ANTIFLU 75MG (OSELTAMIVIR)

What Is This Drug?

Antiflu 75mg is an anti-viral prescription medicine for the management and prevention of influenza A (including H1N1) and influenza B.[1] Its primary ingredient is oseltamivir phosphate, which restricts the activity of viral neuraminidase (explained later).

The U.S. Food and Drug Administration (FDA) advocates the oral administration of oseltamivir for treating influenza in adults and children who are two weeks or older. Oseltamivir is used to prevent influenza in one-year-old children or older.[2]

The medication exhibits maximum benefits when it is taken within 48 hours of manifestation of flu symptoms because its anti-viral effect starts to vanish after 48 hours of appearance of flu symptoms.[1]

Classification and Mechanism of Action

Oseltamivir is one of the anti-viral drugs that belong to the class of neuraminidase inhibitors.[3] It obstructs the working of viral neuraminidase enzymes, which are found on the surface of the virus.[1]

The neuraminidase enzymes have three crucial functions:[1]

  • To facilitate the entry of the virus into the uninfected human (host) cells
  • To release newly formed virus particles from infected host cells
  • To promote the further spread of the infectious virus in the body

Oseltamivir phosphate, an inactive compound, is converted into oseltamivir carboxylate, an active compound, inside the body. The active form restricts the activity of viral neuraminidase enzyme and prevents the release of influenza virus from infected human cells, thereby preventing its spread to other uninfected cells of the body.[3]

Looking After Your Drug

The storage temperature of this medication should be 20–25oC. This medication should be kept away from children’s reach, moisture, and excess heat.[4,5]
