Tamiflu-the only drug to stop bird flu

Bird flu or avian flu has been a great concern to the human population worldwide. We had so many reports of tragic deaths due to bird flu and shortage of limited drugs like Tamiflu all across the globe. Today we have Governments and the entire World Health Organization, Red Cross, and other international health organizations wanting to spend millions to eradicate the killer disease from the living planet.

Treatment of bird flu

Tamiflu is the main drug for the treatment of bird flu. Tamiflu can lessen the effects of bird flu and speed up recovery. Tamiflu can also minimize the effects of bird flu to the point that a patient may survive the virus when, without Tamiflu, the attack would have been fatal. Tamiflu is the only drug that is this effective against the bird flu virus.
To be as effective as possible, a course of Tamiflu should be started within 24 hours of bird flu being diagnosed. This point is very important; delays in starting treatment lessen the effectiveness of the drug.

There are a few other influenza antiviral medications such as amantadine, rimantadine, and zanamivir, which have been approved by the U.S. Food and Drug Administration for the treatment and/or prevention of influenza including bird flu. Reports confirm that at times influenza virus strains can become resistant to one or more of these drugs, and thus the drugs may not always work. The bird flu influenza A (H5N1) viruses identified in human patients in Asia in 2004 and 2005 have been resistant to amantadine and rimantadine. Limited evidence suggests that some antiviral drugs, notably oseltamivir (commercially known as Tamiflu), can reduce the duration of viral replication and improve prospects of survival, provided they are administered within 48 hours following symptom onset.

Tamiflu dosage

In suspected cases, oseltamivir should be prescribed as soon as possible (ideally, within 48 hours following symptom onset) to maximize its therapeutic benefits. Currently recommended doses of oseltamivir for the treatment of influenza are contained in the product information at the manufacturer?s web site. The recommended dose of oseltamivir for the treatment of influenza, in adults and adolescents 13 years of age and older, is 150 mg per day, given as 75 mg twice a day for five days. Oseltamivir is not indicated for the treatment of children younger than one year of age. As the duration of viral replication may be prolonged in cases of H5N1 infection, clinicians should consider increasing the duration of treatment to seven to ten days in patients who are not showing a clinical response. In cases of severe infection with the H5N1 virus, clinicians may need to consider increasing the recommended daily dose or the duration of treatment, keeping in mind that doses above 300 mg per day are associated with increased side effects. In severely ill H5N1 patients or in H5N1 patients with severe gastrointestinal symptoms, drug absorption may be impaired.

Conclusion

Bird flu is not transmitted from one person to another. Individuals at risk are those are directly or indirectly exposed to sick chickens and other fowl. The government thereby advises travelers to countries affected with bird flu not to go to bird parks (aviaries), poultry farms or market where live poultry is sold. However, with the intervention of Tamiflu the infection toll of bird flu attacks have come down. The only reason of this is because Tamiflu treats flu at its source by attacking the virus that causes the flu, rather than simply masking symptoms.The author is an amateur writer focusing primarily on health related topics or on the health related research findings.
