Zanamivir
Zanamivir
Zanamivir (pronounced: zah-NAH-mih-veer) is an antiviral drug used in the treatment and prevention of influenza caused by influenza A and B viruses.
Etymology
The name "Zanamivir" is derived from its chemical name: 5-acetamido-4-guanidino-2,3,4,5-tetrahydro-1,5-benzothiazepin-6-one. The "Zan" part of the name is a reference to the chemical structure of the drug, while "amivir" is a common suffix for antiviral drugs.
Usage
Zanamivir is used to treat influenza symptoms caused by the influenza virus in patients who have been symptomatic for no more than 2 days. It is also used for the prevention of influenza in patients who have a higher risk of developing complications from the flu.
Mechanism of Action
Zanamivir works by inhibiting the action of neuraminidase, an enzyme found on the surface of the influenza virus. By blocking this enzyme, the drug prevents the virus from spreading from infected cells to healthy cells.
Side Effects
Common side effects of Zanamivir include nausea, diarrhea, and sinusitis. In rare cases, it can cause more serious side effects such as bronchospasm or allergic reactions.
