title: Comparison of foscarnet cream, acyclovir cream, and acyclovir ointment in the topical treatment of experimental cutaneous herpes simplex virus type 1 infection.
abstract: Topical foscarnet (PFA) and acyclovir (ACV) were compared in the dorsal cutaneous guinea pig model of herpes simplex virus type 1 infection. The relative order of efficacy was PFA cream greater than ACV cream greater than ACV ointment. In vitro studies demonstrated that PFA and ACV formulated in cream vehicles penetrated through guinea pig skin 7- to 10-fold faster than did ACV in ointment.
