Non-steroidal anti-inflammatory drugs (NSAIDs) like aceclofenac can alter thyroid hormone binding. Aceclofenac significantly changed triiodothyronine (T3) binding to thyroxine-binding globulin (TBG), impacting thyroid hormone distribution.

Area of Science:

  • Endocrinology
  • Pharmacology

Context:

  • Non-steroidal anti-inflammatory drugs (NSAIDs) are known to influence thyroid hormone levels.
  • The mechanism often involves interference with thyroid hormone binding proteins.

Purpose:

  • To investigate the acute effects of a single aceclofenac dose on thyroid function and hormone binding.
  • To analyze changes in free thyroid hormones (FT3, FT4) and thyrotropin (TSH) serum levels.
  • To assess alterations in thyroid hormone binding to plasma proteins.

Summary:

  • A single dose of aceclofenac was administered to 18 healthy volunteers.
  • Thyroid hormone binding was assessed using horizontal agarose-gel electrophoresis.
  • Aceclofenac significantly decreased triiodothyronine (T3) binding to thyroxine-binding globulin (TBG) and increased albumin-bound T3.

Related Experiment Videos

  • Free T3, free T4, and TSH levels showed no significant changes.

    • Impact:

    • Aceclofenac induces a significant redistribution of T3 protein binding.
    • This effect is likely due to the displacement of T3 from TBG by aceclofenac.
    • Highlights potential interactions between NSAIDs and thyroid hormone homeostasis.
