Capsule manufactured by Roche. Drug capsules of this type were invented by the American drugs manufacturer Eli Lilly. The drug to be taken is contained within a soft gelatin casing which disolves in the stomach after the capsule is swallowed. The shape and texture of the capsule makes it easier for the patient to swallow than conventional tablets, and also means the patient will not experience any unpleasant taste that the powder inside may have.
