Pharmacological classification & ATC Classification:
J05AB01 - aciclovir; Belongs to the class of nucleosides and nucleotides excluding reverse transcriptase inhibitors. Used in the systemic treatment of viral infections.
Activity against HSV types I and II and varicella-zoster virus is due to intracellular conversion of aciclovir to the monophosphate by viral thymidine kinase with subsequent conversion to the diphosphate and active triphosphate by cellular enzymes. This active form inhibits viral DNA synthesis and replication by interfering with viral DNA polymerase enzyme and being incorporated into viral DNA.

Excretion: Via kidney by glomerular filtration and tubular secretion (14% as unchanged), via faeces (2%); elimination half-life: 2-3 hr (normal renal function), 19.5% (anuric patients), 5-7% (haemodialysis patients).
