Question 41

Calcitonin is an injectable medication that should be stored under refrigeration long-term prior to dispensing.

Calcitonin is a medication that requires refrigeration to maintain its stability and efficacy when stored long-term before dispensing. Proper storage is essential for ensuring that the medication remains effective when administered to patients.

A) Cyclopentolate

Cyclopentolate is typically used as an ophthalmic agent and does not require refrigeration for storage. It is stable at room temperature, making it unsuitable for this question as it does not meet the criteria of needing long-term refrigeration.

B) Calcitonin

Calcitonin is indeed an injectable medication that must be stored under refrigeration to preserve its potency and effectiveness over time. This requirement aligns with the question's focus on long-term storage conditions for injectable medications.

C) Clindamycin

Clindamycin is an antibiotic that is often available in both oral and injectable forms. However, it does not require refrigeration for long-term storage, as it can be kept at room temperature, thus making it an incorrect choice in this context.

D) Chlorambucil

Chlorambucil is an oral medication used in cancer treatment and does not require refrigeration for storage. Its stability at room temperature disqualifies it as a correct answer in the context of injectable medications needing refrigeration.

Conclusion

Calcitonin is the only injectable medication listed that must be stored under refrigeration long-term prior to dispensing, ensuring its stability and effectiveness. The other options either do not require refrigeration or are not injectable medications, confirming that they do not meet the criteria of the question.
