The effect of binder type and concentration on six high dose drugs was evaluated. The drugs which are used in this experiment are already in market and are available at a very high dose of 500mg and above. Three binders were used in the work at two different user levels. The binders are chosen of different chemistries so in order to predict a optimized formulation for each of the drug. The brittle fracture index of the formulation is calculated by compressing tablets with hole, the hole is an inbuilt defect which will help in propagation of crack into the tablet and enable capping and...
