Sugar spheres are spherical excipients composed of sucrose and starch that are often produced using a layered sugar-coating structure. They can be coated with an active substance and sustained release additives to produce drug-filled sugar spheres. Using sugar spheres allows drug producers to outsource pelletization to specialists and focus on processing active pharmaceutical ingredients. The global sugar sphere market was valued at $142.4 million in 2019 and is projected to reach $229.9 million by 2027, growing at 6.5% annually.
