Composed of a solute dissolved in a solvent describes which term?

• A. Liquid medications
• B. Suspensions
• C. Tinctures
• D. Spirits

Answer: (A)

A homogeneous mixture where a solute is dissolved in a solvent describes a solution, and in pharmacology this concept is most broadly captured by the category of liquid medications. Liquid medications include formulations where the substance is fully dissolved to form a uniform liquid, as opposed to suspensions where particles remain dispersed and are not dissolved. Tinctures and spirits are specific alcohol-based liquid preparations with particular contents and solvent types, so they’re more specialized examples rather than the general description of a dissolved-solute liquid. Therefore, the term that best matches the idea of a solute dissolved in a solvent within a liquid medication context is liquid medications.
