Abstract
This comprehensive review explores modern granulation techniques in pharmaceutical dosage forms along with conventional methods, focusing on dry granulation and wet granulation. Dry granulation techniques, including slugging, roller compaction, and pneumatic dry granulation, are dissected with thorough analyses of their processing methods, advantages, disadvantages, and diverse applications. The article delves into eleven wet granulation techniques, offering insights into high-shear granulation, low-shear granulation, fluidized bed granulation, reverse wet granulation, steam granulation, moisture-activated dry granulation, melt granulation, freeze-dry granulation, foam granulation, thermal adhesion, and twin screw wet granulation. Each method is scrutinized, providing a comprehensive understanding of its processing steps, merits, drawbacks, and practical applications in pharmaceutical manufacturing. The article serves as a valuable resource for researchers, pharmaceutical professionals, and students, offering a nuanced exploration of diverse granulation techniques vital in drug formulation. This synthesis of information aims to enhance the understanding of granulation processes, facilitating informed decision-making in pharmaceutical development and manufacturing.
