HPMC delayed release vegetable capsule
HPMC delayed release vegetable capsules are also divided into antacid capsules and enteric capsules.
Anti-acid Capsules
Anti-acid capsules inherit the advantages of vegetable capsules, while delaying disintegration. Limited release in gastric juice, standard release amount: no more than 15% dissolved in 2 hours at pH 1.2.
Material: HPMC and special gel with acid resistance
Characteristics: Good anti-acid ability.
Application: drugs with strong stomach irritation or bad odour, biochemical preparations, health products, etc.
Advantages: pure plant origin, low moisture, no-brittle, high stability; good acid resistance and enzyme resistance without secondary coating, which can protect acid-sensitive ingredients from being affected.
Enteric-coated capsules
The capsule shell is incorporated with special medicinal polymer materials or specially treated so that it does not dissolve in the gastric juice, but only disintegrates and dissolves in the intestinal juice to release the activity, which is localised in the small intestine, large intestine and released by the drug delivery techniques.
Function: It does not dissolve in the stomach, but can be positioned for dissolution in each segment of the intestinal tract for precise release.
Advantages:avoids irritation of the stomach by the drug, allowing the contents to be released safely and effectively in the intestine for better absorption.
Application:Suitable for drugs that are sensitive to water or hygroscopic and are highly irritating to the stomach or require release in the intestine, providing a new way of intestinal positioning for drug delivery.
