Encap Drug Delivery, based in the UK, has been awarded European and US patents for the company's DuoCap capsule delivery system. DuoCap is just what it sounds like, a capsule-within-a-capsule, or a kind of Matryoshka doll of the drug-delivery world. The inner and outer capsules may contain the same active drug, but with an immediate-release formulation on the outside and timed release on the inside. Or each layer could contain different different active ingredients for combination therapies. Encap release
