This defect is associated with exposure of tablet cores to coating process conditions rather than the coating itself.

• A. Logo Infilling
• B. Rough Coating
• C. Delayed Dissolution for IR Products
• D. Tablet Twinning

Answer: (C)

Delayed dissolution for IR products is the defect that shows up when the tablet core is altered by the coating process conditions themselves, not by the coating layer’s quality. During film-coating, exposure to heat, solvents, and moisture can change the core’s internal structure or disintegration behavior. In immediate-release products, this means the core dissolves more slowly than intended, even if the coating looks fine. Other defects—like a logo becoming filled, a rough coating, or two tablets sticking together—are tied to surface coating quality or handling, not to changes induced in the core by the coating process.
