"Propylthiouracil" Natural Recordings by Native Speakers
Propylthiouracil (PTU) is a synthetic antithyroid medication used to treat hyperthyroidism, a condition where the thyroid gland produces excessive amounts of thyroid hormones.
It works by:
1. Inhibiting the synthesis of thyroid hormones: PTU blocks the enzyme thyroid peroxidase (TPO), which is necessary for the conversion of iodine into thyroid hormones.
2. Reducing the release of thyroid hormones: PTU also decreases the release of pre-formed thyroid hormones from the thyroid gland.
By doing so, PTU slows down the production of thyroid hormones in the body, thereby reducing the symptoms of hyperthyroidism.

To distribute or divide something in proportion to the amount used or the period of time, especially in relation to a particular service or expense; to share or charge something according to certain rules or qualifications.<br><br>Example: The school prorated the bus fare for the students, so those who rode for only half the semester only paid half price.

Prorations refer to a partial refund or partial payment of a fee or installment, especially in cases where an individual or entity is leaving a service, such as a lease or a contract, before their expected end date.
