Well-known drug could yield new treatment for herpes viruses
Today, there is only one class of antiviral medicines against herpes viruses — a family of viruses that cause mononucleosis, herpes, and shingles, among other illnesses — meaning options for treating these infections are limited.

If viruses become resistant to these frontline treatments, a growing problem particularly in clinical settings, there are no alternative drugs to serve as backup.

In a search for new drugs to treat viral infections, scientists from the University of Utah School of Medicine found that a medicine routinely used to treat heart failure, spironolactone, has an unexpected ability to block infection by Epstein Barr virus (EBV), a herpes virus that causes mono and is associated with several human cancers.
