چکیده
The influence of sodium lauryl sulfate (SLS) on the efficacies of topical gel formulations of foscarnet against herpes simplex virus type 1 (HSV-1) cutaneous infection has been evaluated in mice. A single application of the gel formulation containing 3% foscarnet given 24 h postinfection exerted only a modest effect on the development of herpetic skin lesions. Of prime interest, the addition of 5% SLS to this gel formulation markedly reduced the mean lesion score. The improved efficacy of the foscarnet formulation containing SLS could be attributed to an increased penetration of the antiviral agent into the epidermis. In vitro, SLS decreased in a concentration-dependent manner the infectivities of herpesviruses for Vero cells. SLS also inhibited the HSV-1 strain F-induced cytopathic effect. Combinations of foscarnet and SLS resulted in subsynergistic to subantagonistic effects, depending on the concentration used. Foscarnet in phosphate-buffered saline decreased in a dose-dependent manner the viability of cultured human skin fibroblasts. This toxic effect was markedly decreased when foscarnet was incorporated into the polymer matrix. The presence of SLS in the gel formulations did not alter the viabilities of these cells. The use of gel formulations containing foscarnet and SLS could represent an attractive approach to the treatment of herpetic mucocutaneous lesions, especially those caused by acyclovir-resistant strains.

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.

Effects of Sodium Valproate on the Replication of Herpes Simplex Virus Type 1: An in Vitro Study
Background: Sodium valproate, an anticonvulsant drug, is reported to stimulate Human Immunodeficiency Virus type 1 and Human cytomegalovirus replication. Since epileptic patients undergoing sodium valproate therapy may suffer from various virus infections, the effect of this drug on replication of viruses especially those affecting neuronal tissues such as Herpes simplex virus type 1 is worthy ...
