Containers that contain preservatives for multiple doses of medication are called.

• A. Multidose Vials
• B. Single-Dose Vials
• C. Vials
• D. Ampules

Answer: (A)

Multidose vials are designed to be used more than once, which is why they include preservatives to prevent microbial growth between withdrawals. They usually have a stable rubber stopper that allows repeated, sterile access with a syringe while keeping the contents safe for use over multiple doses. This is what the term describes—the container that holds preservatives to permit multiple doses. Single-dose vials, in contrast, are meant for one use and are discarded after a single withdrawal; ampules are opened and cannot be resealed for reuse.
