Acetaminophen-propoxyphene Napsylate

Dextropropoxyphene, manufactured by Eli Lilly and Company, is an analgesic in the opioid category. It is used to treat mild pain and is additionally an anti-tussive and local anesthetic.

Dextropropoxyphene is sometimes combined with acetaminophen or acetylsalicylic acid. Trade-names include Darvocet-N and Di-Gesic2 Darvon with APAP for dextropropoxyphene and paracetamol and Darvon with ASA for dextropropoxyphene and aspirin.3 The paracetamol combination(s) are known as Capadex or Di-Gesic in Australia, Lentogesic in South Africa, and Di-Antalvic in France. The paracetamol preparation is known as co-proxamol in the UK, but has been withdrawn since 2007 and is no longer available to new patients.
