Question 28

Pantoprazole is an appropriate therapeutic substitution for omeprazole.

Both pantoprazole and omeprazole are proton pump inhibitors (PPIs) that are used to decrease stomach acid production, making pantoprazole a suitable alternative for patients requiring similar therapeutic effects.

A) Mebendazole

Mebendazole is an anthelmintic medication used to treat parasitic worm infections. It does not share any pharmacological properties or therapeutic uses with omeprazole, making it an inappropriate substitution.

B) Ketoconazole

Ketoconazole is an antifungal medication that is used to treat fungal infections. While it does affect acid levels in the stomach, it does not serve the same purpose as omeprazole and is not indicated for treating conditions related to excessive stomach acid.

C) Fluconazole

Fluconazole is also an antifungal medication, primarily used to treat yeast infections. Similar to ketoconazole, it does not have the same action as omeprazole and would not be appropriate as a therapeutic substitution.

D) Pantoprazole

Pantoprazole is a proton pump inhibitor just like omeprazole, both of which function by inhibiting the proton pump in the stomach lining to reduce acid secretion. This makes pantoprazole a viable therapeutic substitution for patients requiring PPI therapy.

Conclusion

Pantoprazole is the only option that aligns with the therapeutic profile of omeprazole, as both are proton pump inhibitors. The other options listed do not serve the same purpose in managing stomach acid production, which is the core function being assessed in this question. Thus, pantoprazole is definitively the correct choice for therapeutic substitution.
