After dilution, it can be crucial the drug be homogeneously dispersed ahead of administration.
The key distinction between a suspension and syrup more info lies inside the solubility from the components. Inside of a suspension, the stable particles are not soluble from the liquid medium and so continue being dispersed, typically needing shaking right before use to ensure uniformity.
Simple COATED TABLETS Classically, tablets are already coated with sugar used from aqueous suspensions that contains insoluble powders such as starch, calcium carbonate, talc, or titanium dioxide, suspended via acacia or gelatin. For purposes of identification and esthetic worth, the skin coatings might be colored.
