Response of Influenza Virus-Infected Mice to Selected Doses of Ribavirin Administered Intraperitoneally or by Aerosol

Abstract
The effects of graded doses of ribavirin administered either by aerosol or intraperitoneally were compared in influenza virus-infected mice. The median effective dose values (based upon percent survival) were 3.3 and 15.8 mg/kg per day for the aerosol and intraperitoneal routes, respectively. Lung lesion scores and titer of virus were lower after aerosol than intraperitoneal therapy.
