A drug used to treat parasitic infections killed the new coronavirus in less than 48 hours in a lab setting, according to Australian researchers. Experts say more testing is needed to know if it works well in people and safe to use. More information:
The drug is"safe at relatively high doses, widely available, and relatively cheap, too," Jans says. The next step is more research to find the best dose for fighting COVID-19. Then researchers can begin testing in people, he says."It is important to stress that no one should try to self-medicate with versions of ivermectin that are for veterinary purposes or head lice." The only safe way to get ivermectin is by prescription from a doctor, he says.
The important caveat, says Weatherhead, who reviewed the study but was not involved in the research, is that it was done in a lab. But"at this point, any lead we have should be investigated," she says."What we really need to know is, could you translate that concentration [of the drug used in the lab study] into human studies and have it be safe?"
"The results are promising," agrees Katherine Seley-Radtke, PhD, a professor of chemistry and biochemistry at the University of Maryland, Baltimore County. She holds patents on compounds that are also being studied for COVID-19. "Ivermectin," she says,"has shown effectiveness against other viruses, despite being an anti-parasitic drug." The drug is worthy of further study, Seley-Radtke says, but she calls the findings"very preliminary."
