Which abbreviation refers to a liquid dosage form that is a solution?

• A. Suspension
• B. Solution
• C. Syrup
• D. Serum

Answer: (B)

In a liquid dosage form, the key idea is how the drug is distributed within the liquid. A solution is a homogeneous mixture where the drug is dissolved in the solvent at the molecular level. Because it’s fully dissolved, there are no visible particles and the liquid is uniform throughout. This is what makes it a true solution. A suspension, on the other hand, contains solid drug particles that are dispersed but not dissolved; those particles can settle out over time and require shaking before use. A syrup is a type of liquid dosage form that is a concentrated sugar solution in which medicines can be dissolved, so it is a solution as well, but it’s specifically described by its sugary, viscous vehicle. Serum is not a typical medicinal liquid dosage form; it refers to a biological fluid, not a standard drug preparation.
