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.

With AR-CAPS®, costly and complex enteric coating processes are completely eliminated.
