Question

Quizplus · Accepted Answer

Vehicles are substances used to dissolve, suspend, or integrate other substances (like drugs) without changing their physical properties. A salt solution of the drug is not a vehicle but rather a form of the drug itself, possibly dissolved in a vehicle. Aqueous vehicles, non-aqueous water-miscible vehicles, and non-aqueous water-immiscible vehicles are all examples of types of vehicles used in pharmaceutical formulations.
