Dihydrocodeine is a narcotic analgesic which possesses pharmacological properties similar to those of morphine. 30mg given parenterally has been shown to have an analgesic potency equivalent to that of 10mg morphine. In a study of oral analgesics for the relief of chronic pain, the same dose was found to be equivalent to 100mg of pethidine. The duration of action of dihydrocodeine is about 4-5 hours, similar to morphine and codeine.
Dihydrocodeine Elixir has been shown to have a satisfactory pharmacokinetic profile by many years of successful clinical experience.
There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
