🌀 Blending and Granulation: Key Manufacturing Steps

Blending is crucial for creating a homogeneous mixture of active ingredients and excipients. Different blenders, such as V-cone, double cone, and octagonal, are used depending on batch size. Granulation, the most critical step, involves turning powders into granules to enhance flow and aid compression. Wet granulation uses liquid, while dry granulation does not. Equipment like rapid mixer granulators and binders are vital to controlling the size, shape, and drug release properties of the granules.

🌬 Drying Methods in Tablet Manufacturing

Granules are dried to remove excess moisture using methods like tray drying and fluid bed drying (FBD). FBD is preferred in pharmaceuticals, where hot air passes through a perforated bowl, drying the material. Special FBD bags increase surface area, helping dry material more effectively while minimizing loss. Moisture content is manually checked during the process to ensure the required level is achieved before proceeding to compression.

💪 Compression: Forming Tablets with Precision

The compression stage transforms granules into tablets using tablet press machines, which apply high pressure to form tablets of specific shapes and sizes. Proper compression affects the physical properties of the tablets, including hardness, thickness, and dissolution rates. Compression must be precise to ensure tablets release the active ingredients as intended, making this a critical step in the manufacturing process.

🎨 Coating and Polishing: Enhancing Tablet Appearance and Function

The coating stage adds a smooth outer layer to tablets, improving appearance, stability, and masking unpleasant tastes. Methods like dipping or spraying apply the coating, and the type of solution determines additional benefits like delayed dissolution in acidic environments (e.g., enteric coatings). After coating, tablets are polished to remove sharp edges and achieve a shiny finish. Branding with food-grade inks can also be added, though it's less common.

🔍 Quality Control and Packaging

Before packaging, each batch undergoes quality control tests such as physical tests, assay, dissolution, and content uniformity to ensure compliance with specifications. Only after passing these checks are tablets packed in blister packs, strips, or bottles. Proper packaging ensures the tablets remain protected and ready for market distribution. Strict adherence to quality standards is essential to safeguard patient safety and maintain product efficacy.

🛡 Importance of Quality and Process Control

The tablet manufacturing process is intricate and involves multiple stages, all of which must be carefully managed to ensure product quality. Failure to follow these steps could compromise tablet safety and efficacy, defeating the purpose of manufacturing.
