What Biodone Forte is used for and how it works:
Biodone Forte has been approved for use in treating people with a dependency on opioid analgesic drugs.
The active ingredient in Biodone Forte is methadone hydrochloride. This belongs to the class of drugs known as opioid analgesics. Other well-known drugs that belong to this group include codeine, morphine and heroin.
Biodone Forte works like other opioid analgesic drugs and so it may be used to replace heroin or other morphine-like drugs. Because Biodone Forte tends to stay in the body longer, it helps stop the withdrawal symptoms that are experienced by people who are dependent on opioid drugs. The withdrawal symptoms are less intense but more prolonged than those produced by morphine or diamorphine. They develop more slowly and do not usually appear until 24 to 48 hours after the last dose.
