    Area of Science:

    • Virology
    • Pharmacology
    • Immunology

    Background:

    • Antiviral therapy has advanced significantly, offering new hope for managing viral infections.
    • Vidarabine and acyclovir have shown efficacy against herpes simplex and varicella-zoster viruses.
    • Recombinant DNA technology has improved interferon production for clinical use.

    Purpose of the Study:

    • To review recent advancements in antiviral treatment options.
    • To highlight the efficacy of existing antiviral agents.
    • To discuss the potential of emerging antiviral drugs for complex viral infections.

    Main Methods:

    • Review of clinical trials and existing literature on antiviral therapies.
    • Discussion of drug mechanisms, toxicity, and selectivity.
    • Exploration of new drug development and their potential applications.

    Main Results:

    • Vidarabine is effective in neonatal herpes simplex and varicella-zoster infections in immunocompromised individuals.
    • Acyclovir demonstrates low host toxicity and high selectivity for herpes simplex and varicella-zoster viruses, proving effective in various patient groups.
    • Alpha interferon has shown promise in treating varicella-zoster infections and preventing herpes virus infections in high-risk populations.

    Conclusions:

    • Acyclovir represents a major breakthrough in antiviral therapy due to its safety and efficacy.
    • Newer interferon preparations require further confirmation for clinical efficacy.
    • Emerging antiviral drugs, including nucleoside analogues and novel interferons, hold promise for treating challenging viral infections like cytomegalovirus and hepatitis B.
