Abstract

A colonic drag delivery composition is provided and comprises a starch capsule containing a drug, the starch capsule being provided with a coating such that the drug will only be released from the capsule in the colon. The coating may be a pH-sensitive material, a redox-sensitive material or a material broken dawn by specific enzymes or bacteria present in the colon. The drug to be delivered may be one for local action in the colon, or a systemically active drug to be absorbed from the colon.
