Laninamivir is an antiviral medication used to treat influenza (flu) in adults and children over the age of 2. It works by stopping the influenza virus from reproducing and spreading in the body. Laninamivir is taken as an inhalation powder, which is inhaled through the nose. It is usually taken twice daily for five days. Common side effects of Laninamivir include headache, runny nose, sore throat, and coughing.
Laninamivir is a medication used for the treatment and prevention of influenza A and B viruses, commonly known as the flu [1, 2]. It falls under the category of neuraminidase inhibitors [1]. Here's a breakdown of what Laninamivir does and how it works:
Mechanism of action:
Influenza viruses infect cells by attaching to their surface and then releasing their genetic material inside. Neuraminidase is an enzyme produced by the virus that helps new virus particles exit the infected cells and spread the infection. Laninamivir works by blocking the activity of neuraminidase. This essentially traps the new virus particles within the infected cells, preventing them from infecting other healthy cells and limiting the spread of the virus in the body [2, 3].
Key features of Laninamivir:
- Long-acting: Unlike some other influenza medications, Laninamivir is a long-acting drug. This means a single dose can provide protection or treatment for an extended period [2, 3].
- Administration: Laninamivir is typically administered via nasal inhalation [1].
- Approval status: Laninamivir is approved for use in Japan for both treatment and prevention of influenza. It's currently undergoing clinical trials in other countries [1].
