What is the indication of methimazole?
Pharmacology. In the United States, methimazole is indicated for the treatment of hyperthyroidism in patients with Graves’ disease or toxic multinodular goiter for whom thyroidectomy or radioactive iodine therapy are not appropriate treatment options.
What is Tapazole used to treat?
Methimazole is used to treat overactive thyroid (hyperthyroidism). It works by stopping the thyroid gland from making too much thyroid hormone.
What should I monitor with Tapazole?
Lab Test Considerations:
- Monitor WBC and differential counts periodically during therapy.
- May cause ↑ AST, ALT, LDH, alkaline phosphatase, serum bilirubin, and prothrombin time.
Why is methimazole preferred over propylthiouracil?
Methimazole — Methimazole is usually preferred over propylthiouracil because it reverses hyperthyroidism more quickly and has fewer side effects. Methimazole requires an average of six weeks to lower T4 levels to normal and is often given before radioactive iodine treatment.
Why is PTU preferred over methimazole in thyroid storm?
PTU or carbimazole (or methimazole) can be used, but PTU was traditionally preferred because of its more rapid onset of action and the additional benefit of inhibition of peripheral deiodinase enzyme-mediated conversion of T4 into T3.
What is the difference between Tapazole and methimazole?
Methimazole (brand names: Tapazole®, Felimazole®) is an antithyroid medication used to treat hyperthyroidism in cats.
What is the action of carbimazole?
Carbimazole is one of several thionamide drugs used in the treatment of hyperthyroidism. It works by inhibiting the thyroid peroxidases (TPO) that catalyze the iodination of tyrosine residues in thyroglobulin and the oxidative coupling of iodinated tyrosines.
What is the action of methimazole?
Mechanism of Action Methimazole directly interferes with the first step in thyroid hormone biosynthesis in the thyroid gland. By acting as a substrate for the catalyst thyroid peroxidase, methimazole inhibits the incorporation of iodide into the thyroid hormone precursor, thyroglobulin.
What should I monitor with methimazole?
Because methimazole may cause hypoprothrombinemia and bleeding, prothrombin time should be monitored during therapy with the drug, especially before surgical procedures. Thyroid function tests should be monitored periodically during therapy.
What are the side effects of Tapazole?
Common side effects may include:
- nausea, vomiting, upset stomach;
- headache, dizziness, drowsiness;
- numbness or tingly feeling;
- rash, itching, skin discoloration;
- muscle or joint pain;
- hair loss; or.
- decreased sense of taste.
Which is safer PTU or methimazole?
Antithyroid drugs during pregnancy — Propylthiouracil is the drug of choice during the first trimester of pregnancy because it causes less severe birth defects than methimazole.
