Question

Enteric coating is done with the following material

• A. Sodium starch glycolate
• B. Cellulose acetate phthalate
• C. Starch
• D. PEG-400

Hint:

Enteric coatings are usually made from materials like cellulose acetate phthalate that are stable in acidic conditions but dissolve in the intestines.

Answer 1

The Correct Option is B

Step 1: Understanding enteric coating.
Enteric coating is a polymer barrier applied to oral medication to prevent it from dissolving in the stomach. It protects the drug from acidic stomach conditions and releases it in the intestines.
Step 2: Analyzing the options.
(A) Sodium starch glycolate: This is used as a disintegrant, not for enteric coating.
(B) Cellulose acetate phthalate: Correct — This is a common material used for enteric coating as it resists stomach acid and dissolves in the alkaline environment of the intestines.
(C) Starch: Starch is a binding agent, not suitable for enteric coating.
(D) PEG-400: This is a plasticizer, not used for enteric coating.
Step 3: Conclusion.
The correct answer is (B) Cellulose acetate phthalate as it is the material used for enteric coatings.
