🔬 Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionAcyclovir is only partially absorbed from the gastrointestinal tract; oral bioavailability is 15-30%.

DistributionWidely distributed; crosses the blood-brain barrier and placenta; appears in breast milk.

Protein Binding9-33%

MetabolismHepatic; minor metabolism by aldehyde oxidase and alcohol dehydrogenase.

Half-Life2.5-3.3 hours (normal renal function); up to 20 hours in end-stage renal disease.

ExcretionRenal (62-90% as unchanged drug) via glomerular filtration and tubular secretion.

Bioavailability15-30%

Onset of ActionNot well defined; antiviral effect begins after conversion to active triphosphate.

Peak Plasma Time1.5-2 hours

Duration of ActionApproximately 8 hours (dosing interval dependent on renal function).

How It Works

Acyclovir is converted to acyclovir monophosphate by viral thymidine kinase, then to triphosphate by cellular kinases, which inhibits viral DNA polymerase and incorporates into viral DNA, causing chain termination.

Mechanism Steps

1Acyclovir enters virus-infected cells.

2Viral thymidine kinase converts acyclovir to acyclovir monophosphate.

3Cellular kinases convert monophosphate to diphosphate and triphosphate.
