Application

Penciclovir is a selective antiherpesvirus agent, particularly against herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV).

Biochem/physiol Actions

Penciclovir is converted to its active form, penciclovir triphosphate, by cellular kinases. It inhibits viral DNA polymerase by competing with deoxyguanosine triphosphate. It inhibits DNA synthesis of virus-infected cells. Penciclovir has in vitro activity against herpes simplex virus types 1 (HSV-1) and 2 (HSV-2). It does not inhibit DNA synthesis in non-infected cells. Mode of resistance is via qualitative changes in viral thymidine kinase or DNA polymerase.

Other Notes

Keep container tightly closed in a dry and well-ventilated place.

The objective of this investigation was to develop solid lipid nanoparticles (SLNs) of penciclovir and evaluate the potential of SLNs as the carrier of penciclovir for topical delivery. Penciclovir-loaded SLNs were prepared by a double (W/O/W) emulsion technique. The SLNs

Acyclovir, penciclovir, and their prodrugs have been widely used during the past two decades for the treatment of herpesvirus infections. In spite of the distribution of over 2.3 x 10(6) kg of these nucleoside analogues, the prevalence of acyclovir resistance

The metabolism and mode of action of penciclovir [9-(4-hydroxy-3-hydroxymethylbut-1-yl)guanine; BRL 39123] were studied and compared with those of acyclovir. In uninfected MRC-5 cells, low concentrations of the triphosphates of penciclovir and acyclovir were occasionally just detectable, the limit of detection

The purpose of this study was to investigate microemulsion-based hydrogel (MBH) as a topical delivery system for penciclovir. Topical delivery of penciclovir in the forms of microemulsion, MBH and the commercial cream was evaluated in vitro and in vivo. The
