The inhibitory effect of Acyclovir loaded nano-niosomes against herpes simplex virus type-1 in cell culture

  Background :Wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. Recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. We investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (HSV-1) in cell culture.   Methods : In-vitro...
