A subsequent pilot study of six COVID-19 patients, who were shedding the virus from the nose, looked at whether the laboratory results translated to people.
The trial showed that a single Nasodine dose (four sprays per nostril) reduced viral shedding in five of the six subjects (83 per cent) at five minutes after the dose, with an overall 79 per cent reduction in viral shedding at one hour after the dose.
