From Plant Extracts to Precision Therapy: The Role of Hydrogels in Modern Phytopharmaceuticals
Keywords:
Controlled release, Hydrogel drug delivery systems, Phytochemical bioavailability, Polymeric encapsulationAbstract
Abstract
Phytopharmaceuticals, encompassing a diverse array of bioactive plant-derived compounds, hold significant therapeutic potential but are frequently limited by poor solubility, instability, and low bioavailability. Hydrogels, three-dimensional polymeric networks with high water retention capacity, have emerged as a versatile delivery platform to overcome these challenges. This review comprehensively examines the role of hydrogels in enhancing the delivery and efficacy of phytopharmaceuticals. Natural and synthetic hydrogels offer unique physicochemical properties, including biocompatibility, biodegradability, and stimuli responsiveness, enabling controlled, sustained, and targeted release of phytochemicals. The encapsulation within hydrogels not only improves solubility and protects sensitive bioactives from degradation but also facilitates site-specific delivery and prolonged therapeutic action. Advanced hydrogel systems such as nanohydrogels and hybrid composites further enhance cellular uptake and multifunctionality, broadening their applications in phytomedicine. Despite promising outcomes, challenges remain regarding scale-up, reproducibility, and regulatory pathways. Future directions emphasize green synthesis approaches, smart responsive platforms, and personalized hydrogel formulations aligned with precision medicine. Overall, hydrogels represent a transformative technology in phytopharmaceutical research and development, providing innovative solutions to maximize the therapeutic potential of plant-derived drugs.
