Abstract
The therapeutic effects of topically applied foscarnet sodium and acyclovir on cutaneous infections due to herpes simplexvirus type 1(HSV-1) were studied in guinea pigs. Foscarnet cream (3%) reduced both the cumulative vesicle score and the time for healing when HSV-1 strains C42 and 79 were tested. The application of foscarnet in cream form resulted in a dose-dependent reduction in skin virus titers and vesicle scores at concentrations ranging from 0.05% to 3%. Infections due to HSV-1 strain 79, but not those due to strain C42, were sensitive to treatment with 5% acyclovir in polyethylene glycolointment. Topical application of 3% acyclovirin dimethyl sulfoxide on infections due to HSV-1 strain C42 resulted in a reduction in the skin virus titers, lesion scores, and the time for healing. Acyclovir, in both polyethylene glycoland dimethyl sulfoxide, was consistently less active than foscarnet cream in these animal experiments.Keywords
