Question 40

Desipramine and desmopressin are an ISMP look-alike/sound-alike pair.

Desipramine and desmopressin are indeed an ISMP look-alike/sound-alike pair due to their similar spellings and pronunciations, which can lead to medication errors if not properly distinguished.

A) Desipramine and desmopressin

This option is correct as both drugs have names that are visually and phonetically similar. This similarity can increase the risk of confusion and potential medication errors, which is why they are categorized as a look-alike/sound-alike pair by the ISMP.

B) Chlordiazepoxide and chlorpromazine

While both names contain similar prefixes, they are not classified as a look-alike/sound-alike pair by ISMP. The difference in the latter part of the names and their therapeutic uses make them less likely to be confused in a clinical setting.

C) Fluoxetine and fluticasone

Although fluoxetine and fluticasone share some phonetic similarities, they do not qualify as an ISMP look-alike/sound-alike pair. The distinct endings and their functions as an antidepressant and a corticosteroid, respectively, further differentiate them.

D) Humalog and Humira

Humalog and Humira may appear similar, but they are not categorized as an ISMP look-alike/sound-alike pair. The differences in the drug classes (insulin analog versus monoclonal antibody) and the context in which they are used help to mitigate the chances of confusion.

Conclusion

Desipramine and desmopressin are correctly identified as a look-alike/sound-alike pair due to their potential for causing medication errors from confusion. The other options, while they may have some similarities, do not meet the criteria set by the ISMP for such pairs, demonstrating the importance of clear distinctions in medication naming to ensure patient safety.
