Abstract
A linker for multicomponent dosage form has a preformed drug substance tablet and an injection molded jacket including one or both axial jacket ends open for dispensing the preformed drug substances. The jacket has snap-fit connection elements on the outer surface adjacent each end for engagement with complementary snap-fit element on capsule-type and cap-type dosage form units. Another multicomponent drug form linker is injection molded with a raised circumferential band and snap-fit elements between the band and respective ends engageable with complementary snap-fit elements on dosage form units to provide compressive abutting contact between ends of the units and the band. The band can have an axially tapered outer surface to accommodate dosage form units of different diameters. Still another multicomponent dosage form linker has separable male and female parts each engageable with, and separately sealing, respective dosage form units to be linked. Circumferential complementary grooves, groove segments, ridges and ridge segment-type snap-fit elements are disclosed, as are dosage forms using the above-described linkers.
