ABSTRACT
Silver sulfathiazole shows strong antibacterial activity and good tolerance after topical application. The aim of the study was to determine the antiviral activity of silver sulfathiazole in tissue culture after incubation of drug and virus. The antiviral activity was measured after various periods of exposure and at different drug concentrations. The results obtained indicate the activity of silver sulfathiazole against Herpesvirus type 1 and type 2. This drug suppresses or completely inactivates the infectivity of virus. The antiviral effect is directly related to concentration of the drug and duration of exposure. At concentration of 10 micrograms/ml it has the highest activity after 30 minutes of exposure, however at a concentration of 20 micrograms/ml it induces a similar effect after 10 minutes. Silver sulfathiazole had antiviral activity similar to that of silver nitrate, while sulfathiazole alone was ineffective.
