Phenoxyethanol absorption by polyvinyl chloride.

M G Lee

    Journal of Clinical and Hospital Pharmacy
    |December 1, 1984
    PubMed
    Summary
    This summary is machine-generated.

    Phenoxyethanol is absorbed by polyvinyl chloride (PVC) medical devices during irrigation, potentially reducing drug effectiveness by up to 20%. This absorption also softens the plastic, compromising device integrity.

    Area of Science:

    • Pharmaceutical science
    • Materials science

    Background:

    • Continuous irrigation therapy is a common medical procedure.
    • Polyvinyl chloride (PVC) administration sets are frequently used in healthcare settings.

    Purpose of the Study:

    • To investigate the interaction between phenoxyethanol and PVC administration sets.
    • To quantify the potential loss of phenoxyethanol potency due to absorption.
    • To assess the impact of phenoxyethanol absorption on the physical properties of PVC.

    Main Methods:

    • Continuous irrigation therapy simulation using PVC administration sets.
    • Analysis of phenoxyethanol concentration in the perfusate.
    • Mechanical testing of PVC components after drug exposure.

    Main Results:

    Related Experiment Videos

    • Phenoxyethanol was significantly absorbed by PVC administration sets.
    • Up to 20% loss of phenoxyethanol potency was observed, varying with administration conditions.
    • Absorption led to softening and reduced rigidity of the PVC luer-lock fittings.

    Conclusions:

    • PVC administration sets can absorb phenoxyethanol, impacting therapeutic efficacy.
    • The physical integrity of PVC components may be compromised by phenoxyethanol exposure.
    • Careful consideration of material compatibility is necessary for drug administration devices.
