Background: Wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. Recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. We investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (HSV-1) in cell culture.
Methods: In-vitro cytotoxicity study of empty niosomes (E-N), acyclovir loaded niosomes (ACV-N) and ACV as a free drug against HeLa cell line was performed by MTT assay and the viral titers was tested by TCID50 assay.
Results: The results indicated that a significant higher antiviral activity for acyclovir loaded nano-niosomes of about 3 times in comparison with free drug.
Conclusion: The results of this study revealed ACV-N have a higher antiviral activity compared with free drug; it could be a suitable carrier for delivery of acyclovir in the treatment of HSV-1 infections.

This study aimed to develop patches containing quercetin-loaded microcapsules and to evaluate their in vitro and in vivo safety and efficacy in preclinical surveys. A set of in vitro experiments evidenced the virucidal activity of quercetin against the HSV-1-KOS (sensitive to acyclovir) and HSV-1-AR (resistant to acyclovir) strains, with improved outcomes upon the first. The patches presented a homogeneous aspect, were easily handled, had a suitable bioadhesion, and possessed mechanical properties of soft and weak material, besides a pH compatible with human skin.

Acyclovir (ACV) is a potentially effective antiviral medication; however, it has a serious drawback, which is its poor solubility, bioavailability, and short half-life. The goal of this study is to improve its drawbacks through the synthesis of nanogels. In this study, the cross-linked hyaluronic acid-grafted poly(acrylamide--itaconic acid) nanogel is synthesized successfully through free radical polymerization and used as a safe pH-responsive carrier for ACV.

Background: Viral pneumonia, a pressing global health issue, necessitates innovative therapeutic approaches. Acyclovir, a potent ring-opening antiviral agent with broad-spectrum activity, faces water solubility, oral bioavailability, and drug resistance challenges. The aim of this study was to increase the efficacy of acyclovir through respiratory delivery by encapsulating it within albumin-modified lipid nanoparticles and formulate it as a spray.
