This study aimed to develop and evaluate hydrogels containing a cyclodextrin complex with clove essential oil and other free volatile oils with antimicrobial properties (tea tree and rosemary essential oils), focusing on their pharmaco-technical and rheological characteristics. The formulations varied in the Carbopol 940 (a hydrophilic polymer) and volatile oils' concentrations. Rheological analysis indicated that the gels displayed pseudoplastic behavior, with the flow index (n) values below 1, ensuring appropriate consistency and handling.

Article Synopsis
  • The research focuses on creating more effective drug delivery systems using magnetite nanoparticles (MNPs) to address microbial imbalance during cancer treatments.
  • MNPs were loaded with bee pollen extracts and the chemotherapy drug 5-fluorouracil (5-FU), and various analytical techniques were used to characterize their properties and performance.
  • The findings indicate that these MNPs enhance the antibacterial and antitumoral effects of 5-FU, with a prolonged release of bioactive compounds, suggesting they could be a promising option for treating colorectal cancer.

(1) Background: Oxidative stress plays a pivotal role in the pathogenesis of various diseases, including neurodegenerative disorders, cardiovascular diseases, cancer, and diabetes, highlighting the pressing need for effective antioxidant interventions. (2) Methods: In this study, we aimed to develop and characterise two novel antioxidant formulations, F3 and F4, as therapeutic interventions for oxidative stress-related conditions. (3) Results: The physicochemical characterisation, preformulation analysis, formulation, preparation of filling powders for capsules, capsule content evaluation, and antioxidant activity assessment of the two novel antioxidant formulations were assessed.
