All of the following reduce production of gastric acid in the stomach, EXCEPT

Correct Answer: D

Rationale: The correct answer is D, Cetirizine hydrochloride. Cetirizine is an antihistamine used to treat allergies and does not have any effect on reducing gastric acid production. Aluminium hydroxide (A) is an antacid that neutralizes stomach acid. Cimetidine (B) is an H2 blocker that reduces acid production. Omeprazole (C) is a proton pump inhibitor that also decreases stomach acid production. Therefore, D is the correct answer as it does not have any impact on gastric acid levels.

Correct Answer: C

Rationale: Increased binding of drugs to plasma proteins leads to a decrease in the concentration of free drug available for elimination. This results in a longer half-life of the drug as it takes longer for the bound drug to be released and metabolized. This does not directly impact drug-drug interactions or renal filtration, as binding to plasma proteins affects the distribution and elimination of the drug. Therefore, the correct answer is C.
