17. Which of the following ophthalmic drops should be refrigerated prior to dispensing?
Answer: D
Azithromycin ophthalmic drops should be refrigerated prior to dispensing.
Refrigeration is necessary for Azithromycin ophthalmic drops to maintain their stability and efficacy before use.
A) Timolol
Timolol ophthalmic drops do not require refrigeration and can be stored at room temperature. This medication is stable under standard storage conditions, making it convenient for patients and healthcare providers.
B) Brimonidine
Brimonidine ophthalmic drops also do not require refrigeration and are effective when stored at room temperature. There are no specific storage requirements that necessitate refrigeration for this medication.
C) Dorzolamide
Dorzolamide ophthalmic drops are stable at room temperature and do not need to be refrigerated. This allows for easier access and use by patients without the complications of temperature control.
D) Azithromycin
Azithromycin ophthalmic drops need to be refrigerated to preserve their effectiveness and prevent degradation. This specific requirement distinguishes it from other ophthalmic medications that can be stored at room temperature.
Conclusion
Azithromycin is the only ophthalmic drop in the list that necessitates refrigeration prior to dispensing, ensuring its stability and therapeutic effectiveness. The other options, Timolol, Brimonidine, and Dorzolamide, are all stable at room temperature and therefore do not require refrigeration, making them less complex in terms of storage.
