What is an ampule used for?

An ampule is a sealed container that typically holds sterile liquid medications. Its primary purpose is to store sterile medications, often for injection purposes. The design of an ampule allows for the preservation of the sterility of its contents, as it is hermetically sealed, preventing contamination from external factors. When opened, the ampule is usually broken at the neck to access the sterile medication inside.

The other options do not accurately describe the primary function of an ampule. While solid medications are stored in various forms of containers, ampules are specifically meant for liquids. Non-sterile compounds are generally not stored in ampules since the sterility is crucial for many medical applications, particularly injections. Furthermore, while some ampules may contain liquid medications for mixing in oral solutions, their main use is not for dispensing oral solutions but rather for ensuring the safe and sterile administration of injectable medications.
