True or False: Enteric polymers must not dissolve in the stomach.

True or False: Enteric polymers must not dissolve in the stomach.

• A. True
• B. False
• C. Only partial dissolution
• D. Depends on pH

Answer: (A)

Enteric polymers are specifically designed to resist dissolution in the acidic environment of the stomach. This feature is critical for their intended use, which typically involves protecting the active pharmaceutical ingredient from degradation due to gastric acid or preventing irritation of the gastric mucosa. These polymers remain intact until they reach the more neutral pH of the intestine, where they then dissolve and release the drug. The design of enteric polymers relies on their chemical properties, which are selected to ensure they are stable in low pH conditions but become soluble in the higher pH typical of the intestinal tract. This characteristic plays a significant role in the bioavailability of certain medications that require bypass of the stomach for optimal absorption. Therefore, stating that enteric polymers must not dissolve in the stomach accurately reflects their necessary function.
