Question 25

Exposure to extreme heat can cause omeprazole suspension decomposition.

Omeprazole suspension is sensitive to environmental conditions, and exposure to extreme heat can lead to its degradation. This results in a loss of efficacy and potential safety concerns for the medication.

A) Gentle shaking

Gentle shaking of the omeprazole suspension is generally not a cause for decomposition. In fact, it is often necessary to ensure uniform distribution of the medication prior to administration, and does not significantly impact the stability of the drug.

B) Exposure to extreme heat

Exposure to extreme heat is known to cause chemical degradation of many pharmaceutical compounds, including omeprazole. High temperatures can accelerate the breakdown of the active ingredient, rendering the suspension less effective or potentially harmful.

C) Refrigeration

Refrigeration is typically a recommended storage condition for many medications, including omeprazole, to help maintain stability and prolong shelf life. Therefore, refrigeration does not contribute to decomposition and is often beneficial for the medication.

D) Storage in an opaque bottle

Storing omeprazole suspension in an opaque bottle is intended to protect it from light, which can be detrimental to its stability. This storage method helps to prevent decomposition rather than causing it.

Conclusion

Exposure to extreme heat is the definitive factor that can lead to the decomposition of omeprazole suspension, as it promotes the breakdown of the drug's active ingredients. Other options, such as gentle shaking, refrigeration, and opaque storage, do not adversely affect the medication's stability and, in some cases, support its preservation. Thus, B is the only option that correctly identifies a condition that can cause decomposition.
