Nasal inhalation of antiviral microparticulate powders to target early infection of upper airways

Sniffing a nasal antiviral powder could timely treat the patient and prevent disease worsening to pneumonia. It is also not unrealistic that the loco-regional antiviral action might reduce the contagiousness of infected subjects. Looking ahead, the studied nasal powder prototypes meet the patient need to find in retail pharmacy an active and safe medicine for use at home, promptly prescribed by the general practitioner at first infection symptoms. To use such a product, the patients will only need to be trained by the pharmacist to perform the correct nasal inhalation maneuver.
