Common tablet, capsule, and coating defects with root causes and practical troubleshooting in pharmaceutical manufacturing.
Introduction Double Impression in Tablets is a common visual defect observed during tablet manufacturing. This defect appears when the logo, monogram, score line, or embossed marking on a tablet is duplicated, resulting in a blurred or double-printed appearance. Although the defect may not directly affect the tablet’s potency, it significantly impacts product appearance, brand identification, […]
Introduction Tablet appearance is one of the most important quality attributes in pharmaceutical manufacturing. Even when a tablet meets all chemical and physical specifications, visual defects can lead to product rejection by customers and regulatory concerns. Among the common pharmaceutical tablet defects, Tablet Mottling Defect is frequently observed in both uncoated and coated tablets. This
Introduction Cracking in Tablets is a common quality defect observed during pharmaceutical tablet manufacturing. It appears as fine cracks or complete splits on the tablet surface, often reducing product quality, stability, and patient acceptance. This defect can occur during compression, coating, handling, packaging, or transportation. This article explains the causes of tablet cracking, identification methods,
Introduction Tablet Chipping Defect is one of the most common tablet manufacturing defects observed during tablet compression and handling. It occurs when small pieces break away from the edges of a tablet, resulting in an uneven appearance and reduced product quality. Chipping not only affects the visual appearance of tablets but may also indicate underlying
Introduction Tablet Picking and Sticking are among the most common tablet compression defects encountered during pharmaceutical manufacturing. These defects can affect tablet appearance, reduce product quality, increase rejection rates, and cause production delays. During the tablet compression process, powder particles may adhere to the punch face or die wall, leading to defects on the tablet
Introduction Lamination Defect in Tablets is one of the most common tablet compression defects encountered in pharmaceutical manufacturing. It occurs when a tablet separates into two or more distinct horizontal layers either during compression, ejection, packaging, transportation, or storage. Tablet lamination not only affects the physical appearance of the tablet but can also impact product
Introduction Tablet compression is one of the most critical stages in pharmaceutical manufacturing. During compression, various tablet defects can occur if formulation, granulation, equipment, or process parameters are not properly controlled. One of the most common tablet compression defects is the Capping Defect in Tablets. Capping can lead to product rejection, increased manufacturing costs, production
Introduction Tablets are the most widely used dosage form in the pharmaceutical industry due to their convenience, stability, accurate dosing, and cost-effectiveness. However, maintaining consistent tablet quality can be challenging during manufacturing. Various problems may arise during granulation, blending, compression, coating, or packaging stages, leading to tablet defects. Understanding the Common Tablet Defects in Pharmaceutical
Tablet compression is one of the most critical stages in solid oral manufacturing. Even when granulation and blending are perfect, small mistakes during compression can lead to major defects like capping, lamination, sticking, picking, or weight variation. These defects not only affect product quality but also create regulatory risks during audits. In real manufacturing environments,
Tablet manufacturing defects are one of the most common challenges in pharmaceutical production. Even when granulation and compression are properly executed, small parameter variations can lead to serious product quality issues. In this guide, we will understand: This article will help production operators, QA professionals, and students clearly understand how to control defects in real
