Thebacon is an opioid agonist narcotic analgesic of the middle range and a strong antitussive, primarily used in Europe, although it is no longer in common use.

  • A semisynthetic opioid
  • Similar to hydrocodone
  • Indicated for moderate to moderately severe pain and dry painful coughing, like hydrocodone
  • Duration of action in the range of 5 to 9 hours
  • Doses typically start at 5 mg
  • The drug is most commonly taken orally as an elixir, tablet, or capsule
  • Most commonly synthesised from thebaine
  • Thebacon is marketed as its hydrochloride salt under the trade name Acedicon, and as its bitartrate under Diacodin and other trade names
  • Invented in Germany in 1924, four years after the first synthesis of hydrocodone

Thebacon's analgesic and antitussive potency is slightly higher than that of its parent compound hydrocodone, which gives it approximately eight times the milligramme strength of codeine
