Question 69

Ophthalmic drops must be compounded under sterile conditions.

Ophthalmic drops require sterility to prevent contamination that could lead to serious infections or complications in the eye. Therefore, they must be prepared under sterile conditions to ensure patient safety.

A) Rectal creams

Rectal creams do not require sterile conditions because they are administered in a location that is less prone to infection compared to the eye. The rectal route allows for non-sterile preparations as long as they are used appropriately and do not compromise patient safety.

B) Ophthalmic drops

Ophthalmic drops must be compounded under sterile conditions to prevent any risk of contamination that could lead to ocular infections. This requirement is critical to ensure the safety and efficacy of the medication when administered to the sensitive eye area.

C) Topical ointments

Topical ointments are typically applied to the skin and do not need to be compounded under sterile conditions. While cleanliness is important, the risk of infection is significantly lower than with products intended for ocular use.

D) Oral suspensions

Oral suspensions can be compounded without strict sterile conditions, as they are ingested and the gastrointestinal tract has mechanisms to handle non-sterile substances. The primary concern is ensuring that the ingredients are safe and effective for consumption.

Conclusion

Ophthalmic drops are uniquely sensitive to contamination, necessitating sterile compounding practices to protect patients from potential infections. In contrast, rectal creams, topical ointments, and oral suspensions do not share the same level of risk and can be safely compounded without strict sterility, making B the only correct choice for this question.
