Tablet Manufacturing Explained : Different Stages of Tablet Manufacturing Process

Summary

This video provides an in-depth overview of the tablet manufacturing process, a series of steps required to produce quality tablets. It explains key stages such as blending, granulation, drying, compression, coating, polishing, and packaging. Each step is crucial in ensuring the uniform distribution of active ingredients, proper drug release, and maintaining the quality of the product. The video also covers methods like wet and dry granulation, fluid bed drying, and spray coating, emphasizing the importance of quality control throughout the process to ensure patient safety.

Takeaways

• 💊 The tablet manufacturing process involves a series of steps to ensure a high-quality product, including blending, granulation, drying, compression, coating, and packaging.
• 🧪 Tablets are solid dosage forms taken orally, made from a mix of active ingredients and excipients, which vary depending on the type of tablet.
• 🔄 Blending ensures even distribution of active ingredients throughout the tablet and is done using various types of blenders like V cone and double cone blenders.
• 🌐 Granulation converts powders into granules, improving material flow for compression. There are two types of granulation: wet and dry.
• 🌀 Granules are dried using methods like fluid bed drying, which helps remove moisture before tablet compression.
• ⚙️ Compression involves pressing granules into tablets, with size, shape, and drug release properties controlled by compression force.
• 🎨 Tablet coating improves appearance, stability, and can mask unpleasant tastes. Common coating methods include dipping and spraying.
• ✨ Polishing tablets removes sharp edges, making them smooth and shiny for better handling and appearance.
• 🖋 Branding tablets by printing names or strength using edible inks is rare but used by some companies for identification.
• 📦 Quality control tests, including dissolution and content uniformity, are conducted before tablets are packaged and shipped for sale.

Q & A

What is the main objective of the tablet manufacturing process?

The main objective is to follow a series of steps to produce a high-quality tablet product, ensuring that all ingredients are processed and tested properly at each stage.

What are the key ingredients used in tablet manufacturing?

Tablets are manufactured using a combination of active ingredients and excipients. The quantity and type of excipients depend on the type of tablet being produced.

Why is blending important in the tablet manufacturing process?

Blending ensures that active ingredients are evenly distributed throughout the excipients, resulting in a homogeneous mixture which is critical for ensuring consistent tablet quality.

What are the two types of granulation, and how do they differ?

The two types of granulation are wet and dry granulation. Wet granulation involves adding a liquid to convert powder into granules, while dry granulation forms granules without the use of any liquid.

Why is granulation considered a crucial step in tablet manufacturing?

Granulation improves the flow of material, making the compression process easier. It also affects drug release and ensures proper tablet formation.

What equipment is commonly used for drying granules, and how does it work?

Tray dryers and fluid bed dryers (FBD) are commonly used. Fluid bed dryers use hot air that passes through the material, removing moisture and solvents to achieve the required drying level.

How does compression affect the physical properties of a tablet?

Compression affects the size, shape, hardness, thickness, and friability of the tablet, as well as the dissolution rate and release of active ingredients.

What are the benefits of coating tablets?

Coating improves the tablet’s appearance and stability, reduces the dissolution rate, masks unpleasant taste, and provides a unique identification for the brand.

What is the role of quality checks in the tablet manufacturing process?

Quality checks ensure that the tablets meet specifications. Physical tests, dissolution, disintegration, and content uniformity are common tests performed before packaging.

What happens to the tablets after they pass quality checks?

After passing quality checks, the tablets are packaged according to customer requirements, typically in blisters, strips, or bottles, and are then shipped to the market for sale.
