Acyclovir

A guanosine analog antiviral drug that acts as an antimetabolite. Acyclovir is used for the treatment of herpes simplex virus infections, varicella zoster (chickenpox) and herpes zoster (shingles). Acyclovir has also been investigated for the treatment of herpes labialis applied using an iontophoretic device. Currently approved drugs for the treatment of herpes labialis (cold sores) exhibit low levels of efficacy due to the limited ability of the drugs to penetrate the skin to the site where the herpes virus is replicating. Iontophoresis uses electric current to enhance the delivery of drugs through the skin.

Acyclovir (INN) or acyclovir (USAN, former BAN) 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. EC50 value of acyclovir against clinical herpes virus isolates was 1.3 μM (range: < 0.56 to 3.3 μM).

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.
