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. Currently, dihydrocodeine and nicocodeine are used as second-line codeine replacements. The other dihydromorphinone used as an antitussive is hydromorphone (Dilaudid cough syrup); the other narcotic antitussives are either more directly related to codeine or not related at all (open chain methadone relatives and thiambutenes).
