What is the significance of "enteric coated" tablets?

Enteric coated tablets are specifically designed to resist dissolution in the acidic environment of the stomach. This coating allows the tablet to pass through the stomach intact and dissolve in the more alkaline conditions of the intestines. This is significant for a few reasons: it helps protect the active ingredient from degradation by stomach acid, enhances absorption in the intestines, and can help minimize stomach irritation associated with certain medications.

For example, medications that can cause gastric irritation are often formulated with an enteric coating to prevent direct contact with the stomach lining until they reach the intestines, where the protective coating breaks down. By understanding this function, healthcare providers can make informed decisions about which medications are appropriate for patients based on their specific needs and conditions.
