Coronavirus
As a new strain of coronavirus (COVID-19) swept through the world in 2020, preparedness plans, masking policies and more public policy changed just as quickly. WVXU has covered the pandemic's impact on the Tri-State from the very beginning, when on March 3, 2020, Ohio Gov. Mike DeWine barred spectators from attending the Arnold Sports Festival in Columbus over concerns about the virus, even though Ohio had yet to confirm a single case of COVID-19.

UC Scientist Urges Caution Before Taking Remdesivir As COVID Treatment

Remdesivir, now known as Veklury, is administered by intravenous drip.

What seemed like a miracle drug for critically ill COVID patients may have some dangerous side effects according to a University of Cincinnati pharmaceutical scientist.

A new study's lead author Bingfang Yan and his graduate students found remdesivir, now known as Veklury, can permanently damage a key enzyme that helps break down many medications.

"So now based on our study and if you get remdesivir along with other medications that are metabolized by this particular enzyme (CES2) it may cause problems," Yan says.

CES2 is found in the intestine, liver and kidney.

"This enzyme normally breaks down and activates medicines in certain antivirals or inactivates other medicines such in certain anticoagulants,” says Yan, professor at the James L. Winkle College of Pharmacy. An antiviral is a drug against viruses and an anticoagulant is a drug that hinders the clotting of blood.

This breakdown increases the toxicity of many more medications such as with heart medicines and anticancer drugs, he says.

It can also cause other antiviral drugs, such as those used for HIV/AIDS and hepatitis C, to not work properly.

Yan says patients need CES2 to break down Veklury itself. He says the absence of the enzyme may be why the drug works on some COVID patients and others it does not.

The FDA has given Veklury emergency use authorization but Yan says the World Health Organization cautioned more study was needed.

Yan's research is published in Fundamental and Clinical Pharmacology.

He recommends patients talk to their doctor before receiving Veklury (remdesivir).
