Pharmaceutical advancements have brought innovative ways to enhance drug delivery, and enteric coating is among the most significant. You’ve probably heard of it about certain tablets and capsules, but what exactly is it?
This article dives into the details of enteric coating, its uses, and why it’s a game-changer for specific medications and supplements.
An enteric coating is a layer applied to tablets or capsules that prevents the medication from dissolving in the stomach. Instead, it allows the drug to pass intact through the stomach’s acidic environment and dissolve in the alkaline conditions of the small intestine.
This type of coating is crucial for medications or supplements that:
Commonly used in pharmaceuticals and supplements, enteric coatings ensure drugs are released at the right time and place in the digestive system.
In the pharmaceutical industry, enteric-coated medication is a type of “delayed-release” formulation. It acts like a chemical timer. Unlike standard pills, it does not release the drug immediately.
Here are a few common examples of enteric-coated drugs:
Enteric-coated ibuprofen minimizes stomach irritation, a common side effect of NSAIDs (nonsteroidal anti-inflammatory drugs). By bypassing the stomach, it helps reduce gastrointestinal discomfort while maintaining its pain-relieving and anti-inflammatory effects.
Probiotics are live microorganisms that need to survive stomach acid to reach the gut. Enteric-coated probiotics protect these beneficial bacteria, ensuring they are delivered where they are most effective—your intestines.
Serrapeptase is an enzyme that reduces inflammation and promotes tissue repair. However, stomach acid can degrade it. With enteric-coated serrapeptase, the enzyme stays intact until it reaches the small intestine, where it can be absorbed effectively.
Fish oil supplements are abundant in omega-3 fatty acids. However, they are susceptible to degradation in stomach acid. Enteric-coated fish oil prevents premature breakdown, ensuring better absorption and eliminating the unpleasant fishy aftertaste.
Probiotics are live microorganisms. They must reach the gut alive to provide health benefits. This makes enteric coating for probiotics a gold standard in the supplement industry.
Identifying an enteric-coated tablet can be tricky if you don’t know what to look for. Here are some signs that a pill might have an enteric coating:
If in doubt, consult your pharmacist or healthcare provider for confirmation.
While enteric coatings offer significant benefits, they aren’t without drawbacks. Here are some potential disadvantages:
The primary difference between enteric coating and non-enteric coating lies in their functionality:
Choosing the right coating depends on the drug’s purpose and desired absorption site.
Breaking, crushing, or chewing an enteric-coated tablet can completely negate its purpose. These actions destroy the protective coating, exposing the medication to stomach acid. This not only reduces its effectiveness but can also lead to side effects such as stomach irritation. Always swallow enteric-coated pills whole to ensure proper drug delivery.
For example, many wonder, “Can enteric-coated tablets be crushed?” The answer is: NO. Crushing defeats the coating’s protective function.

1. What is enteric-coated?
It is a tablet or capsule with a layer that resists stomach acid and dissolves only in the small intestine.
2. Why are probiotics enteric-coated?
To protect live bacteria from being destroyed by stomach acid so they can reach the gut effectively.
3. How do enteric coatings work?
They use pH-sensitive polymers. These materials stay solid in acid ($pH < 5$) but dissolve when they reach the alkaline environment of the intestine ($pH > 5.5$).
Quick Answer Continuous manufacturing pharmaceutical systems merge blending, granulation, and compression into one unbroken line to meet GMP compliance under 21 CFR Part 11. These lines run in-line, real-time quality monitoring instead of end-of-batch testing, typically handling 5 to 40 kg per hour. Canaan’s integrated pharmaceutical continuous manufacturing lines are built to meet these standards, […]
Quick Answer Cleaning validation in pharmaceutical manufacturing is the documented proof that equipment meets a set residue limit every time. A validated wash runs pre-rinse, detergent wash, rinse, and dry stages under fixed time, temperature, and pressure parameters. Canaan’s QD Series washing stations combine automated washing and drying in one controlled cycle, with key process […]
Quick Answer A CIP system cleans fixed pharmaceutical equipment, such as coating machines and fluid-bed dryers, by circulating water and cleaning solution through the system without disassembly. Programmed pressure, temperature, and cycle times help keep each cleaning run consistent. Canaan uses built-in CIP for fixed equipment and QD Series washing stations for bins and IBCs. […]
