According to the material, what describes a vehicle?

• A. A pill
• B. A sugar coating
• C. A gas
• D. A liquid like oil or water in which a drug dissolves

Answer: (D)

A vehicle is the medium that carries the drug into the body, allowing it to be dissolved or dispersed and thus absorbed. The best description is a liquid such as oil or water in which the drug dissolves, because this medium directly enables the drug to enter the system. A pill is a solid dosage form, not the carrier; a sugar coating is just part of the pill’s exterior and does not serve as the dissolving carrier; and while a gas can deliver some inhaled drugs, the standard concept described here focuses on a liquid medium in which the drug dissolves.
