Pharmacology
Acyclovir is a synthetic deoxyguanosine analog and it is the prototype antiviral agent that is activated by viral thymidine kinase. The selective activity of acyclovir is due to its affinity for the thymidine kinase enzyme encoded by HSV and VZV.

side effects and Toxicity
Acyclovir may cause nephrotoxicity (crystallization of acyclovir within renal tubules, elevation of serum creatinine, transient), and neurotoxicity (coma, hallucinations, lethargy, seizures, tremors). Nephrotoxicity and neurotoxicity usually resolve after cessation of acyclovir therapy. However, there is no well-defined relationship between acyclovir concentrations in the blood and these adverse effects.
