Department of Pharmacy, Annamalai University, Annamalai Nagar, Tamil Nadu , India The optimized high-shear vet granulation process variables quantified on 1.5 kg batch were scaled up to 90 kg production scale for the manufacture of. mebendazole tablets to achieve the scale invariant drug release. The matching granulation properties and dissolution profiles were obtained by the use of a constant impeller-tip velocity in all the high-shear scale-up mixers used. The resultant end point of granulation remained reproducible regardless of scale of manufacture.
