Abstract

Influenza viruses are an important cause of acute respiratory tract infections commonly found in populations of all age with regular pandemic in every year, leading to many global outbreaks in the past. It causes heavy burden in morbidities and deaths. Influenza outbreak occurs because the virus has continuously changed its genetic characteristics. Problem of resistance to anti-influenza drugs occurs quickly, in particular, that of M2 protein inhibiting anti-viral drugs such as amantadine and rimantadine which a very high rate of resistance is found. Researchers around the world therefore focus on the development of anti-influenza drugs. Main drug currently used is neuraminidase inhibitors causing the virus not being able to leave the host cell and spread. Currently available anti-influenza drugs in this group are zanamivir (relenza®), oseltamivir (tamiflu®), peramivir (rapivab®) and laninamivir (inavir®). Currently, laninamivir is licensed for distribution in Japan. However, the use of neuraminidase inhibiting anti-influenza drugs is still drug of first choice, leading to a higher utilization rate and an increasing risk of drug resistance in the future. There are also new drug groups interfering life cycle of influenza virus by inhibiting viral polymerase, leading to the termination of viral proliferation, such as baloxavir, marboxil (xofluza®) and favipiravir (avigan®). Favipiravir is currently licensed for distribution for treating influenza in Japan only. Development of new anti-influenza drugs is crucial in the treatment of the disease in order to reduce the losses caused by influenza outbreak in the future.
