AEROSIL R 972 is a fumed silica after treated with Dimethyldichlorosilane. Flame extinction by Aerosil via heat loss from the reaction zone is controlled by the specific surface area of the powder, which amounts to hundreds of square meters per kilogram. Shear thickening behavior occurs when a colloidal suspension transitions from a stable state to a state of. These are of particular use for the process of the invention which implies the preliminary compaction of powders and/or granules before the final compression into a tablet. MATERIALS AND METHODS: Methods: The sublingual tablets of Nifedipine were prepared using different combinations of Crospovidone and croscarmellose sodium (CCS) as super disintegrants, mannitol as a diluents, Aspartame as sweetening agent, alcoholic solution of PVP (10 % w/v) as binder and aerosil with talc as a flow promoters (Table 1). Lactose (Wilfrid Smith Ltd. The French vaccine manufacturer, Pasteur Merieux, used Aerosil adsorption with elution conditions similar to those described above for the production of a commercial plasma-derived HBsAg vaccine (34).
