Bio-Decontamination Cycle Development Study: Comparative Evaluation Of Nebulized Hydrogen Peroxide (NHP) And Vaporized Hydrogen Peroxide (VHP) For Pharmaceutical Isolator Decontamination

Validating aseptic bio-decontamination is essential for maintaining strict sterility assurance in isolator operations. A comparative evaluation between Nebulized Hydrogen Peroxide (NHP) and Vaporized Hydrogen Peroxide (VHP) highlights key performance differences across parametric cycle configurations using Biological Indicators and Enzyme Indicators. While both methods achieve complete microbial inactivation, NHP demonstrates significant efficiency gains, delivering a minimum effective cycle time under 29 minutes compared to 36 minutes for VHP. Strategic evaluation reveals that injection dosage, dwell times, and chamber airflow dynamics heavily impact localized sporicidal coverage, particularly around challenging internal geometries.
