Pharmacokinetics of Zovirax (Absorption, Distribution, Metabolism, Excretion)

Understanding the pharmacokinetics of Zovirax can provide valuable insights into how this antiviral medication behaves within the body. Let’s delve into the processes of absorption, distribution, metabolism, and excretion of Zovirax:


Zovirax is available in various formulations, including oral tablets, topical creams, and intravenous injections. The oral tablets are rapidly absorbed from the gastrointestinal tract, with peak plasma concentrations typically achieved within 1-2 hours after administration.

When applied topically, Zovirax cream can penetrate the skin and reach therapeutic levels in the affected area. This allows for direct action against the herpes virus at the site of infection.


Upon absorption, Zovirax is distributed widely throughout the body. It readily crosses cell membranes and can be found in various tissues, including the skin, kidneys, liver, and cerebrospinal fluid.

Acyclovir, the active ingredient in Zovirax, has relatively low protein binding, allowing for efficient distribution and availability in target tissues. Its ability to reach the central nervous system is particularly important in treating herpes infections that affect the brain and spinal cord.


The metabolism of Zovirax primarily occurs in the liver through a process called phosphorylation. In this process, acyclovir is converted into its active form, acyclovir triphosphate, which exerts antiviral effects against the herpes virus.

It is worth noting that acyclovir is predominantly eliminated from the body unchanged, indicating that it has a low potential for drug interactions mediated by metabolism. However, certain medications, such as probenecid, can competitively inhibit the renal excretion of acyclovir, leading to increased plasma concentrations and potential side effects.


The excretion of Zovirax occurs predominantly through the kidneys, both in its unchanged form and as various metabolites. Approximately 84% of the administered dose is eliminated within 24 hours, primarily through renal clearance.

It is crucial for patients to maintain hydration and adequate renal function while using Zovirax to ensure effective drug clearance. Adjustments in dosage may be necessary for individuals with impaired kidney function to prevent drug accumulation and toxicity.

Understanding the pharmacokinetic profile of Zovirax enhances our understanding of how this medication is absorbed, distributed, metabolized, and excreted from the body. Consultation with a healthcare professional is always advised for appropriate dosage recommendations and to address any concerns about medication interactions or individual differences in pharmacokinetics.

Pharmacokinetics of Zovirax (Absorption, Distribution, Metabolism, Excretion)

Zovirax, containing the active ingredient acyclovir, exhibits specific pharmacokinetic properties that contribute to its effectiveness in combating viral infections caused by the herpes virus.


When administered orally, Zovirax is rapidly absorbed from the gastrointestinal tract into the bloodstream. The bioavailability of acyclovir oral tablets ranges from 15% to 30%. The absorption is not significantly affected by food intake.


Upon absorption, acyclovir reaches systemic circulation and is widely distributed throughout the body. It readily crosses the blood-brain barrier and placenta, allowing it to reach viral targets in the central nervous system and in the developing fetus, respectively.

Acyclovir has a low binding affinity to plasma proteins. However, it does show some affinity for intracellular components of infected cells, allowing it to accumulate preferentially in herpes-infected tissues.


Acyclovir undergoes minimal metabolism in the body. The majority of the drug remains unchanged and is excreted in the urine. Only a small portion (less than 15%) is converted into an inactive metabolite, 9-carboxymethoxymethylguanine.


The primary route of elimination for acyclovir is renal excretion. It is predominantly excreted unchanged in the urine through glomerular filtration and active tubular secretion. The elimination half-life ranges from 2.5 to 3.3 hours in healthy individuals with normal kidney function. Dosage adjustments may be necessary in patients with impaired renal function to prevent the accumulation of acyclovir and potential toxicity.
