Umifenovir is a potent, orally active broad-spectrum antiviral agent with activity against enveloped and non-enveloped viruses, suppressing virus propagation and modulating the expression of inflammatory cytokines for use as an anti-influenza virus agent [3]. It effectively inhibits the fusion of the virus with host cells [1] [2] and is an efficient inhibitor of SARS-CoV-2 in vitro [2].

| In vitro | Arbidol exhibits potent antiviral activity against a wide range of viruses, including influenza viruses A, B, and C, respiratory syncytial virus, SARS-CoV, adenovirus, parainfluenza type 5, poliovirus 1, rhinovirus 14, coxsackievirus B5, hantaan virus, Chikungunya virus, HBV, and HCV.[1] |
| In vivo | Arbidol (25 and 45 mg/ml; p.o.; 6–8 weeks old BALB/c mice) shows a survival benefit to mice suffering from influenza infection. Increased the survival rate, inhibited the decrease of body weight at 45 mg/mL, and inhibited the increase of mice lung index at 25 mg/mL and 45 mg/mL compared to the virus group.[3] |
