Brief Summary:
The purpose of this study is to determine whether Arbidol (Umifenovir) is effective in the treatment and Prophylaxis of Influenza and Common Cold

Condition or disease Intervention/treatment Phase
Influenza Drug: Arbidol (Umifenovir) Other: placebo Phase 4

Detailed Description:
Influenza virus infections result in major health and economic burdens worldwide. The World Health Organization estimates that the average global burden of interpandemic influenza is approximately 1 billion cases of influenza, from 3 to 5 million cases of severe illness, and from 300 000 to 500 000 deaths annually. Arbidol (Umifenovir) is currently licensed for the treatment and prevention of influenza in Russian Federation. Arbidol (Umifenovir) has a direct antiviral effect. Arbidol (Umifenovir) belongs to fusion inhibitors; it interacts with the virus hemagglutinin and thus prevents fusion of the viral envelope with cell membranes. The aim of the study is to obtain additional data on safety and therapeutic efficacy of investigational product Arbidol (Umifenovir) in patients with a diagnosis of influenza and common cold. Furthermore, study of viral resistance in patients with seasonal influenza infection treated with Arbidol (Umifenovir) will be performed.
