What is a suspension medication?
This a non-homogeneous suspension......
And this is prepared by adding a known quantity of medication to some liquid (typically water), which forms a suspension when shaken. The suspension is so formulated, that when the suspension is shaken, a given volume contains the correct dose of medicine. As you probably know from personal experience, sometimes they are hard to swallow, and for this reason, they probably would not be administered to young children.
The medicine could also be delivered as an aerosol, in which the medicine is also delivered in 2 phases.
