Pharmacodynamics and pharmacokinetics
After oral administration, the active substance of the drug is converted to penciclovir, which has an impact on the cytomegalovirus, as well as the Epstein-Barr virus and human herpes viruses. It falls into the infected areas of the body, where it turns into a monophosphate, turning into a triphosphate. Being in infected cells for more than 12 hours, it prevents replication of viral DNA. Its content in cells, where there is no virus, is minimal, so they do not affect triphosphate.
Potenzieller acts against acyclovir resistant strains of Herpes simplex with changed DNA polymerase.
The drug reduces the manifestation and duration of postherpetic neuralgia in people with herpes zoster.
Its bioavailability is 77%. The maximum drug concentration is achieved in approximately 45 minutes. Penciclovir is characterized by the degree of connection with plasma proteins by less than 20%. Half-life time of plasma up to 2 hours. The active substance of the drug is excreted mainly in the urine.
