Epstein Barr Virus

Drugs against EBV are mostly ineffective in humans. – Pharmacology & Pharmacy (1)

There are no FDA approved antiviral drugs that target the Epstein Barr Virus (EBV). Nevertheless, some drugs have shown promising activity in the lab according to a study published in 2005 in the Journal of Antimicrobial Chemotherapy (2).

The CDC says that EBV is a major health problem. “Epstein-Barr virus, frequently referred to as EBV, is a member of the herpes virus family and one of the most common human viruses. The virus occurs worldwide, and most people become infected with EBV sometime during their lives (3).” In addition, EBV causes “infectious mononucleosis 35% to 50% of the time. Symptoms of infectious mononucleosis (IM) are fever, sore throat, and swollen lymph glands. Sometimes, a swollen spleen or liver involvement may develop (3).”

Attempts to use broad range antiviral drugs such as acyclovir showed limited effectiveness.

Study authors wrote that, “Despite the availability of many antiviral drugs starting with acyclovir that are potent inhibitors of EBV replication in cell culture, clinical trials of aciclovir (another name for acyclovir) for the treatment of patients with IM have failed to detect benefit (2).”

Thus, “Despite their potency in vitro (in cell culture), these drugs have limited use in vivo (in patients) for treatment of acute primary EBV infection as well as EBV-associated malignancies… (2).”

The authors of the study made an important statement.

natural drugs

Development of novel antiviral drugs that target non-replicative viral proteins, are among the more promising approaches that might lead to effective treatment of EBV-related diseases (2).”

In other words, the authors said that antiviral products, which target the latent EBV, may be the most effective treatments against EBV related diseases.

The bottom line?

Time and again, we find that new research supports our understanding that helping the immune system target the latent virus is the best way to prevent disease.
