The antiviral drug, called Favipiravir or Avigan, showed positive outcomes in clinical trials involving individuals in Wuhan and Shenzhen, said Zhang Xinmin, of China's science and technology ministry, The Guardian reported.

Developed by Fujifilm Toyama Chemical, the antiviral drug is being manufactured by Zhejiang Hisun Pharmaceutical for treating influenza viruses. Last month, the drug reportedly received approval as an experimental treatment for COVID infections, Pharmaceutical Technology reported. Patients in Shenzhen who had tested positive for COVID and who were given the drug got a negative virus test back four days later, as a median half showed a negative test earlier and half later than four days.

That was compared with a negative test about 11 days later, as a median, for patients not on the drug, according to news reports. In the Wuhan trial, the drug also seemed to shorten the duration of a patient's fever from an average of 4. The drug stops some viruses from replicating by crippling the enzyme a substance that gets chemical reactions going called RNA polymerase, which builds RNA. Without that enzyme intact, the virus can't duplicate its genetic material efficiently once inside a host cell, according to an article describing the drug that was published in in the journal Proceedings of the Japan Academy, Ser.

Doctors are using the same drug in Japan to treat coronavirus patients with mild to moderate symptoms, The Guardian reported.

However, antiviral drugs developed to treat other illnesses are being tested for their use in treating the coronavirus.

For instance, Remdesivir was developed to treat Ebola but it has shown promise in treating monkeys infected with another coronavirus, the Middle East respiratory syndrome MERS ; that drug is currently being tested in China and the U. In addition, clinical trials have begun to test an experimental coronavirus vaccine in humans.

These drugs work against influenza type A viruses, but not influenza type B viruses. They are thought to inhibit the activity of an influenza A viral protein, which prevents the virus from replicating after it enters a cell. Zanamivir an inhaled powder and oseltamivir oral drug are medications known as neuraminidase inhibitors. These are a newer type of medication that works by blocking the active site of the influenza viral enzyme neuraminidase, which is found in both influenza A and influenza B viruses.

This enzyme normally breaks the bonds that hold new virus particles to the outside of an infected cell. This frees new viruses to infect other cells and spread infection. Neuraminidase inhibitors' ability to block this enzyme's activity prevents new virus particles from being released. This limits the spread of infection. All four medications are known to be effective in modestly reducing the duration of flu symptoms by about one day when taken within two days after a person has been infected.

They may also make infected people less contagious. Early indications are that oseltamivir may be effective in treating bird flu, but more study is needed before this can be declared to be the case.
