How does pharmaceutical suspensions work?

Pharmaceutical suspensions are heterogeneous mixtures in which solid drug particles are dispersed in a liquid medium. The solid particles are not dissolved but remain suspended, allowing for controlled release and absorption of the medication. To maintain stability and ensure uniform distribution, suspensions often include suspending agents or stabilizers. When administered, the liquid medium aids in swallowing and helps the drug particles to disperse in the gastrointestinal tract for absorption.
