Thyrotropin, also known as thyroid stimulating hormone (TSH), is a pituitary-derived glycoprotein hormone that regulates the production of thyroid hormones by the thyroid gland. Recombinant human TSH (rhTSH) is approved for use as a diagnostic agent in the follow-up of patients with thyroid cancer and to increase iodine uptake during radioactive iodine imaging or ablation. It is not used for replacement therapy, but as a diagnostic or adjunct therapy agent.
Pharmacokinetics
No human pharmacokinetic parameters were found in published literature for recombinant human TSH (thyrotropin) administered intramuscularly or intravenously. The following are approximations based on known properties of glycoprotein hormones of similar size and descriptive information from product labels in adult patients with differentiated thyroid cancer.
