Finally, drugs in suspension are chemically for preparation of tablets, suspensions etc., List Of Suspending Agents. Suspensions are unstable from a thermodynamic point of view but can be kinetically stable over a longer period of time, which in turn can determine a suspension's shelf life. Solutions, suspensions, colloids, and other dispersions are similar but have characteristics that set each one apart from the others. This type of suspension has been universally used before drawing the independent front wheel suspension. A solvent is a substance that dissolves another substance forming a solution. A solution is a mixture formed when one or more solutes dissolve in a solvent. If a liquid is suspended in another liquid, it is called an emulsion. that they tend to settle over time leading to a lack of uniformity of dose.
