A DRUG that treats a rare enzyme disorder could help treat the herpes virus that causes cold sores.
When the drug – called phenylbutyrate – was used along with acyclovir (a treatment for herpes), the combination cleared the virus, which also causes genital herpes, faster than when either was given alone, a study by the University of Illinois, U.S., found.
The researchers say that as the drug is licensed, it could be available for treating herpes faster.
