In pharmaceutical suspensions, what does the dispersed phase refer to?

Explanation:
In a pharmaceutical suspension, the dispersed phase is the solid drug particles that are distributed as tiny solids within the liquid vehicle. The liquid that carries them is the dispersion medium (the continuous phase). A gas phase would only be relevant in foams, and emulsion droplets pertain to emulsions (liquid droplets in another liquid), not suspensions. So the solid drug particles are the dispersed phase.
