Davocet (Dextropropoxyphene) is an analgesic in the opioid category. It is used to treat mild to moderate pain and as an anti-tussive. It can be used to ease surgical pain both prophylactically and palliatively. It is possible to classify it as a mild opioid pain-killer, however it is considered no more effective than aspirin in treating pain. Davocet (Dextropropoxyphene) is sometimes combined with paracetamol (acetaminophen) or aspirin. Trade-names include Darvocet-N for dextropropoxyphene and paracetamol and Darvon-N with ASA for dextropropoxyphene and aspirin.[3][4] It is also sometimes sold in combination with caffeine in order to deter abuse and augment analgesia. There is no peer-reviewed evidence that this combination is any more effective than paracetamol alone. There is significant anecdotal evidence from patients that Darvocet is more effective than paracetamol, but a third of patients suffering chronic pain report relief from that pain when treated with placebo. It is manufactured and marketed by Eli Lilly and Company. It is an optical isomer of levopropoxyphene. The racemic mixture is called propoxyphene. Some preparations that contain dextropropoxyphene include Distalgesic and Doloxene.
