Carbimazole Tablets

Availability: In stock


Neo-Mercazole tablets 5mg are used to treat hyperthyroidism or over-active thyroid, which causes thyrotoxicosis due to over production of thyroid hormone. The most common form of hyperthyroidism is Grave’s Disease or goitre, which is thought to be an autoimmune disease where autoantibodies called thyroid stimulating immunoglobulins bind to the receptor for Thyroid Stimulating Hormone (TSH) and cause loss of regulation of thyroid hormone production. Hyperthyroidism can also be caused by inflammation, a tumour or a virus infection. Symptoms of hyperthyroidism are due to increased production of thyroid hormone, which causes increased rate of metabolism. They include nervousness, restlessness, irritability difficulty concentrating, tiredness, rapid heartbeat, heat intolerance, increased perspiration, difficulty sleeping, hand tremors, weight loss, increased appetite, frequent bowel movements, and muscular weakness. Neo-Mercazole tablets 5mg are used to help induce permanent remission from thyrotoxicosis; also to restore normal thyroid function before thyroid surgery to remove whole or part of the thyroid gland; also before and after treatment with radioactive iodine for overactive thyroid.

Mechanism of action:

Neo-Mercazole tablets 5mg contain carbimazole, which is a pro-drug and is rapidly metabolised after absorption into its active form methimazole. This metabolite inhibits the action of thyroid peroxidase, an enzyme that is involved in the coupling and iodination of thyroglobulin, which is important for the synthesis of thyroid hormone. Hyperthyroidism is due to an overactive thyroid gland and overproduction of thyroid hormone, which exists in two forms, thyroxine or levothyroxine, also known as T4 and liothyronine or L-triiodothyronine also known as T3. The production of thyroid hormone is normally regulated by thyroid stimulating hormone (TSH), a hormone produced by the pituitary gland in the hypothalamus, at the base of the brain, and it is this regulation that is deficient in Grave’s disease. Carbimazole in Neo-Mercazole tablets 5mg blocks the synthesis of thyroid hormone and thereby helps restore normal levels.

Overdose produces untoward side effects on one or various organs in the body. A drug is excreted in the kidney or metabolized in the liver most of the times. This process goes without any hurdles when taken in normal dose, but when taken in an overdose, the body is not able to metabolize it or send it out properly which causes the effects of anoverdose
