cytomel® can be used to treat hypothyroidism.

Drug Synthroid® is an artificial copy of the T4 thyroid hormone, also known as tetraiodothyronine. The T4 is produced by the thyroid gland in response to the hormone stimulating thyroid or TSH, which is released by pituitary gland in the brain, along with a small amount of T3 or triodothyronine. T3 is an active thyroid hormone and T4 is converted into T3 in body tissues where it acts on cells. Cytomel®je synthetic T3 form. While in the treatment of thyroid diseaseSynthroid® and Cytomel® can be used, synthetic T4 versions are the most commonly used treatment of hypothyroidism.

Synthroid® and Cytomel® can replace thyroid hormones that are needed to regulate the chemical processes taking place inside living cells. In a state known as hypothyroidism, the lack of sufficient thyroid hormones leads to symptoms that indicate the slowing of the body, mentally and physically. Because the body is usually able to convert T4 into T3, in many cases copies of T4, such as Synthroid®, can be used to treat hypothyroidism.

Since the T4 remains in the blood for a long time, it creates an effect for several days, T3 drugs such as cytomel® are sometimes used instead when sudden changes in treatment are required. This is an example of this in the preparation for radioisotope imaging studies on the thyroid, if it is necessary to stop the drugs before the test. T3 remains in the body for up to 24 hours only in the body, soThe advantage of cytomel® vs Synthroid® is that the doses can be adjusted relatively quickly. The advantage of using Synthroid® vs Cytomel® is that the dose is likely to remain at a constant level because the drug remains in the body longer. Synthroid® is believed to have a lower risk of side effects affecting hearts.
