En el año 1962 se inició un proceso de investigaciones en fármacos antivirales en los laboratorios de Burroughs Wellcome & Company (actualmente Glaxo Smith Kline), que logró el descubrimiento del aciclovir en 1974 por Howard Schaeffer y Lilia Beauchamp.​ El descubrimiento del aciclovir fue considerado el comienzo de una nueva era en la terapia antiviral, ya que es extremadamente selectivo y posee un bajo nivel de citotoxicidad. Hitchings recibieron el Premio Nobel de Medicina en 1988 debido, en parte, al desarrollo de este compuesto.​ El aciclovir es un análogo de la guanina. Su estructura difiere de otros análogos de nucleósidos en que contiene sólo una parte de éste ya que el anillo glucídico está reemplazado por una cadena abierta. Se considera una prodroga, debido a que su forma original es inactiva, y sus metabolitos son las sustancias antivirales activas. Relacionado con el aciclovir, con mejor biodisponibilidad, está el famciclovir. El aciclovir se usa principalmente por vía oral mediante formulaciones en comprimidos y suspensión para el uso pediátrico. También se administra por vía tópica, en crema, e intravenoso en pacientes con infecciones graves por herpesvirus.​ Este efecto es en función de la dosis y no de la presentación.

Both are antiviral drugs and can be taken orally to shorten herpes symptoms or to prevent this infection from recurring in healthy individuals.
