Pharmacological Action

Mechanism of Action:
Arbidol Hydrochloride is an antiviral agent primarily used to treat influenza and other respiratory viral infections. Its primary mechanisms of action include:

1. Inhibition of Viral Entry:

• Arbidol Hydrochloride stabilizes the hemagglutinin (HA) protein on the viral surface, preventing the fusion of the viral membrane with the host cell membrane. This inhibition of membrane fusion  blocks the entry of the virus into the host cell.

2. Immunomodulatory Effect:

• It has been shown to boost the immune response by  inducing interferon production and enhancing the activity of phagocytes,  a type of immune cell capable of engulfing and destroying pathogens.
