AR-CAPS® Acid Resistant Capsules

Produced from an exclusive formulation of hypromellose and proprietary polymers, AR-CAPS® gastric acid-resistant hard capsules prevent the release of drugs in the stomach, making them a cost-effective, quality choice for a vast range of enteric delivery pharmaceutical applications. AR-CAPS® deliver medicine by disintegrating in the duodenum for intestinal absorption, and are especially suitable for the delivery of probiotics and enzymatic formulations. With AR-CAPS®, costly and complex enteric coating processes are completely eliminated.


Safeguarding Your Formulation

AR-CAPS® are naturally acid resistant, which eliminates the need for added chemicals, solvents or other coatings to delay the release of your formulation as it passes through the digestive tract. The capsule retains its stability against the pH levels of the stomach, but breaks down when it reaches the higher pH levels of the small intestines. AR-CAPS® have a low moisture content, making them ideal for moisture sensitive or hygroscopic formulations. Suitable for Pharmaceutical applications only.
