Phytosomes in Metabolic Disorders: Advancement and Innovative Approaches in Drug Delivery Systems

Metabolic disorders, including diabetes mellitus, obesity, dyslipidemia, and metabolic syndrome, represent a growing global health challenge due to their increasing prevalence, multifactorial etiology, and complex pathophysiological mechanisms. Conventional pharmacological interventions, while effective to some extent, are often associated with limitations, such as adverse effects, high costs, and the inability to provide multi-targeted therapeutic outcomes. In this context, phytochemicals derived from medicinal plants have emerged as attractive alternatives owing to their diverse biological activities, including antioxidant, anti-inflammatory, hypoglycemic, and metabolic regulatory effects. However, their clinical translation remains significantly restricted due to inherent drawbacks, such as poor aqueous solubility, limited gastrointestinal absorption, rapid metabolism, and low systemic bioavailability. To overcome these challenges, phytosome technology has gained increasing attention as a novel lipid-based drug delivery platform. In phytosomes, bioactive plant constituents form complexes with suitable phospholipids, thereby improving physicochemical stability, permeability, and targeted delivery. This approach not only enhances pharmacokinetic and pharmacodynamic properties but also ensures sustained therapeutic efficacy with improved patient compliance. Recent preclinical and clinical investigations have demonstrated the potential of phytosome- based formulations to modulate metabolic dysfunctions, regulate lipid and glucose homeostasis, and attenuate oxidative and inflammatory cascades associated with metabolic disorders. Moreover, emerging advancements, such as nanophytosomes, stimuli-responsive delivery systems, and synergistic phytosome-drug combinations, are further broadening the therapeutic scope. These innovative approaches hold promise for maximizing clinical outcomes, minimizing side effects, and offering cost-effective strategies in the management of chronic metabolic diseases. Collectively, phytosome technology represents a promising frontier in developing safe, effective, and translational plant-based therapeutics for addressing the global burden of metabolic disorders.
