Every country around the world has scientists working around the clock to find a COVID-19 vaccine. While the world waits in anticipation, the reality is, the creation of a vaccine may be months away. In fact, after many trials, it may not be ready for the world until next year.In the meantime, many doctors and specialists are trying to utilize already available drugs to help with coronavirus treatment. But are there any that are promising' Heres a closer look at four that might just be:ChloroquineIn the United States, the Food and Drug Administration, also referred to as the FDA, have approved chloroquine for coronavirus. This is for limited emergency use and it's not advertised as a cure for the virus.Chloroquine is normally used as a malaria drug. It's interesting to note that while this drug can be used in the US, the UK has not approved its use until there are more definitive trials carried out. Thus, they are waiting on more clear evidence before it's rolled out to the public.RemdesivirThe next drug that is being used is Remesivir. This was originally used to tackle Ebola. However, this was not effective against the disease. Despite this, researchers continued to work with the drug and found that it could inhibit SARS and MERS. This means that there is hope that this drug could help with coronavirus, as it's related to COVID-19.It's able to work by stopping the virus replicating itself. In other words, it may be able to stop the spread of the enzyme that the coronavirus uses. Currently, there are clinical trials with this drug happening in China and the US.FavilavirFavilavir, which is an antiviral drug, has been used in China since the outbreak. It was the first medication to be approved by the National Medical Products Administration of China for the pandemic. The studies on this drug are positive. It has helped to treat the disease with minimal side effects. However, it's likely that more clinical trials are necessary.Ritonavir and LopinavirThe combination of ritonavir and lopinavir is believed to help those suffering from coronavirus. These are normally antiviral drugs and they are often combined in order to create Kaletra. This is a drug used to fight HIV. They work together to inhibit enzymes. Indeed, it's believed that it may be able to do the same for coronavirus enzymes.It's important to note that a drug trial in China didn't work with COVID-19. However, it was a relatively small trial and only very ill patients were used. More testing is required for its effectiveness, as well as at varying stages of the disease.Overall, some of these drugs show potential. But there's simply not enough known about the coronavirus yet to say they will definitely be successful. More trials will be necessary and scientists are working hard to create a vaccine.In other industries, companies are working hard to find ways to help with lockdowns. Entrepreneurs, such as Tej Kohli, will also be important players during this time.Staff writer Click here to read full news..
