present invention the amount of acv in the mixture will range from about 1 to 10 by weight of the total mixture in another embodiment of the composition of the present invention the amount of acv in the mixture will range from about 2 to 5 by weight of the total mixture further an embodiment of the composition of the present invention will contain about 3 75 acv by weight of the total mixture penciclovir u201c pcv u201d is also known by the official iupac name as 2 amino 9 4 hydroxy 3 hydroxymethyl butyl 6 9 dihydro 3 h purin 6 one pcv has a molecular formula of c 10 h 15 n 5 o 3 and is a synthetic acyclic guanine derivative with a structure as follows similar to acv pcv is believed to be phosphorylated by thymidine kinase to a monophosphate form which in turn is then converted to an active state penciclovir triphosphate by cellular kinases in vitro hsv dna synthesis and replication are inhibited by penciclovir triphosphates inhibiting hsv polymerase competitively with deoxyguanosine triphosphate because pcv is phosphorylated into its active form only by the viral specific thymidine kinase the active triphosphate state is confined to only the virus infected cells pcv administration may include oral in tablets topical intravenous and ophthalmic commonly pcv is most widely commercially available in a 1 topical cream under the name denavir u00ae the topical cream.
