Pediatric drug delivery presents unique challenges due to physiological and pharmacological differences across age groups, requiring specialized formulation approaches beyond simple dose adjustments of adult medications. This review synthesizes recent advances in polysaccharide-based pediatric drug delivery and highlights novel findings that may accelerate clinical translation. It summarizes how chitosan, alginate, hyaluronic acid, dextran, modified starches, and other polysaccharides are engineered into nanoparticles, hydrogels, films, and orodispersible/mini-tablet formulations to improve stability, bioavailability, taste masking, and controlled release across neonates to adolescents. These systems can accommodate developmental variations in absorption, distribution, metabolism, and excretion processes across pediatric subpopulations, with particular emphasis on oral and alternative administration routes. Evidence supporting unexpectedly high acceptability of mini-tablets, successful integration of modified polysaccharides in 3D-printed personalized low-dose therapies, and the emergence of blood–brain barrier-penetrating and RGD-functionalized polysaccharide nanocarriers for pediatric oncology are emphasized as novel, clinically relevant trends. This review also addresses regulatory considerations, safety profiles, and future perspectives. By integrating developmental insights with innovative formulation strategies, polysaccharide polymers offer promising solutions to improve medication adherence, safety, and efficacy across the pediatric age spectrum.
