Question 66

An incorrect generic substitution would occur if a pharmacy dispensed ramipril for Vasotec.

Dispensing ramipril for Vasotec constitutes an incorrect generic substitution because Vasotec is the brand name for enalapril, while ramipril is a different medication with distinct pharmacological properties.

A) ramipril for Vasotec.

This option is incorrect because ramipril and enalapril (Vasotec) are not the same medication. They belong to the same class of drugs (ACE inhibitors) but are different compounds with different indications and side effects. Therefore, substituting ramipril for Vasotec would not provide the same therapeutic effect.

B) pregabalin for Lyrica.

This option is incorrect as well. Pregabalin is the generic name for Lyrica. Therefore, dispensing pregabalin for Lyrica is a correct generic substitution, as both names refer to the same medication and its therapeutic effects.

C) allopurinol for Zyloprim.

This option is also incorrect. Allopurinol is the generic name for Zyloprim. Thus, substituting allopurinol for Zyloprim is appropriate and aligns with the standard of practice for generic medications.

D) gemfibrozil for Lopid.

This option is similarly incorrect. Gemfibrozil is the generic name for Lopid. Therefore, dispensing gemfibrozil for Lopid represents a correct substitution, as both refer to the same active ingredient.

Conclusion

The correct answer is A because ramipril is not interchangeable with enalapril (Vasotec), leading to potential therapeutic discrepancies. All other options (B, C, and D) represent valid generic substitutions, as they involve dispensing the appropriate generic medication for the corresponding brand name.
