Tromantadine hydrochloride, an Amantadine derivative with antiherpetic activity, inhibits herpes simplex virus type 1 (HSV-1) and HSV-2 replication In Vitro Treatment of the cells with 10 to 50μg of Tromantadine reduces HSV-induced cytopathic effect. Treatment with 100 to 500μg of Tromantadine inhibits herpes simplex virus-induced cytopathic effect and reduces virus production. Complete inhibition of virus production is observed with treatments of 500μg to 1 mg. The antiherpetic activity of Tromantadine is dependent upon the viral inoculum size and the time of addition of the compound with respect to infection. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:HSV-1 HSV-2
