The system is a four-layer laminate of, from the top: a protective backing; a gelled, mineral oil-polyisobutene-clonidine reservoir lamina that is the source of the clonidine for the continuous constant dosage; a microporous membrane that controls the constant dosage rate; and a gelled, mineral oil-polyisobutene-clonidine contact adhesive layer that is the source of the clonidine for the priming dose and the means by which the system is attached to the skin.
