Propycil® 50 mg Tablet (Propylthiouracil) for Hyperthyroidism Treatment

Propycil® 50 mg Tablet contains propylthiouracil, a medication used to treat hyperthyroidism, a condition in which the thyroid gland produces excessive thyroid hormones.

Propylthiouracil works by reducing the production of thyroid hormones in the thyroid gland. As a result, it helps restore normal hormone levels in the body. Consequently, symptoms such as rapid heartbeat, weight loss, sweating, and nervousness gradually improve.

Doctors often prescribe Propycil tablets to manage Graves’ disease, toxic multinodular goiter, and other forms of hyperthyroidism. In addition, the medicine may help control thyroid hormone levels before thyroid surgery or radioactive iodine therapy.

Patients take this medication orally (by mouth) as prescribed by a healthcare professional.

Composition

Each tablet contains:

• Propylthiouracil – 50 mg

The tablet may also contain inactive ingredients (excipients) that help maintain stability and support tablet formulation.

Mechanism of Action

Propylthiouracil belongs to a group of medicines called antithyroid agents.

The medicine works by inhibiting the production of thyroid hormones in the thyroid gland. It blocks the enzyme responsible for converting iodine into active thyroid hormones. Consequently, the formation of thyroxine (T4) and triiodothyronine (T3) decreases.

Additionally, propylthiouracil reduces the conversion of T4 to the more active hormone T3 in peripheral tissues.

This dual action helps:

• Lower excess thyroid hormone levels

• Control symptoms of hyperthyroidism

• Support the restoration of normal metabolic balance

Indications

Doctors prescribe Propycil® 50 mg Tablet for the treatment and management of:

• Hyperthyroidism

• Graves’ disease

• Toxic multinodular goiter

• Preparation before thyroid surgery

• Management before radioactive iodine therapy

However, doctors determine treatment based on clinical evaluation and thyroid hormone levels.

Dosage and Administration

Doctors determine the dosage based on the severity of hyperthyroidism and the patient’s response to treatment.

Treatment usually begins with a higher initial dose to control hormone levels. After improvement, doctors gradually reduce the dose to a maintenance level.
