Swine influenza (H1N1) viruses contain a unique combination of gene segments that have not been reported previously among swine or human influenza viruses in the US or elsewhere. The H1N1 viruses are resistant to amantadine and rimantadine but not to oseltamivir or zanamivir.

Bronchospasm and decline in lung function have been reported in some patients receiving relenza. Many but not all of these patients had underlying airways disease such as asthma or chronic obstructive pulmonary disease. Because of the risk of serious adverse events and because efficacy has not been demonstrated in this population, /zanamivir/ is not generally recommend for treatment of patients with underlying airways disease. Some patients with serious adverse events during treatment with /zanamivir/ have had fatal outcomes, although causality was difficult to assess. /Zanamivir/ should be discontinued in any patient who develops bronchospasm or decline in respratory function; immediate treatment and hospitalization may be required. Some patients without prior pulmonary disease may also have respiratory abnormalities from acute respiratory infection that could resemble adverse drug reactions or increase patient vulnerability to adverse drug reactions.

Adverse effects occurring in 1-3% or more of adults and children 12 years of age or older include diarrhea; nausea; vomiting; nasal signs and symptoms; bronchitis; sinusitis; cough; ear, nose, and throat infections; headache; and dizziness. No adverse effect occurred at an incidence greater than 3%. Adverse effects occurring in up to 5% of children 5-12 years of age include ear, nose, and throat infections; vomiting; nausea; and diarrhea. Some adverse effects may be secondary to lactose vehicle inhalation. Bronchospasm and allergic-like reactions, including oropharyngeal edema and serious rash, have been reported. Unlike amantadine and rimantadine, neuraminidase inhibitors like zanamivir do not appear to adversely affect the CNS.

For the prevention and treatment of influenza A and B.
FDA Label
Dectova is indicated for the treatment of complicated and potentially life-threatening influenza A or B virus infection in adult and paediatric patients (aged 6 months) when:
- The patients influenza virus is known or suspected to be resistant to anti-influenza medicinal products other than zanamivir, and/or
- Other anti-viral medicinal products for treatment of influenza, including inhaled zanamivir, are not suitable for the individual patient.
Dectova should be used in accordance with official guidance.
Prevention of influenza, Treatment of influenza
Zanamivir, an antiviral agent, is a neuraminidase inhibitor indicated for treatment of uncomplicated acute illness due to influenza A and B virus in adults and pediatric patients 7 years and older who have been symptomatic for no more than 2 days. Zanamivir has also been shown to significantly inhibit the human sialidases NEU3 and NEU2 in the micromolar range (Ki 3.7 +/-0.48 and 12.9+/-0.07 microM, respectively), which could account for some of the rare side effects of zanamivir.
Antiviral Agents
Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly. (See all compounds classified as Antiviral Agents.)
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)

Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 1526
The proposed mechanism of action of zanamivir is via inhibition of influenza virus neuraminidase with the possibility of alteration of virus particle aggregation and release. By binding and inhibiting the neuraminidase protein, the drug renders the influenza virus unable to escape its host cell and infect others.
Zanamivir is a potent selective competitive inhibitor of the influenza virus neuraminidase, an enzyme essential for viral replication. Neuraminidase cleaves terminal sialic acid residues from glycoconjugates to enable the release of virus from infected cells, prevent the formation of viral aggragates after release from host cells, and possibly decrease viral inactivation by respiratory mucous.
