Herpes labialis treatment with acyclovir 5 per cent ointment

Area of Science:

• Virology
• Dermatology
• Clinical Pharmacology

Background:

• Recurrent herpes labialis, commonly known as cold sores, is a frequent viral infection.
• Antiviral medications are often used for managing herpes simplex virus (HSV) outbreaks.

Purpose of the Study:

• To evaluate the efficacy of a 5% acyclovir ointment in treating recurrent herpes labialis.
• To compare the clinical healing effects of acyclovir ointment against a placebo.

Main Methods:

• A randomized, double-blind, placebo-controlled clinical trial was conducted.
• Eighty patients with culture-confirmed recurrent herpes labialis participated.
• Sixty patients completed two treatment episodes each.

Main Results:

• The 5% acyclovir ointment did not demonstrate superior clinical healing compared to the placebo.
• No significant difference in healing rates was observed between the acyclovir and placebo groups.
• No serious adverse events were reported in either treatment group.

Conclusions:

• Topical 5% acyclovir in a polyethylene glycol base is not clinically effective for treating recurrent herpes labialis.
• Further research may be needed to explore alternative topical antiviral treatments for HSV infections.
