What term describes the liquid in which a drug dissolves?

• A. Vehicle
• B. Bolus
• C. Suspension
• D. Capsule

Answer: (A)

When a drug is dissolved for absorption, the liquid that carries it is called the vehicle. The vehicle is the solvent or carrier in which the drug dissolves, and it can be water, saline, alcohol, or another solvent chosen to optimize solubility, stability, and how the drug is absorbed. The other terms describe dosage forms or administration methods rather than the dissolving medium: a bolus is a single dose given quickly, a suspension is a liquid with undissolved particles dispersed in it, and a capsule is a solid dosage form with a shell. So the liquid in which the drug dissolves is the vehicle.
