Drug loss to intravenous filters is minimal for vancomycin and phenobarbitone in adults. Tobramycin shows moderate binding to filters, potentially impacting adult patient dosing.

Area of Science:

  • Pharmacology
  • Drug Delivery Systems

Context:

  • Intravenous drug administration commonly utilizes in-line filters.
  • The potential for drug adsorption to these filters can affect administered doses.

Purpose:

  • To quantify the in vitro loss of tobramycin, vancomycin, and phenobarbitone to in-line filters.
  • To compare drug binding to new versus used filters and assess the impact of administration methods (bolus vs. continuous).

Summary:

  • Drug binding to in-line filters was higher with new filters compared to used ones.
  • Tobramycin exhibited the highest adsorption, with concentrations reduced by 7% (used filters) to 12% (new filters) during bolus administration.
  • Vancomycin and phenobarbitone showed minimal loss (1-4%), suggesting negligible clinical impact in adult patients.

Impact:

  • Tobramycin adsorption to intravenous filters is moderately significant for adult patients, potentially requiring dose adjustments.
  • Adsorption of vancomycin and phenobarbitone to in-line filters is not clinically relevant in adult patients.
  • Findings suggest filter saturation may reduce drug binding over time.
