Famciclovir for the treatment of recurrent genital herpes: a clinical and pharmacological perspective
Bibliographic record
Abstract
Herpes simplex virus is one of the most common causes of genital ulcer disease worldwide. Herpes simplex virus-2 is the more common cause of genital herpes, a chronic infection that is characterised by periodic reactivation, with the capacity to produce recurrent symptomatic disease in the host (e.g., vesicular eruption), as well as intermittent asymptomatic shedding. Relapsing episodes may be physically and psychologically distressing. Shedding accounts for the majority of cases of transmission of genital herpes to sexual partners. Pregnant women who are shedding may transmit the virus at the time of delivery, with severe and potentially fatal consequences to the baby. Famciclovir, a synthetic acyclic guanine derivative, is the prodrug of penciclovir, which demonstrates in vitro antiviral activity against various types of herpes virus, including herpes simplex virus-2. Its pharmacokinetics allow for administration in a convenient dosing regimen compared with acyclovir, which may improve compliance. Clinical studies have demonstrated its efficacy in the episodic treatment of relapses, with the most recent report demonstrating its efficacy and tolerance as a single-day treatment. It is also efficacious and well tolerated for the suppression of frequently recurring episodes. These results have been demonstrated in various patient populations, including immunocompetent patients and those infected with HIV. Famciclovir is well tolerated, with an adverse events profile similar to placebo.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
