Question 64

Promethazine suppositories should be stored in a pharmacy under the same conditions as Humira injection.

Both Promethazine suppositories and Humira injections require refrigeration to maintain their effectiveness and stability. Proper storage conditions are critical for ensuring the safety and efficacy of these medications.

A) Humira injection

This option is correct because Humira injections are biologics that must be stored in the refrigerator between 2°C to 8°C (36°F to 46°F) to prevent degradation. Similarly, Promethazine suppositories also require refrigeration to maintain their potency, making this option the most appropriate for comparison.

B) Lactulose solution

Lactulose solution does not require refrigeration and can be stored at room temperature. This difference in storage requirements means that it cannot be directly compared to Promethazine suppositories, which must be kept cold.

C) Pramosone cream

Pramosone cream is typically stored at room temperature and does not require refrigeration. The storage conditions for this topical medication differ significantly from those of Promethazine suppositories, making this option incorrect.

D) Bisacodyl suppositories

Bisacodyl suppositories are also typically stored at room temperature rather than in refrigeration. While they are both suppositories, the storage conditions do not align with those of Promethazine, rendering this option incorrect.

Conclusion

The correct answer is A, as both Promethazine suppositories and Humira injections require refrigeration for proper storage, ensuring their stability and effectiveness. Options B, C, and D fail to meet the necessary storage conditions, as they can be safely stored at room temperature, highlighting the importance of appropriate storage practices for different medications.
