Only Rich Countries can Stockpile Drugs

A new study has said that stockpiling antiviral drugs as a weapon against pandemic flu saves lives but, when measured as a tool for averting economic damage, is an option only open to rich countries.

Researchers in Singapore compared benefits and disadvantages from stockpiling antivirals such as Tamiflu and Relenza in Brazil, Britain, China, Guatemala, India, Indonesia, New Zealand, Singapore, the United States and Zimbabwe.

Several drugs are either banned or withdrawn after introduction in the market.

They built a computer model based on the spread of a novel virus in Britain in the 1918, 1957, 1968 and 2009 pandemics.

It factored in expectations of fatalities and sickness as well as direct costs such as medical bills and indirect costs such as job absenteeism.

Stockpiling drugs saved lives in all countries, but its benefit, in economic terms, varied greatly.

About Chemotherapy Drugs
Chemotherapy drugs perform like ‘magic bullets’ to destroy cancer cells in the body.

For rich countries, it made sense to have a stockpile covering 15 percent of the population -- or, more realistically, 25-30 percent of the population, once inefficient distribution or waste are taken into account.

For the United States, according to the computer simulation, antiviral stockpiles saved the economy 27-55 billion dollars over 30 years.

Drugs Causing Sexual Problems
Sexual problems occur in males as well as in females. Drugs affecting the nervous and our endocrine or hormonal system may cause sexual dysfunction.

But for two-thirds of the world's countries, antiviral stockpiles are not cost-effective at current prices, as slender resources spent on the drugs could be used more productively in other health areas.

Among the countries studied, stockpiling would be cost-effective in China, India and Indonesia if antivirals fell below two dollars per course. But even at this price it would still be too dear for Zimbabwe, and by extension, other very poor countries, says the study.

The paper appears in a British publication, Journal of the Royal Society Interface.

Antiviral drugs are not a cure. Doctors say they can reduce the severity and duration of sickness provided they are administered at an early stage of infection.
