🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is rapidly absorbed from the gastrointestinal tract after oral administration. However, because it is a prodrug, it is converted to its active metabolite, methimazole, which is responsible for the therapeutic effect. The bioavailability of carbimazole is not well established from the available information, but it is considered to be well absorbed.
DistributionAfter absorption, this medicine is converted to methimazole, which is distributed widely throughout the body, including into the thyroid gland. Methimazole crosses the placenta and is distributed into breast milk. The volume of distribution is not well established from the available information.
Protein BindingMethimazole, the active metabolite of this medicine, is not significantly bound to plasma proteins. The protein binding of carbimazole itself is not established from the available information.
MetabolismThis medicine is a prodrug that is rapidly and almost completely metabolized in the liver to methimazole, which is the active form. The conversion is thought to occur via hepatic enzymes, although the specific enzymes involved are not fully established from the available information. Methimazole is then further metabolized, but the exact pathways are not well defined.
Half-LifeThe elimination half-life of methimazole, the active metabolite of this medicine, is approximately 4 to 6 hours. The half-life of carbimazole itself is not established from the available information.
ExcretionThis medicine and its metabolites are primarily excreted in the urine. The exact proportion of unchanged drug and metabolites excreted in urine and feces is not well established from the available information.
BioavailabilityThe bioavailability of this medicine is not well established from the available information, but it is considered to be well absorbed after oral administration.
Onset of ActionThe onset of action of this medicine is gradual. It may take 1 to 2 weeks for the first effects on thyroid hormone levels to be observed, and several weeks for full clinical improvement.
Peak Plasma TimeThe peak plasma time of methimazole, the active metabolite of this medicine, is approximately 1 to 2 hours after oral administration. The peak plasma time of carbimazole itself is not established from the available information.
Duration of ActionThe duration of action of this medicine is related to its effect on thyroid hormone synthesis. Because it does not affect stored hormones, the full effect develops over weeks and persists as long as the medicine is taken. After stopping, thyroid hormone levels may rise again within days to weeks.

How It Works

This medicine works by inhibiting the enzyme thyroid peroxidase, which is essential for the production of thyroid hormones. Specifically, it blocks the incorporation of iodine into tyrosine residues on thyroglobulin, preventing the formation of monoiodotyrosine and diiodotyrosine, which are precursors to thyroxine (T4) and triiodothyronine (T3). Additionally, this medicine may have some immunosuppressive effects that help reduce the production of thyroid-stimulating antibodies in Graves' disease. As a result, the levels of active thyroid hormones in the blood decrease over time, alleviating the symptoms of hyperthyroidism. This medicine does not affect the release of already-formed thyroid hormones, so the full therapeutic effect may take several weeks to become apparent.

Mechanism Steps

1
Inhibition of thyroid peroxidase: This medicine inhibits the enzyme thyroid peroxidase, which is responsible for oxidizing iodide and incorporating it into tyrosine residues on thyroglobulin.
2
Blockade of iodination: By inhibiting thyroid peroxidase, this medicine prevents the formation of monoiodotyrosine and diiodotyrosine, the building blocks of thyroid hormones.
3
Reduced hormone synthesis: As a result, the synthesis of thyroxine (T4) and triiodothyronine (T3) is decreased, leading to lower levels of these hormones in the bloodstream.
4
Immunomodulatory effect: This medicine may also suppress the immune system's production of thyroid-stimulating antibodies, which are responsible for Graves' disease, contributing to its long-term benefit.
5
Clinical improvement: Over several weeks, the reduced hormone levels lead to improvement in symptoms of hyperthyroidism such as rapid heart rate, anxiety, and weight loss.
