Which of the following is an example of a non-sterile compounding product?

Topical preparations applied to the skin are considered a form of non-sterile compounding because they are not intended for injection, ingestion, or entry into sterile tissue. Non-sterile compounds generally include products that are applied externally, such as creams, ointments, and gels that are used on intact skin or mucous membranes.

In contrast, injections for intravenous use, ophthalmic drops, and aqueous bronchial inhalations are all categorized as sterile preparations since they are meant for administration into usually sterile areas of the body or involve contact with sterile surfaces. These products must be manufactured under strict conditions to eliminate any microbial contamination, ensuring safety for patients receiving these treatments. Thus, identifying topical preparations as non-sterile reflects the standard definitions used in compounding practice.
