Question 1 of 5
Where do enteric coated tablets typically disintegrate in the body?
Correct Answer: B
Rationale: The correct answer is B: Duodenum. Enteric-coated tablets are designed to withstand the acidic environment of the stomach and only disintegrate in the alkaline environment of the duodenum. The duodenum is the first part of the small intestine, where the pH is higher due to the presence of bicarbonate from the pancreas. This delayed release allows for protection of the drug from stomach acid and enzymes.
Choices A, C, and D are incorrect because enteric-coated tablets are specifically formulated to avoid disintegration in the esophagus, stomach, or colon.
