 Thebacon was invented in Germany in 1924, four years after the first synthesis of hydrocodone.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).Thebacon is indicated for moderate to moderately severe pain and dry painful coughing, like hydrocodone.
