SinoFresh nose spray controls MRSA in vivo

USA-based SinoFresh HealthCare has reported preliminary results from an in vivo pilot study indicating that its patented SinoFresh nasal spray was shown to be useful in controlling methicillin-resistant Staphylococcus aureus in the nasal passages.

According to the firm, these favorable efficacy results follow an earlier, successful in vitro study that was conducted at the US Public Health Research Institute under the direction of Barry Kreiswirth, director of the Tuberculosis Center and Hospital Infections Program.

The study showed that "SinoFresh nasal spray used three times daily appeared to effectively eliminate MRSA in the noses of the test animals while leaving enough normal microbes to keep a normal population in the nasal passages," according to John Todhunter, consultant to SinoFresh, who oversaw the study, which was conducted at Virion Systems in Rockville, Maryland, USA.
