Evidence and Efficacy

In Vitro

In vitro log10 reduction antimicrobial efficacy testing was conducted on PrevahexCHX®. A broad spectrum of microorganisms were tested, including gram-positive bacteria, gram-negative bacteria and yeasts as well as several drug-resistant microorganisms. The pathogenic microorganisms included in this study were specifically selected due to their clinical relevance and prevalence as the cause of challenging Healthcare-Associated Infections (HAIs). Antimicrobial efficacy was evaluated at 1-, 3- and 7-day timepoints and PrevahexCHX® consistently achieved a 5.0 log10 or greater reduction at all time points demonstrating ≥10x the antimicrobial performance requirements established by the FDA.

PrevahexCHX® has efficacy of over 5.0 log10 reduction against several multidrug-resistant microorganisms, the pathogens responsible for some of the most difficult-to-treat HAIs facing clinicians today. In contrast, the market leading standard transparent thin film dressing offers no antimicrobial protection to patients.

PrevahexCHX® demonstrates rapid onset of action starting at day 1 and continuing through day 7, thus dramatically outperforming other competitive antimicrobial dressings which can take several days to demonstrate significant efficacy.
