Abstract
Aim: The study aimed to enhance phloretin's oral absorption and systemic availability through nanoencapsulation within biodegradable polymers, improving its anti-oxidant and cardioprotective potential.
Methods: Phloretin-loaded polymeric nanocomposites were prepared using ionic gelation and optimised for yield, encapsulation, loading, particle size, PdI and zeta potential. The formulation was characterised by FTIR, XRD, FESEM and MS. In-vitro drug release, stability, pharmacokinetics, biodistribution, anti-oxidant capacity, haemolysis and both in-vitro and in-vivo assessments were conducted in an ischaemia-induced rat model.
Results: The average particle size, zeta potential, encapsulation and drug loading of the optimised nanoparticles were 105.8 ± 1.92 nm, -41.5 ± 1.10 mV, 92.36 ± 0.01% and 18.47 ± 0.38%, respectively. Nano-phloretin enhanced oral bioavailability, anti-oxidant capacity. In-vivo, it reduced myocardial infarct size by ∼46% versus ∼13% for free phloretin, showing significant cardiomyocyte protection and ROS suppression.
Conclusion: The study demonstrates polymer-based nanoparticles as effective oral drug delivery systems capable of enhancing both systemic bioavailability and therapeutic efficacy of the encapsulated drug.
期刊介绍:
The Journal of Microencapsulation is a well-established, peer-reviewed journal dedicated to the publication of original research findings related to the preparation, properties and uses of individually encapsulated novel small particles, as well as significant improvements to tried-and-tested techniques relevant to micro and nano particles and their use in a wide variety of industrial, engineering, pharmaceutical, biotechnology and research applications. Its scope extends beyond conventional microcapsules to all other small particulate systems such as self assembling structures that involve preparative manipulation.
The journal covers:
Chemistry of encapsulation materials
Physics of release through the capsule wall and/or desorption from carrier
Techniques of preparation, content and storage
Many uses to which microcapsules are put.
