Which product is NOT designed for sterile compounding?

The injector pen is primarily designed for delivering medication in a pre-measured dose, especially for self-administration of drugs such as insulin. It is not classified as a sterile compounding product because it does not involve the preparation or mixing of sterile medications in a clean room environment, which is essential for maintaining sterility during the compounding process.

In contrast, products like ADD-vantage, MINI-BAG, and ADD-A-VIAL are specifically designed for sterile compounding. ADD-vantage systems allow for mixing of drugs in a sterile environment, MINI-BAGs provide a sterile container for drug administration, and ADD-A-VIAL facilitates the process of adding a drug to a sterile IV solution, all of which are critical practices in ensuring the sterility and efficacy of compounded medications.
