Duragesic® is an example of which transdermal patch type?

Explanation:
Duragesic operates as a reservoir-type transdermal system. The fentanyl is contained in a separate drug-filled reservoir and release is controlled by a rate-controlling membrane before the drug passes through the adhesive to the skin. This setup provides a steady, predictable delivery over time. In a matrix-type patch, the drug is dispersed within the adhesive or a single polymer matrix, and release happens by diffusion through that matrix rather than through a separate reservoir and controlling membrane. So the defining feature of Duragesic is the separate reservoir with a controlling membrane, making it a reservoir-type patch.
