What’s the Difference Between Enteric-Coated and Plain Aspirin?

Aspirin is a widely available medicine that has been used in pain relief since the time of the Sumerians, some 4000 years ago.  Often taken to relieve pain or reduce fever, aspirin also plays a role in reducing the risk of heart disease.  For those taking oral low dose aspirin long term under medical supervision, the type of formulation can matter—especially for the stomach. In this article, we explore what enteric-coated aspirin is, how it works, and why it might be recommended for some people.

What is Enteric-Coated Aspirin?

Enteric-coated aspirin is a type of aspirin that has a special coating designed to resist the acidic environment of the stomach. Instead of dissolving immediately after swallowing, it passes through the stomach intact and begins to dissolve in the small intestine, where the conditions are more neutral to alkaline.  This tablet design helps to reduce the risk of stomach irritation and potential gastrointestinal discomfort.

When Might Enteric-Coated Aspirin Be Recommended?

Your doctor may recommend an enteric-coated version of aspirin if you’re taking it daily for protection against heart disease.  According to clinical guidelines, using enteric-coated aspirin to prevent heart disease can be beneficial, especially in people who are at risk of upper gastrointestinal bleeding.

However, enteric-coated aspirin is not suitable for everyone, and should not be used in emergency situations due to the delayed absorption.  This is why it’s essential to only use it under medical supervision.

Talking to Your Healthcare Professional

Before starting or switching aspirin formulations, it’s important to have a conversation with your doctor or pharmacist to ask things like:

  • Is enteric-coated aspirin suitable for my personal condition/situation?
  • Are there any side effects I should be aware of?
  • How long should I take aspirin for?

Your healthcare provider will consider your medical history, other medications, and individual risk factors to recommend the best option for you. Never start or stop aspirin therapy without their guidance.

Why Choose Cartia?

Cartia is a low-dose aspirin product that has a special enteric coating known as ‘Duentric’ technology.  This coating helps ensure the aspirin passes through the stomach and dissolves in the upper intestine, reducing the likelihood of stomach irritation when taken long-term.

It’s important to remember that Cartia is designed for long-term use under medical supervision, and should only be used as directed by your doctor, as it may not be suitable for everyone.
