Suspensions are generally found in medications where specific drug particles are not soluble in liquid mediums. In advance of administration, these medicines typically involve shaking to make sure the drug is evenly dispersed.
PLAIN COATED TABLETS Classically, tablets are coated with sugar applied from aqueous suspensions made up of insoluble powders which include starch, calcium carbonate, talc, or titanium dioxide, suspended by way of acacia get more info or gelatin.
