What is Darvon?
Dextropropoxyphene is sometimes combined with acetaminophen or aspirin. Trade names include Darvocet-N and Di-Gesic, Darvon with APAP (for dextropropoxyphene and paracetamol) and Darvon with ASA (for dextropropoxyphene and aspirin). The British approved name (i.e. the generic name of the active ingredient) of the paracetamol/dextropropoxyphene preparation is "co-proxamol" (sold under a variety of brand names); however, it has been withdrawn since 2007, and is no longer available to new patients, with exceptions. The paracetamol combination(s) are known as Capadex or Di-Gesic in Australia, Lentogesic in South Africa, and Di-Antalvic in France (unlike co-proxamol, which is an approved name, these are all brand names).
Dextropropoxyphene is known under several synonyms, including:
- Alpha-d-4-dimethylamino-3-methyl-1,2-diphenyl-2-butanol propionate
- [(2S,3S)-4-(Dimethylamino)-3- methyl-1,2-diphenylbutan-2-yl] propanoate
- (+)-1,2-Diphenyl-2-propionoxy- 3-methyl-4-di-methylaminobutane
