was performed in a texture analyzer a tablet was held on a net that was then attached to a u00bc u2033 stainless steal ball probe the disintegration medium was 5 ml of water in a 50 ml beaker the height of water was barely enough to submerge the tablet and the water temperature was kept at 37 u00b1 1 u00b0 c the texture analyzer was instructed to apply a small force 20 g when the tablet hit the bottom of the beaker the time for disintegration onset and total disintegration time was recorded compressibility fast dissolving tablets in general are soft and need to be blister packaged directly off the tablet press the tablets manufactured according to the invention can be compression or wet granulation for fast dissolving tablets containing a coated active it is important to compress at the lowest force possible so that the coating will not be ruptured under compression with the melt granulation approach tablets that are robust enough to withstand packaging right off the tablet press were obtained using a compression force as low as 2 kn whereas for a similar direct compression formulation acceptable tablets could not be obtained at compression forces below 5 kn fig1 hardness and friability although the melt granulation tablets had a lower hardness compared to direct compression tablets that are compressed at the same force fig1 the melt granulation tablets were somewhat pliable and less fragile as illustrated in fig2 the softest melt granulation prototype with a hardness of about 0.
