Advances in soft nanoparticle-based platforms for human and veterinary trichomoniasis therapy: A scoping review

This scoping review focuses on drug delivery systems based on soft materials designed for the administration of drugs with anti-Trichomonas vaginalis activity. It primarily examines their use in addressing human trichomoniasis, exploring their physicochemical characteristics, in vitro and in vivo evaluation and identifying existing challenges and gaps. Given the economic burden and the One Health approach, formulations developed aiming at treating animal infections - cattle and poultry - were also discussed. The review involved searching electronic databases, such as PubMed, Scopus, and Web of Science, to find studies published until May 2024; out of the 103 articles retrieved, 18 fulfilled the eligibility criteria. This study investigated soft-nanoparticle formulations, including polymericand lipid-based systems, and their incorporation into suitable formulations for topical application, including hydrogels and polymeric films. Additionally, the discussion covered toxicology and highlighted the knowledge gaps related to the potential use of these formulations in humans. Anti-trichomonas soft nano-based formulations emerge as promising candidates for treating gynecological and animal infections. In conclusion, further preclinical testing is necessary, as none of the formulations have progressed to human clinical trials and have only been evaluated in animal models.
