What term describes a liquid medication in which drug particles are not completely dissolved and must be shaken or stirred before use?

• A. Suspension
• B. Syrup
• C. Tincture
• D. Tablets

Answer: (A)

Suspension describes a liquid medicine in which the drug particles are not fully dissolved but are dispersed throughout the liquid. Because these solid particles can settle to the bottom, the mixture must be shaken or stirred before use to re-disperse them and create a uniform dose. This is different from a syrup or tincture, where the drug is dissolved in the liquid, and from tablets, which are solid forms rather than liquids. So, a liquid with undissolved drug particles that requires shaking to mix is a suspension.
