Pirodavir

Pirodavir inhibits 80 percentage of viruses at 0.064 micrograms/ml(EC80). Pirodavir is a novel capsid-binding antipicornavirus agent with potent in vitro activity against both group A and group B rhinovirus serotypes. Pirodavir was effective in preventing experimentally induced RV illness. Intranasal sprays of pirodavir were associated with significant antiviral effects but no clinical benefit in treating naturally occurring rhinovirus colds.
