56. Once reconstituted, ciprofloxacin oral suspension stored in a refrigerator is stable for how many days?
Answer: C
Ciprofloxacin oral suspension is stable for 14 days when stored in a refrigerator.
Once reconstituted, ciprofloxacin oral suspension can be safely stored in a refrigerator for up to 14 days before it should be discarded.
A) 3
While ciprofloxacin may have a short stability period under certain conditions, it is not limited to just 3 days. This option inaccurately represents the stability timeframe of the suspension, as it is known to last longer when properly refrigerated.
B) 7
Seven days is also insufficient time for the stability of reconstituted ciprofloxacin oral suspension. Although it may be stable for a week, the established guideline indicates that it can be stored safely for a longer duration.
C) 14
This option accurately reflects the recommended stability period for ciprofloxacin oral suspension when stored in a refrigerator. Studies and guidelines confirm that it remains effective and safe for use within this 14-day window.
D) 28
Storing ciprofloxacin oral suspension for 28 days exceeds the recommended stability period. This option is incorrect as it suggests a duration that may compromise the medication's effectiveness and safety.
Conclusion
Ciprofloxacin oral suspension is definitively stable for 14 days when refrigerated, which aligns with established pharmaceutical guidelines. Options A, B, and D do not accurately reflect the stability timeframes, making them incorrect. Therefore, C is the only correct answer based on the information regarding the storage of reconstituted ciprofloxacin.
