According to the Institute for Safe Medication Practices (ISMP) List of Confused Drug Names, which pair is considered a risk?

Rationale

Amiodarone and amantadine

According to the Institute for Safe Medication Practices (ISMP) List of Confused Drug Names, **amiodarone and amantadine** are considered a high-risk look-alike/sound-alike (LASA) pair. Their similar spelling and pronunciation can lead to medication errors, which may result in serious clinical consequences due to the very different therapeutic uses of the two drugs.

A (Amiodarone and amantadine) CORRECT

This is correct. ISMP identifies this pair as a LASA risk because the similarity in name can easily cause confusion during prescribing or dispensing.

B (Atorvastatin and simvastatin) YOUR ANSWER

This is incorrect. While both are statins, their names are sufficiently distinct, and they are not listed by ISMP as a commonly confused drug name pair.

C (Furosemide and famotidine) YOUR ANSWER

This is incorrect. Despite some similarity in spelling, this pair is not highlighted by ISMP as a high-risk confused drug name pair.

D (Cephalexin and ciprofloxacin) YOUR ANSWER

This is incorrect. These antibiotic names differ enough in spelling and pronunciation that they are not considered a major LASA risk by ISMP.

Conclusion

Look-alike/sound-alike drug names can significantly increase the risk of medication errors. Amiodarone and amantadine are a classic example of a high-risk LASA pair according to ISMP, highlighting the need for careful verification when prescribing or dispensing these medications.
