Area of Science:

  • Analytical Chemistry
  • Clinical Chemistry
  • Pharmacology

Background:

  • Coulometric titration is a precise and accurate method for quantifying iron in liquid samples.
  • This technique is known for its minimal analytical interferences compared to colorimetric methods.

Purpose of the Study:

  • To investigate potential drug interferences with the coulometric determination of serum iron.
  • To highlight the importance of systematically studying drug effects on analytical methods.

Main Methods:

  • Utilized coulometric measurement technique for serum iron determination.
  • Administered specific drugs (chondroitin iron sulfate, deferoxamine mesylate, salazosulfapyridine) to assess their impact.

Main Results:

  • Demonstrated significant positive effects of tested drugs on serum iron measurements.
  • Identified chondroitin iron sulfate, deferoxamine mesylate, and salazosulfapyridine as potential interferents.

Conclusions:

  • Drug-induced analytical interferences can compromise the accuracy of serum iron measurements.
  • Systematic evaluation of new drugs and analytical methods for interferences is crucial for reliable clinical and pharmacological assessments.
