Question 22

A patient would receive an incorrect generic substitution if a pharmacy dispensed Rivaroxaban for Eliquis.

Rivaroxaban and Eliquis are not interchangeable as they are different medications. Eliquis is the brand name for apixaban, while rivaroxaban is marketed under its own brand name, which means substituting one for the other would not be appropriate.

A) Duloxetine for Cymbalta

Duloxetine is the generic name for Cymbalta, making this substitution correct. A pharmacy dispensing duloxetine for Cymbalta is providing the same active ingredient and therefore is an acceptable generic substitution.

B) Lisinopril for Zestril

Lisinopril is the generic version of Zestril, which means substituting lisinopril for Zestril is correct. This option does not represent an incorrect generic substitution, as both medications contain the same active ingredient.

C) Rivaroxaban for Eliquis

Rivaroxaban cannot be substituted for Eliquis because they are different drugs with distinct properties and indications. Rivaroxaban is the generic name for a different medication, while Eliquis is the brand name for apixaban, thus making this option the correct answer to the question.

D) Finasteride for Proscar

Finasteride is the generic name for Proscar, making this substitution valid. A pharmacy providing finasteride for Proscar is supplying the same medication and is therefore not an incorrect substitution.

Conclusion

Rivaroxaban for Eliquis represents an incorrect generic substitution because they are distinct medications with different active ingredients and therapeutic uses. In contrast, all other options involve correct substitutions as they feature the same active ingredients under their respective brand names. Understanding the differences between generic and brand names is crucial in ensuring safe medication practices.
