Abstract
The present invention relates to novel stabilized silver ion complexes having improved stability in aqueous solutions. The described stabilized silver-ion complex compositions comprise a silver-thiosulfate ion complex, a sulfite stabilizing agent either with or without a sulfite preservation agent. These carrier-free aqueous sulfite stabilized silver thiosulfate ion complex compositions have improved stability when exposed to an aqueous environment for extended periods. Consequently, these compositions have improved antibacterial, anti-viral and/or antifungal activity. These stabilized compositions can be used to coat a wound dressing, an ostomy appliance, an incontinence device, or other medical devices and impart long-term antimicrobial activity.
