    Area of Science:

    • Biotechnology
    • Nanomedicine
    • Pharmacology

    Background:

    • Liposomes are increasingly recognized for their potential in targeted drug delivery.
    • Their ability to accumulate in specific tissues like tumors or sites of inflammation is of significant interest.
    • This review focuses on recent in vivo applications with clinical relevance.

    Purpose of the Study:

    • To review recent in vivo studies on liposome drug delivery systems.
    • To discuss liposome preparation, drug entrapment, and controlled release mechanisms.
    • To evaluate the clinical potential and challenges of liposome-based therapies.

    Main Methods:

    • Review of recent in vivo research on liposome applications.
    • Discussion of factors influencing liposome stability and in vivo fate (composition, size, charge, administration route).
    • Analysis of liposome toxicity and biodistribution in preclinical models.

    Main Results:

    • Liposomes demonstrate efficacy in delivering antiparasitic drugs for malaria and leishmaniasis.
    • Surfactant-carrying liposomes show potential for treating respiratory distress syndrome.
    • In cancer models, liposome drug delivery systems have led to tumor regression and increased survival.

    Conclusions:

    • Liposomes offer a promising and versatile platform for targeted drug delivery with potential clinical applications.
    • Liposome stability, administration route, and patient factors are critical for successful in vivo therapy.
    • Despite challenges, liposomes hold significant promise for future therapeutic interventions across various diseases.
