What type of medication requires shaking before administration due to suspended particles?

The type of medication that requires shaking before administration due to suspended particles is a suspension. Suspensions are liquid formulations in which solid particles are dispersed throughout a liquid medium but do not completely dissolve. These suspended particles tend to settle at the bottom of the container over time, which is why it is essential to shake the suspension before measuring and administering the dosage. Shaking ensures that the particles are evenly distributed throughout the liquid, providing an accurate dose of the medication.

In contrast, elixirs and syrups are solutions where the active ingredients are completely dissolved in the liquid. These do not contain suspended particles that would require shaking, as they are homogeneous mixtures where the components are evenly distributed. Liquid medications is a broad category that includes various forms; however, not all liquid medications are suspensions and thus do not necessarily require shaking. Therefore, the specific requirement for shaking is characteristic of suspensions.
