This study shows that a combination of betamethasone, iopanoic acid, and propranolol is a safe and effective short-term preoperative treatment for hyperthyroid patients undergoing thyroidectomy. The regimen rapidly improved clinical symptoms and hormonal levels with excellent drug tolerance.

Area of Science:

  • Endocrinology
  • Surgical Preparation
  • Pharmacology

Background:

  • Hyperthyroid patients often require surgery, necessitating effective preoperative management.
  • Traditional antithyroid drugs may fail or be contraindicated in certain patient populations.
  • An alternative, rapid preoperative regimen is needed for urgent or non-compliant cases.

Purpose of the Study:

  • To evaluate an alternative preoperative regimen for hyperthyroid patients using betamethasone, iopanoic acid, and propranolol.
  • To assess the safety, efficacy, and patient acceptability of this combined drug therapy.
  • To determine the impact on clinical status, hormonal levels, and surgical outcomes.

Main Methods:

  • A 5-day oral regimen of betamethasone, iopanoic acid, and propranolol was administered.

  • Subtotal thyroidectomy was performed on the 6th day for 14 patients with refractory hyperthyroidism.
  • Clinical assessments and serum T3, T4, and rT3 levels were monitored daily.

    • Main Results:

    • Patients achieved clinical euthyroid status by day 5.
    • Significant reductions in T3 levels were observed within 24 hours, with further decreases by surgery.
    • T4 levels showed a slight decrease, while rT3 levels increased significantly.
    • The regimen was well-tolerated, with no serious side effects, even in pregnant patients.
    • No anesthetic or postoperative complications occurred, with rapid patient discharge.

    Conclusions:

    • The combination of betamethasone, iopanoic acid, and propranolol is a safe, effective, and low-cost preoperative treatment for hyperthyroid patients.
    • This regimen is suitable for urgent thyroidectomy cases or patients requiring a short preoperative course.
    • Adequate patient supervision is crucial for successful implementation.
