Types segmentation delineates the structural diversity of multiparticulate systems, influencing manufacturing complexity and cost structure. Granules, typically 100 µm–1 mm in size, serve as the foundational unit for bulk dosing and are prevalent in oral and topical products. Pellets, ranging from 300 µm to 1 mm, provide uniform drug load and are essential for controlled‑release oral tablets. Microspheres, often polymeric and sub‑100 µm, enable parenteral and inhalation routes by offering tunable degradation rates and surface characteristics. Nanoparticles, below 1 µm, extend the taxonomy into targeted delivery, though they constitute a smaller market share due to higher production expenses. Coated beads, encompassing polymeric or lipid layers, enhance stability and modulate release kinetics across all applications. The relative contribution of each type reflects its suitability for specific therapeutic areas, with granules and pellets together representing the majority of market volume, while microspheres and nanoparticles drive niche, high‑value segments.
