"When you go with a brand new drug, you don't know what's going to happen".
The drug is chloroquine, a widely prescribed anti-malaria pill that was first approved in the United States in 1949.
Early trials of the drug have suggested that chloroquine could work against coronavirus.
Chloroquine offers a simple, affordable and scalable treatment option to coronavirus patients--standing out against next-generation therapeutics and other expensive treatments used to curb the virus. "Safety data and data from high-quality clinical trials are urgently needed".
Though, yet to be approved by the United States Food and Drug Administration (FDA) - the U.S. body responsible for regulating health and human services, Rigano, however, proved further authenticity of the discovery by sharing publicly the peer-reviewed study earlier released by Didier Raoult, also a Medical Doctor.
Azithromycin, an antibiotic, also helped fight lung infections on coronavirus patients when combined with the anti-malaria drug.
Meanwhile, on Wednesday, the World Health Organisation (WHO) reportedly listed chloroquine among four drugs identified for a multinational clinical trial as part of efforts to find a cure to the pandemic.
According to China's National Health Commission, the drug was effective against preventing organ failure and an overreaction of the immune system on coronavirus patients.
Tedros Adhanom Ghebreyesus, the WHO Director-General said the four drugs or a combination of an existing drug used to cure other ailments would be tested while 10 nations already signified interest in the clinical trial.
There are currently no vaccines or treatments for the highly-contagious COVID-19 respiratory illness, so patients can only receive supportive care for now.
Another research company, Sanofi and Regeneron, is planning on launching a clinical trial in NY to see if their drug Kevzara will produce positive results.
The FDA, CDC, and various European agencies are cooperating with AbbVIe, the creator of HIV drugs Kaletra/Aluvia, to determine whether the drug could be used to treat COVID-19 patients.
Other drugs include remdesivir which is an antiviral type of drug that is now being developed biotech giant, Gilead Sciences.
"We are trying to leverage the science to see if we can do something in addition to minimizing contacts", said Dr. Jakub Tolar, dean of the University of Minnesota Medical School and vice president for clinical affairs. However, the drug has drastic side effects such as damage to the eyes, headaches, dizziness, vomiting, and diarrhea.
Doctors in Australia, France and elsewhere say they've had success treating coronavirus patients with hydroxychloroquine, a readily available drug that treats malaria, lupus and arthritis.
