ABSTRACT:
A sleeve shaped structure covers a portion of the transport area of a diffusional or osmotic delivery device. The structure is durable and inert to the use environment. Markings on the structure indicate where breaking or cutting will produce a predictable alteration in delivery rate. Among other attachment means, a water soluble adhesive maintains the structure on the delivery device.
