Experimental treatment of recurrent otitis externa

The aim of this research is to determine the effect of the hybrid material based on polyvinyl alcohol and silver nanoparticles (PVA/AgNps) in the treatment of the otitis externa as an additional component in the commercial product Betazon Trio. It was established that the experimental creamy formula with silver concentration 600 mg/L is suitable for recovery of the microbial homeostasis when it is administrated once daily in dose 1 ml over a period of 14 days.
