Not all vegetarian capsules behave in the same way after swallowing. Standard HPMC capsules are designed to open normally, while delayed-release capsules are designed to resist opening for longer under acidic conditions.
Standard HPMC vs delayed release
Standard HPMC capsules are a popular plant-based alternative to gelatin and are suitable for many powders. Delayed-release HPMC capsules are different: they are intended for applications where delaying capsule opening may be useful.
Why might someone choose delayed release?
Common reasons include protecting acid-sensitive ingredients, changing where a powder is released, or avoiding immediate release in the stomach. Examples often discussed include probiotics, digestive enzymes and other acid-sensitive ingredients.
Are delayed-release capsules the same as enteric-coated capsules?
No. “Delayed release” and “enteric coated” should not automatically be treated as identical terms. DRcaps® are delayed-release HPMC capsules and do not require a separate enteric coating.
How long do DRcaps® delay release?
DRcaps® are designed to provide delayed opening compared with conventional capsules. Actual behaviour depends on the conditions of use, so they should not be described as guaranteeing delivery to one exact location in every person.
Which should I choose?
For ordinary powders where delayed release is unnecessary, standard HPMC may be sufficient. For probiotics, enzymes or other ingredients where gastric conditions are a concern, delayed-release capsules may be worth considering.
Important: Empty capsules are a delivery format, not a treatment. If you are encapsulating a medicine or have a medical condition, ask a pharmacist or healthcare professional whether changing the original dosage form is appropriate.
