We proposed plotting 'Compactability' on the x-axis against'Manufacturability' on the y-axis to allow visual evaluation of 'Tableting properties'. Various types of tableting failure occur in commercial drug production and are influenced by the amount of lubricant used and the shape of the punch. We used the GTP-1 to measure'Tableting properties' with different amounts of lubricant and compared the results with those of tableting on a commercial rotary tableting machine. Tablets compressed with a small amount of lubricant showed bad 'Manufacturability', leading to sticking of powder on punches.We also tested various punch shapes. The GTP-1 correctly predicted the actual tableting results for all punch shapes. With punches that were more likely to cause tableting failure, our system predicted the effects of lubricant quantity in the tablet formulation and the occurrence of sticking in the rotary tableting machine.展开更多

We plotted "Compactability" on the x-axis against "Manufacturability"on the y-axis to allow visual evaluation of "Tableting properties". Here, we examined whether this evaluation method can be used in the formulation design of tablets prepared by wet granulation. We used the GTP-1 to measure "Tableting properties" with different amounts of binder, disintegrant, and lubricant, and compared the results with those of tableting on a commercial rotary tableting machine. Tableting failures(capping and binding in particular) occurred when samples that had been evaluated as having poor "Compactability" or"Manufacturability" on the GTP-1 were compressed on the rotary tableting machine. Thus,our evaluation method predicted tableting failure at the commercial scale. The method will prove useful for scaling up production.展开更多
