Dilaudid etc. (hydromorphone) is a narcotic analgesic which acts on the central nervous system (CNS) to relieve moderate to severe pain.
Hydromorphone is 7-10 times more analgesic than morphine, with a shorter duration of action. It manifests less sedation, less vomiting, and less nausea than morphine, although it induces pronounced respiratory depression.
