Explanation:

Famotidine is an H2-receptor antagonist that reduces stomach acid production. Ketoconazole is an antifungal medication that requires an acidic gastric environment for optimal absorption. When taken with famotidine, the reduced stomach acid levels decrease ketoconazole's absorption, making it less effective. The other listed medications do not have a clinically significant interaction with famotidine.
