Interaction of Acyclovir suspension with other medicines

Drug interactions are changes in the effect of one drug when used with another drug at the same time, which can strengthen or weaken their effect. Zovirax (Acyclovir) suspension, like any other drug, can interact with other medications, which is important to consider when compiling a comprehensive treatment regimen.

Antiviral agents

Valacyclovir: Given that valacyclovir is a prodrug of acyclovir, concomitant use with Zovirax may increase the concentration of acyclovir in the blood, potentially increasing the risk of side effects.

Other antiviral drugs: Concomitant use with other antiviral agents requires caution and monitoring, especially if they have similar mechanisms of action or are metabolized by the kidneys.

Antibiotics and antimicrobials

Antibiotics: Although no direct interactions between acyclovir and most antibiotics have been identified, it is important to inform your physician about all antibiotics taken, as some of them may affect renal function.

Drugs affecting renal function

Anti-inflammatory drugs (NSAIDs): Some NSAIDs can impair renal function, potentially increasing the risk of acyclovir accumulating in the body and developing toxic effects.

Diuretics: Especially loop diuretics may increase the indirect effect of Acyclovir on the kidneys, increasing the risk of nephrotoxicity.

HIV/AIDS medications

Zidovudine: Concurrent administration of acyclovir and zidovudine (AZT) in HIV-infected patients may result in increased drowsiness and fatigue, although the exact mechanism is unclear.

Immunosuppressors

Cyclosporine, tacrolimus and others: Their nephrotoxic effects may be increased when used concomitantly with acyclovir, which requires careful monitoring of renal function.

Antiepileptic agents

Concomitant use of acyclovir with antiepileptic drugs requires caution, as it may affect the levels of these drugs in the blood and enhance or weaken their effect.

How long does Zovirax (Acyclovir) suspension stay in the body, and how is it excreted?

Acyclovir is usually eliminated from the body by the kidneys within 24 hours after administration. The effectiveness and rate of excretion may vary depending on the kidney condition and the patient's overall health.

Acyclovir (Zovirax) cream/ointment

Acyclovir (Zovirax) cream or ointment, is an external form of an antiviral medication designed to treat the skin manifestations of infections caused by the herpes virus, such as herpes simplex (including herpes on the lips) and herpes zoster. These forms of the drug have a number of features that make them a convenient and effective means of combating viral infections of the skin.

Composition and form of release

The main active ingredient of Zovirax cream or ointment is Acyclovir - a synthetic analog of nucleoside, which inhibits viral DNA replication. Zovirax cream typically contains 5% acyclovir in a base suitable for external application. Zovirax ointment also contains 5% of the active ingredient, but may have a thicker and greasier texture compared to the cream.

Mechanism of action

Acyclovir in a cream or ointment, after application to the affected skin area, penetrates into the cells infected by the virus and is converted into the active form. In this active form, acyclovir is incorporated into the DNA of the virus, blocking its ability to reproduce further. This leads to the cessation of the spread of infection and promotes rapid healing of the affected areas of the skin.

Indications for use

Herpes simplex: Acyclovir cream or ointment is effective for treating herpes on the lips (labial herpes) and other shallow skin lesions caused by the herpes simplex virus.

Herpes zoster: Although herpes zoster usually requires systemic treatment, external application of acyclovir may help reduce localized symptoms.

Directions for use and dosage

Cream or ointment should be applied to the affected skin 4-5 times a day, usually for 5-10 days, until symptoms disappear completely. It is important to start treatment as early as possible, at the first signs of infection, to maximize the effectiveness of the medication.
