DBcaps® Over-Encapsulation Capsules

For containment and blinding of comparator products in double-blinding studies, look to DBcaps® capsules.

Specially Designed For Clinical Trials

DBcaps® two-piece gelatin or HPMC capsules were developed with a tamper evident design to specifically address the clinical trial challenges of testing without bias.

The wider diameter of opaque DBcaps® capsules allows containment and blinding of large-diameter or uniquely-shaped tablets or other comparator products, while their shorter length makes them easier to swallow.

  • Seven of the eight different sizes of DBcaps® capsules are always in stock for double blinding a wide variety of comparator product shapes and sizes – no need to split, grind or alter your original dosage form
  • Active comparator products can be discreetly enclosed to improve patient compliance and tamper evident design prevent bias
  • Avoid concerns regarding alteration of the dosage form since there is no need to split or grind tablets
