What is the duration of oral acyclovir’s effect on herpes infections?

The duration of oral acyclovir's effect on herpes infections typically falls within the range of 10-15 hours. This timeframe reflects the drug's pharmacokinetics, including its absorption, distribution, metabolism, and excretion. Acyclovir is administered for the management of herpes simplex virus infections, and its effectiveness is particularly tied to maintaining therapeutic levels in the bloodstream.

When considering the choice of 10-15 hours, it aligns with clinical findings that show acyclovir's antiviral activity is sustained for this duration, allowing for effective suppression of viral replication during treatment. The other options suggest shorter or longer durations, which would not accurately reflect the time frame in which acyclovir remains effective after a single oral dose. Understanding this aspect is crucial for ensuring optimal dosing regimens that can help manage herpes infections effectively.
