Question 65

Adsorption is most likely to cause a medication to lose potency.

Adsorption can cause a medication to lose potency by binding the drug to surfaces or materials, thereby reducing the amount of the active ingredient available for therapeutic effect.

A) lose potency

This option is correct because adsorption involves the adherence of molecules to surfaces, which can sequester the active pharmaceutical ingredient away from its intended target, leading to a decrease in potency. This phenomenon is particularly critical in pharmaceuticals where maintaining the correct concentration is essential for efficacy.

B) become contaminated

This option is incorrect as adsorption does not inherently lead to contamination. Contamination typically refers to the introduction of foreign substances or microbes, which is a separate issue from the process of adsorption itself.

C) require refrigeration

This option is also incorrect. The requirement for refrigeration is usually related to the stability of the medication and its active ingredients rather than adsorption. While some medications do need to be refrigerated, adsorption does not directly influence this requirement.

D) trigger anaphylaxis

This option is incorrect because anaphylaxis is an acute allergic reaction that is not caused by adsorption. Anaphylaxis is usually linked to immune responses to allergens, not the physical interaction of a drug with surfaces.

Conclusion

In summary, the correct answer is that adsorption is most likely to cause a medication to lose potency, as it can effectively reduce the availability of the active ingredient. Other options do not accurately describe the effects of adsorption, highlighting its unique impact on drug efficacy rather than contamination, refrigeration needs, or allergic reactions.
