What are common routes of administration for compounded sterile preparations?

The correct choice highlights intravenous, intramuscular, and subcutaneous routes as common methods for administering compounded sterile preparations. These routes are particularly important in the context of sterile compounding because they involve the parenteral administration of medications directly into the body, bypassing the gastrointestinal system.

Intravenous administration allows for rapid delivery and immediate effect, making it crucial for urgent care situations. Intramuscular injections are effective for vaccines and certain medications that require deeper delivery into muscle tissue for absorption. Subcutaneous injections are commonly used for medications like insulin or certain biologics, providing a slower, more sustained absorption compared to intravenous or intramuscular routes.

The significance of using sterile techniques in these methods cannot be overstated, as any contamination can lead to severe complications, including infections. Therefore, training in sterile compounding focuses on ensuring that these routes of administration are executed safely and effectively.
