Abstract
During the development of a tablet formulation of a cohesive, fluffy investigational drug, a novel moisture-activated dry granulation (MADG) process was studied in comparison with two conventional granulation methods, i.e., wet granulation and dry granulation with a roller compactor, as well as with a direct compression formulation method. The MADG method produced granules with excellent flowability which were equivalent in a number of ways to those produced by either conventional wet granulation or dry granulation methods and which were much better than the powder blend from the direct compression formulation. The tablets prepared using the MADG method had better content uniformity than those made using material from wet and dry granulation processes. Other tablet properties, such as weight variation, friability and dissolution, were similar among the tablets produced by the four processes
