Propoxyphene (dextropropoxyphene Darvon) is structurally related to methadone but is much less potent as an analgesic. Compared with codeine, propoxyphene is approximately half as potent and is indicated for the treatment of mild pain. It is not antipyretic or antiinflammatory like aspirin and is less useful than aspirin in most cases of mild pain. Toxicity from propoxyphene, especially in combination with other sedatives, such as alcohol, has led to a decrease in its use. Death following ingestion of alcohol in combination with propoxyphene can occur rapidly (within 20 minutes to 1 hour). The drug is not indicated for those with histories of suicide or depressive illnesses. 

Heroin is a Schedule I drug morphine, codeine, fentanyl, hydrocodone, hydromorphone, and oxycodone are Schedule II drugs codeine plus aspirin or acetaminophen is Schedule III propoxyphene is Schedule IV and codeine sold over the counter is Schedule V. 

Propoxyphene is chemically related to methadone but has low analgesic activity. Various studies have reported its potency at levels ranging from no better than placebo to half as potent as codeine that is, 120 mg propoxyphene = 60 mg codeine. Its true potency probably lies somewhere between these extremes, and its analgesic effect is additive to that of an optimal dose of aspirin or acetaminophen. However, its low efficacy makes it unsuitable, even in combination with aspirin, for severe pain. The increasing incidence of deaths associated with its use and misuse has caused it to be scheduled as a controlled substance. Moreover, banning its use in the United States is under consideration. 

Propoxyphene (Schedule II) is another opiate prescribed for pain which is much weaker than those mentioned above. Notice the structural similarities to methadone. Its effects last longer than many other drugs in this class which means it can be taken less frequently and the potential of abuse will be lessened. It can also be formulated with aspirin or acetaminophen in order to have a summation effect. 

Accelerated or stress stability studies for the purpose of predicting sample shelf life at normal conditions have been investigated for many years. In addition, some examples of stress stability studies for sample comparison have been described. Goldberg and Nightingale (25) compared the stability of aspirin in a combined dosage form with propoxyphene. The hydrolysis...

Analgesics Analgesics or nonsteroidal anti-inflammatory drugs are often effective in mild-to-moderate migraine. Aspirin, acetaminophen, naproxen, propoxyphene, acetaminophen with butalbital, and caffeine are all effective in treating a migraine attack. 

Propoxyphene, along with aspirin, ace-tominophen, and ibuprofen are among the most widely used agents for the treatment of mild to moderate pain. 

One such drug is propoxyphene (Darvon), a prescription analgesic widely used in recent years. Sometimes it is combined with aspirin and caffeine to make it more effective. Despite enthusiastic claims of its manufacturer, most doctors and patients have found Darvon to be not much more effective than aspirin (Some even feel that when it is combined with aspirin, it is the aspirin that Joes most of the work.) Besides, the abuse potential of Darvon IS of the same sort as that of the strong narcotic analgesics, ft took some time for doctors to acknowledge the existence of Darvon abuse, but they are now very familiar with it and much more cautious about dispensing the drug.
