Here's why:

* Enteric coating: This special coating is designed to resist the acidic environment of the stomach. It protects the active ingredients from being broken down prematurely.

* Small intestine: The small intestine has a higher pH (more alkaline) than the stomach. This allows the enteric coating to dissolve, releasing the medication for absorption.

Key takeaway: Nonenteric film-coated tablets are formulated to deliver their active ingredients further down the digestive tract, in the small intestine.
