Curcumin-resveratrol nano-formulation counteracting hyperammonemia in rats

Recent advances in encapsulation of resveratrol for enhanced delivery

Due to its numerous biological activities, such as antioxidant, anti-inflammatory, antitumor, anti-atherosclerosis, anti-aging, anti-osteoporosis, anti-obesity, estrogenic, neuroprotective and cardioprotective effects, resveratrol has attracted a lot of attention in the food and pharmaceutical industries as a promising bioactive. However, low solubility in aqueous media, limited bioavailability, and low stability of resveratrol in hostile environments limit its applications. The necessity for a summary of recent developments is highlighted by the growing body of research on resveratrol encapsulation as a means of overcoming the mentioned application constraints. This review highlights the present developments in resveratrol delivery techniques, including spray drying, liposomes, emulsions, and nanoencapsulation. Bioaccessibility, bioavailability, stability, and release of resveratrol from encapsulating matrices are discussed. Future research should focus on encapsulation approaches with high loading capacity, targeted delivery, and controlled release. In light of the growing interest in resveratrol and the increasing complexity of resveratrol-based formulations, review of current encapsulation methods is crucial to address existing limitations and pave the way for the development of next-generation delivery systems. This review discusses how the delivery systems with different structures and release mechanisms can unlock the full potential and benefits of resveratrol by enhancing its bioavailability and stability.

Nanocarrier-mediated curcumin delivery: An adjuvant strategy for CNS disease treatment

Neurological disorders are a major global challenge, which counts for a substantial slice of disease burden around the globe. In these, the challenging landscape of central nervous system (CNS) diseases, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and neuro-AIDS, demands innovative and novel therapeutic approaches. Curcumin, a versatile natural compound with antioxidant and anti-inflammatory properties, shows great potential as a CNS adjuvant therapy. However, its limited bioavailability and suboptimal permeability to the blood-brain barrier (BBB) hamper the therapeutic efficacy of curcumin. This review explores how nanocarrier facilitates curcumin delivery, which has shown therapeutic efficacy for various non-CNS diseases, for example, cancers, and can also revolutionize the treatment outcomes in patients with CNS diseases. Toward this, intranasal administration of curcumin as a non-invasive CNS drug delivery route can also aid its therapeutic outcomes as an adjuvant therapy for CNS diseases. Intranasal delivery of nanocarriers with curcumin improves the bioavailability of curcumin and its BBB permeability, which is instrumental in promoting its therapeutic potential. Furthermore, curcumin's inhibitory effect on efflux transporters will help to enhance the BBB and cellular permeability of various CNS drugs. The therapeutic potential of curcumin as an adjuvant has the potential to yield synergistic effects with CNS drugs and will help to reduce CNS drug doses and improve their safety profile. Taken together, this approach holds a promise for reshaping CNS disease management by maximizing curcumin's and other drugs' therapeutic benefits.
