Aralen (Chloroquine), which has long been used to treat malaria, has been shown to be effective in treating Covid-19 coronavirus. On February 25, the head of University Hospital Institute Méditerranée Infection Didier Raoult reported this issue.
French scientist cites in vitro experiments and a clinical study conducted in China. A number of doctors point to the need for additional research.
Didier Rault noted that Aralen has already shown effectiveness in controlling the new coronavirus during in vitro experiments. The drug effectiveness was confirmed by a clinical study on individuals in China.
The treatment of Covid-19 is probably the simplest and cheapest among all viral infections. Aralen has been used for the treatment of malaria for over 70 years.
On February 19, BioScience Trends published an article reporting the results of using chloroquine for treating Covid-19 virus pneumonia in more than 100 patients in 10 Chinese hospitals (including Wuhan). The study was conducted by 3 Chinese scientists from Qingdao.
A Chinese study showed that antimalarial medicine showed comparative effectiveness to restrain the development of pneumonia, improve lung condition and reduce the disease duration. The authors of the article indicate that it is enough to take daily 500 mg of Aralen for 10 days to cure coronavirus.
Didier Raoult of the Marseille Institute believes that at the moment, doctors need to concentrate on these trials since the vaccine can still not be discovered earlier than after a few months.
French Health Minister Olivier Veran said he discussed this several times with Didier Rault. According to, the Directorate-General of Health is now analyzing this information.
International medical workers are looking for a cure for the new coronavirus since the epidemic outbreak. There are test drugs that have shown effectiveness for the treatment of viruses close to Covid-19.
It’s too early to say that Aralen (chloroquine) can be used to treat patients with coronavirus. According to this opinion, doctors cannot “improvise” without having enough evidence on drug effectiveness.
