Granules are manufactured for various reasons:
Advantages of Granules:
1. Improved flowability: Granules have better flow properties, making them easier to handle and process.
2. Enhanced compressibility: Granules can be compressed more easily, resulting in stronger tablets.
3. Reduced dustiness: Granules minimize dust generation, improving worker safety and reducing contamination.
4. Better uniformity: Granules ensure consistent particle size, leading to more uniform tablets.
5. Increased stability: Granules can improve the stability of active ingredients.
Pharmaceutical Applications:
1. Tablet manufacturing: Granules are used as intermediates for tablet production.
2. Capsule filling: Granules are filled into capsules for oral delivery.
3. Sachet filling: Granules are filled into sachets for single-dose packaging.
4. Topical preparations: Granules are used in creams, ointments, and lotions.
