The sedimentation volume (F) is defined as the ratio of final or ultimate volume to the suspension volume. If the volume of sedimentation in a flocculated suspension equal to the original volume of suspension, then F=1 is pharmaceutically acceptable. When F=0 it means the total drug has sedimented and volume of sediment is negligible. So, more the volume of F more will be therapeutic acceptance. In this study two types of suspension were studied where aluminium hydroxide suspension classed as type-I and sodium-bi-carbonate, magnesium trisilicate, magnesium carbonate suspension classed as ty pe-II suspension. It was observed that the sedimentation volume is more in case of type-I suspension rather than type-II suspension.
