Antiviral effect of Ribavirin drugs and RTP-Nanogel formulation in MDCK cells infected with influenza A virus. Cytopathic effect (Δ) of virus was initially determined (A) and dose-dependent curves obtained using 96-well microplate MTT assay (B). These curves were used to determine an effective inhibitory concentration (EC90) and cytotoxicity (CC90). Selectivity index (SI) was calculated as CC90/EC90.
