What Does Enteric Coated Mean

Have you ever wondered how some medications are able to bypass the harsh acidic environment of the stomach and reach the intestines intact? Enteric coated tablets provide the answer. This specialized coating, made from polymers that resist dissolution in stomach acid, allows the medication to pass through the stomach unaffected and deliver its therapeutic benefits in the intestines.

The concept of enteric coating dates back to the early 20th century when researchers sought ways to protect medications from stomach acid. Today, enteric coated tablets are commonly used for drugs that may cause irritation or is inactivated by the stomach's acidic environment. For example, non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin can irritate the stomach lining, but with enteric coating, these drugs can pass through the stomach unharmed and be absorbed in the intestines, reducing the chance of gastric side effects. Enteric coated tablets offer a valuable solution for ensuring effective drug delivery while minimizing potential gastric discomfort.

What Does Enteric Coated Mean: An Introduction

Enteric coating is a pharmaceutical technology used to protect drugs or supplements from the acidic environment of the stomach. The enteric coating is designed to remain intact in the stomach and dissolve in the alkaline environment of the small intestine, where the drug is then released. This process ensures that the drug or supplement is delivered to the target site of action and improves its effectiveness.

Why is Enteric Coating Used?

Enteric coating serves several purposes in pharmaceutical formulations:

  • Protection from stomach acid: Certain drugs, such as non-steroidal anti-inflammatory drugs (NSAIDs), can be irritating to the stomach lining. Enteric coating provides a barrier that prevents direct contact between the drug and the stomach, reducing the risk of irritation or ulcers.
  • Enhanced drug stability: Some drugs are susceptible to degradation in the acidic environment of the stomach. Enteric coating helps protect these drugs from degradation, preserving their effectiveness.
  • Delayed release: Enteric coating can be used to control the release of a drug over time. By delaying the dissolution of the coating, the drug is released gradually in the small intestine, providing a sustained effect.
  • Targeted delivery: Enteric coating allows drugs to bypass the stomach and reach the small intestine, where they can be absorbed more efficiently. This is particularly useful for drugs that are poorly absorbed in the stomach or those that need to be delivered to a specific region of the intestine.

How Does Enteric Coating Work?

The enteric coating is typically made from polymers that are resistant to gastric acid but dissolve in the alkaline environment of the small intestine. Examples of commonly used polymers include cellulose acetate phthalate (CAP), hydroxypropyl methylcellulose phthalate (HPMCP), and polyvinyl acetate phthalate (PVAP).

When a drug or supplement is enteric-coated, it is first processed into granules or tablets with the active ingredient and additives. Then, the enteric coating material is sprayed or applied onto the granules or tablets. The coating is usually applied in multiple layers to ensure adequate protection.

Once ingested, the enteric-coated drug or supplement passes through the stomach without being affected by the gastric acid. When it reaches the small intestine, which has a higher pH, the enteric coating dissolves, allowing the drug to be released and absorbed by the body.

It is important to note that enteric coating does not alter the drug itself; it only provides a protective barrier and controls its release and absorption in the gastrointestinal tract.

Applications of Enteric Coating

Enteric coating finds application in various pharmaceutical and nutraceutical products. Some common examples include:

  • Delayed-release tablets or capsules: These formulations are used to provide a gradual and targeted release of the active ingredient.
  • Probiotics and prebiotics: Enteric coating is used to protect the delicate bacteria or other microorganisms from the acidic environment of the stomach so that they can reach the intestines alive and exert their beneficial effects.
  • Enzymes: Enteric coating can be applied to enzymes that need to remain intact in the stomach and be released in the small intestine for optimal activity.
  • Fish oil supplements: Enteric coating is often used in fish oil capsules to prevent fishy aftertaste or burping by delaying the release of the oil until it reaches the small intestine.

Advantages of Enteric Coating

Enteric coating offers several advantages:

  • Improved bioavailability: Enteric coating helps protect the drug from degradation in the stomach, enhancing its absorption and bioavailability.
  • Reduced side effects: By preventing direct contact between the drug and the stomach lining, enteric coating reduces the risk of stomach irritation and associated side effects.
  • Enhanced patient compliance: Enteric coating can be used to improve the taste or odor of a drug, making it more palatable and easier for patients to take.

Conclusion

Enteric coating is a pharmaceutical technology that allows drugs or supplements to be protected from the acidic environment of the stomach and targeted to the small intestine. It provides advantages such as improved drug stability, controlled release, targeted delivery, and reduced side effects. Enteric coating finds application in various pharmaceutical formulations, including delayed-release tablets, probiotics, enzymes, and fish oil supplements. Understanding the concept of enteric coating can help individuals make informed decisions about their medication and supplement choices.

Definition of Enteric Coated

Enteric coating is a pharmaceutical technology that involves coating a drug with a special polymer or material that prevents it from dissolving in the stomach and instead releases it in the small intestine. This protective coating helps to protect the drug from the acidic environment in the stomach, ensuring that it reaches the intended site of action in the intestines.

Enteric coating is primarily used for medications that are sensitive to stomach acids or that can cause gastric irritation. It is commonly used for drugs such as NSAIDs (non-steroidal anti-inflammatory drugs) and certain oral antibiotics.

The enteric coating can delay the release of the drug, providing a timed-release effect, or it can be designed to release the drug under specific conditions, such as in a pH-dependent manner. This ensures optimal absorption and bioavailability of the medication.

Overall, enteric coating is an important technique in the field of pharmaceuticals, ensuring the efficacy and safety of medications by protecting them from the harsh gastric environment and delivering them to the desired location in the intestines.


Key Takeaways

  • Enteric coated means that a medication or supplement has a special coating designed to protect it from being broken down by stomach acid.
  • The coating allows the medication or supplement to pass through the stomach intact and be released in the intestine, where it is better absorbed.
  • This type of coating is commonly used for medications that can cause stomach irritation or need to be released slowly over time.
  • Enteric coated medications should not be crushed or chewed, as this can break the coating and affect the medication's effectiveness.

Frequently Asked Questions

In this section, we will answer some commonly asked questions regarding the meaning of enteric coated.

1. What does enteric coated mean?

An enteric coating is a protective layer applied to oral medications. It is designed to prevent the drug from being released in the stomach and instead releases it in the small intestine. This coating is made up of a material that is resistant to the acidic environment of the stomach.

The purpose of enteric coating is to protect the medication from the stomach acid, which can degrade certain drugs, rendering them ineffective. By releasing the medication in the small intestine, enteric coating ensures that it is absorbed properly into the bloodstream and delivered to the targeted site of action.

2. How does enteric coating work?

Enteric coating works by providing a protective barrier around the medication. This barrier prevents the medication from dissolving in the stomach and instead allows it to pass through to the small intestine before it begins to dissolve.

The enteric coating is designed to withstand the acidic environment of the stomach, but it can be broken down by the alkaline environment of the small intestine. Once the enteric coating reaches the small intestine, it starts to dissolve, allowing the medication to be released and absorbed into the bloodstream.
